DISEASES OF THE LARYNX.
BY LOUIS ELSBERG, A.M., M.D.
Inflammation, Erosion, and Ulceration of the Epiglottis.
Of the diseases of particular portions of the larynx, those of the epiglottis deserve especial attention in a work designed for general practitioners, on account of the comparative ease of recognizing and treating them if understood, and the promptness their management requires. They occur more frequently than is generally supposed, their symptoms are often erroneously ascribed to other affections, and they may lead to extensive disease in the respiratory apparatus, sometimes of a very serious character. Adjacent portions of the root of the tongue and pharynx or of the larynx are apt to be coaffected. In diseases which commence in the pharynx, usually the lingual surface, and in such as spread upward from the larynx only the laryngeal surface, of the epiglottis is involved mainly or exclusively.
Before describing the affections of the epiglottis a few words must be said of the manner of using the tongue-spatula. Physicians almost without an exception press the tongue from above downward and from before backward; but in order to bring the epiglottis into view in the majority of instances the proper method is just the opposite of this—viz. from below upward and from behind forward. Place the spatula far back, lift up the base of the tongue, and draw it forward. The usual manner of depressing the tongue—no matter how good or bad an instrument may be used, and an ordinary spoon-handle serves the purpose better than most of the so-called tongue-depressors—pulls upon and irritates the pharyngo-glossal fold, and often hides the epiglottis instead of bringing it into view, besides producing intolerance and intractability. The blade of the tongue-spatula should be long (at least four, still better five, inches), slightly curved downward, not more than from half an inch to one inch wide, and joined to the handle at an obtuse angle.
1. Acute inflammation of the epiglottis is usually caused by taking cold, exposure to draughts, wet, sudden changes of temperature, etc. The symptoms are local pain and difficulty of swallowing; in severe cases also some dyspnoea and dysphonia. Only occasionally there is a hemming cough, and that a peculiar one, induced (usually voluntarily) by a feeling of a foreign body at the root of the tongue. The diagnosis is made by means of the tongue-spatula and laryngeal mirror, the epiglottis being seen to be inflamed and swollen. When the lower portion, the so-called cushion of the epiglottis, is affected, the mirror is required for diagnosis. In this case suppuration is apt to occur. The prognosis is good with attention; neglected epiglottitis may cause great discomfort, and even death. Treatment must be antiphlogistic and supporting. For mild cases systemic and dietetic regulation suffices, with externally either hot fomentations or cold applications as the patient can best bear. Severer cases require in addition leeches and ice to the part; and cases of threatened suppuration, medicated and unmedicated steam inhalation, and, when necessary, lancing of the abscess through the mouth under guidance of the mirror. After the acute inflammation has subsided, local treatment may become necessary to hasten or produce complete restoration, as will be noticed in Chronic Epiglottitis.
Inflammatory oedema of the epiglottis will be considered under the head of Laryngeal Oedema.
Chronic inflammation of the epiglottis is usually the result of uncured acute epiglottitis or of laryngitis. The main symptom is dysphagia. The epiglottis is found swollen and more or less discolored. Not only tongue-spatula and laryngeal mirror, but also the finger carefully introduced into the mouth, may ensure the diagnosis, especially if the upper portion be affected: then the thickened epiglottis is seen and felt as a peculiar rounded tumor at the base of the tongue. Oedema is distinguishable from chronic inflammation by both sight and touch. As to prognosis, it must be observed that the process of restoration is slow and that there is always danger of acute exacerbation. The treatment consists in attention to the general health and habits and in local applications. The latter are indispensable, and should be made by means of an instrument (Elsberg's applicator or the like) carrying a little wad of cotton or sponge. Some prefer a brush: to such individual preference no objection need be made, but powders and sprays are not advisable. The remedies to be applied should be in liquid form, and belong pharmacologically to the class of alteratives. Iodine, iodoform, and silver nitrate in solution are most useful. In subacute inflammation (see above) potassium bromide and chlorate, respectively, in saturated aqueous solution, may be applied once a day, or a saturated solution of iodoform in sulphuric ether, or ten grains of crystallized silver nitrate dissolved in an ounce of water, every other day. In chronic epiglottitis the tincture or compound solution of iodine, the ethereal solution of iodoform, and the watery solution of silver nitrate, in degrees of concentration varying according to the severity of the case and the individuality of the patient (the choice of either of the three agents, the repetition of the same, or the change from one to the other depending upon the effect produced), should be accurately applied to the part affected by means of the laryngeal mirror or the tongue-spatula.
2. The most frequent, and at the same time the most neglected, morbid condition of the larynx is erosion of the free edge of the epiglottis. Louis has called attention to the epiglottic erosions in connection with tubercular phthisis: he found them present in about one-sixth of the patients who died of that disease, and they are caused, in his opinion, by the constant passage of pus over the part. Horace Green was the first who pointed out that they are also frequently met with independently of tubercular disease. According to him, "These instances, for the most part, have been found occurring in those cases in which a persistent, teasing cough, following chronic follicular disease or common catarrhal inflammation, has obstinately resisted all the ordinary measures for its arrestment. On depressing the tongue in such cases by means of the ordinary bent spatula or tongue-depressor, so as to bring the epiglottis into view, this cartilage has been found frequently inflamed, vascular, and its superior border marked at one or more points by distinct erosions. In much the largest proportion of cases these erosions make their first appearance on the left superior edge of the epiglottis. Next in frequency they will be found occupying its centre, and occasionally, but very rarely in comparison with the two preceding locations, they have been observed upon its right border. These erosions are not readily detected, at first, by the inattentive observer, as they are quite small, are only slightly depressed, with a pallid base, sometimes a little reddened, and with whitish, linear edges. The surrounding mucous membrane is generally inflamed, its delicate network of superficial vessels is red and injected, and the epiglottis itself more or less thickened." Sometimes epiglottic erosions exist without much cough, and certainly a cough can exist without erosions; but the two seem frequently to act interchangeably as cause and effect; and certain it is that a cough, from whatever cause, once firmly established, when such erosions have supervened rarely if ever yields so long as the erosions continue, and often stops when they are cured. According to my experience, the left and right sides of the upper border are affected with about the same frequency, and oftener than the centre. The erosions are catarrhal in their nature, even in tubercular subjects; in non-specific cases they degenerate exceedingly rarely into ulcers—i.e. they may exist for years without involving any tissue below the epithelium unless the patient is or becomes syphilitic or phthisical. They often produce symptomatically, especially in the beginning, more hemming than cough. The diagnosis is easy on thorough inspection of the epiglottis. Prognosis is generally favorable, except in phthisical cases; in others, although they sometimes prove exceedingly obstinate, they usually yield with surprising promptness to topical treatment. In specific cases, and even in chronic naso-laryngeal catarrh, they are apt to recur, however. A cotton wad dipped in a strong solution (gr. xxx–drachm j ad ounce j water) of either silver nitrate or gold chloride must be brought accurately into contact with the eroded spots once in twenty-four or forty-eight hours; ordinarily only a fortnight's treatment is necessary, except for the frequently accompanying (or underlying) catarrhal condition of a more or less large extent of the upper respiratory mucous membrane. In very severe cases a few applications at longer intervals of a still stronger solution (drachm j–drachm ij), or even of the solid silver or gold preparation, may be required.
3. Epiglottic ulcerations differ from erosions in the fact that the latter are confined to the epithelium, while the former involve also deeper structures. It has been asserted by some observers that an erosion is always the first stage of an ulceration, and by others that the one never passes into the other. I believe that both of these extreme assertions are incorrect; but if it were possible to distinguish, clinically or pathologically, every case of superficial ulceration from erosion, I might incline to agree with the latter. Histologically, epiglottic ulceration affects the mucous membrane, glands, or cartilage. Most frequently it seems to originate in the follicles. As Horace Green has long ago pointed out, "At first an enlarged or pimple-like follicle appears on the border of the epiglottis, surrounded by an inflamed and highly-injected portion of mucous membrane. Soon the follicle softens, and degenerates into an ulcer with irregular edges and an inflamed and reddened circumference. In many instances these ulcers remain for some time superficial, destroying only the mucous membrane; in others they penetrate deep into the fibro-cartilage, and occasionally they result in the total destruction of the epiglottis." Sometimes the ulcer seems to originate in the superficial layer of the mucous membrane, the molecular death proceeding from the surface downward; these are the cases which in the beginning cannot be distinguished from erosions. Both these kinds of ulceration of the epiglottis occur without, and with, grave constitutional affections, but the cartilaginous tissue usually, though not invariably, remains intact except in phthisis, syphilis, and cancer. Lupus, lepra, and glanders also give rise to ulceration, and sometimes to much accompanying thickening of the epiglottis. The seat of the ulcers is, as a rule, on the upper border and laryngeal surface of the epiglottis, only exceptionally on the lingual. Together with ulcers on the laryngeal face those on the lingual face are found, but not vice versâ. Ulcers of the epiglottis are usually small, but numerous, worm-eaten in appearance, and frequently pass to other laryngeal structures. Though occasionally resulting from tuberculosis, syphilis, and other constitutional affections, they also occur as primary disease due to catarrh and local injury, but may become the antecedents, and in many instances the exciting cause, of other grave maladies. Indeed, I quite agree with Horace Green that they are often "not only among the earliest manifestations of thoracic diseases, but are themselves in many instances the true exciting cause of these affections; and furthermore, this postulate once established, that we have it in our power, by timely topical medication, to arrest, positively, cases of disease which otherwise would, and in many instances which do, terminate fatally."
The symptoms vary with the seat and extent of ulceration. Cough and the sense of irritation in the throat are usually present. "In several instances all the prominent rational signs, with some of the earlier physical manifestations, of pulmonary disease have been observed to follow long-continued ulceration of the epiglottis; all of which symptoms have been seen to disappear after these lesions have been healed." When the upper border is extensively affected, and still more when either surface, especially the lower portion of the laryngeal surface, be involved, there is difficulty of swallowing; the pain is due often as much to surrounding inflammation as to the epiglottic lesion. In some cases the voice also is affected.
The diagnosis of the existence of an ulcer is easily made when the epiglottis can be seen not only with the spatula, but also with the laryngeal mirror. Its origin and nature are, however, not always easily recognized, and the patient's general condition and history, as well as the appearance of the ulcer, must be taken into account. The diagnosis of catarrhal epiglottic ulceration must be made only after other underlying conditions, as phthisis, syphilis, malignant disease, lupus, lepra, and glanders (see the articles on those subjects), have been excluded. The prognosis is good, except in cases of phthisis, syphilis, etc., or in which already a great deal of the cartilage has been destroyed; and even in these cases appropriate treatment will often give the patient much comfort. Appropriate constitutional treatment must be instituted in all cases in which the constitution is affected.
Topical treatment consists in the application of alteratives, astringents, stimulants, or sedatives, as the case may call for. Some cases may require once or more times touching with solid silver nitrate; watery solution of this remedy, varying in strength from gr. x to drachm ij to the ounce; solution of gold chloride of similar strength; of iron pernitrate and perchloride drachm ss–drachm j to the ounce; of zinc chloride (gr. x–drachm ss to the ounce); a solution of iodine in olive oil (gr. x–xxv ad ounce j with a few grains of potassium iodide), or of iodoform in sulphuric ether (drachm i–drachm ij ad ounce j); carbolic acid in glycerin (gr. v ad ounce j) or Magendie's solution of morphine, or a mixture of morphine and syrup of tolu (gr. 1/8–½ to a few drops),—have most frequently been beneficial in my hands. In many cases in which the pain on swallowing has been so great as to make deglutition almost impossible, I have succeeded in temporarily anæsthetizing the parts before a meal by applying, after cleansing them, a watery solution of cocaine hydrochloride (gr. xx ad ounce j). If, in spite of all, the difficulty of swallowing threatens the patient with starvation, feeding with the oesophageal tube must be resorted to.
Laryngeal Oedema.
DEFINITION.—Infiltration of a fluid or semi-fluid into the submucous connective tissue of the larynx.
SYNONYMS.—Oedema of the glottis (often incorrectly so called, as will presently be seen), Oedematous laryngitis, Phlegmonous laryngitis, Submucous laryngitis, Dropsy of the larynx, Angina laryngis infiltrata, Angina laryngea oedematosa, Angine infiltro-laryngée, etc.
CLASSIFICATION.—Cases of laryngeal oedema are classified as to their occurrence into acute and chronic, corresponding generally to inflammatory and non-inflammatory; as to the nature of the infiltration, into serous, purulent, sanguineous, sero-purulent, sero-sanguineous, etc.; as to the extent of the infiltration, into diffuse and circumscribed (the latter often leading to abscess-formation, and then called laryngeal abscess rather than laryngeal oedema, differing, however, from perichondric abscess); and as to the seat, into epiglottic, supraglottic, infraglottic, and glottic. When epiglottic, it implicates, besides the upper border, often the glossal, hardly ever the laryngeal, surface; in supraglottic, the ary-epiglottic folds, arytenoid region, ventricular folds, or ventricles are involved; in glottic, the interfibrillar connective tissue of the thyro-arytenoid muscle is infiltrated, very exceptionally, if ever, the submucous tissue of the vocal bands themselves;1 and in infraglottic, the submucous connective tissue down to the first ring of the trachea. Glottic oedema occurs extremely seldom, but the designation oedema glottidis is often used, no matter what portion of the larynx is affected. Laryngeal oedema usually affects both sides; occasionally one side more than the other, still more rarely one side exclusively.
1 Such a case has been positively reported, or I would deny the possibility of its occurrence.
ETIOLOGY.—Laryngeal oedema is seldom, if ever, idiopathic. Usually it accompanies or follows either some disease or injury of the larynx2 or neighboring structures or a constitutional affection. Acute oedema may be caused by catarrhal or diphtherial pharyngo-laryngitis; irritation from scalds, burns, caustics, foreign bodies (especially sharp ones), or other trauma; laryngeal ulcers, especially syphilitic and tuberculous; laryngeal perichondritis, tonsillitis, parotitis, or inflammation of cervical tissues on the one hand, and pyæmia and septicæmia, endocarditis, erysipelas, small-pox, scarlatina, measles, typhoid fever, typhus, or acute Bright's disease of the kidneys on the other. "It has ensued upon deglutition of very cold water and upon prolonged vocal efforts" (Cohen). Perichondritis and chondritis, tuberculous, syphilitic, carcinomatous, or typhoid ulcerations of the larynx, especially when deep-seated or extensive, are sometimes attended with acute, but more often with chronic, oedema. Non-inflammatory or chronic laryngeal oedema is sometimes part and parcel of general dropsy in consequence of heart, kidney, or lung disease: Horace Green has reported a case occurring in a man who had hydræmia from great losses of blood from hemorrhoidal tumors; and it is sometimes due to some impediment to free venous circulation in the laryngeal tissues, from paralysis of the walls of the vessels, mechanical obstruction, tumors of the thyroid body or in the mediastinum, etc. compressing the jugular veins, compression of the superior vena cava, etc.
2 According to Sestier, who has written (in 1852) the most elaborate treatise extant on the subject, four-fifths of all cases occur in other laryngeal affections.
Cohen mentions cases to show that acute iodism and mercurialization may cause laryngeal oedema. He also says that although occurring in individuals in good general health, it is more apt to take place in those of impaired constitution or recently convalescent from acute diseases; and in some instances there would appear to be some peculiar predisposition toward its occurrence the nature of which is not understood, for examples are on record of more than one attack in the same individual. Under all these circumstances the immediate exciting cause, when apparent, seems to be exposure to cold and moisture.
Laryngeal oedema is not a disease of childhood; exceptional under five years, it is very rare until after ten. Most cases occur between eighteen and thirty-five. After the sixtieth year it is again rare; and it occurs more rarely in women than in men.
SYMPTOMATOLOGY.—The symptoms of laryngeal oedema vary with the seat and degree—that is, according to the class to which the case belongs. Increasing interference with breathing is the most prominent symptom. Interference with swallowing, though not always present, is the next prominent. Sometimes the occurrence is so sudden, insidious, or overwhelming that the patient dies before aid can be procured. Such was Boerhaave's case of a man who during dinner suddenly spoke with a changed voice, which his companions took as a joke, and in a few minutes fell dead; Rühle's case of a servant-girl, who, a trifle hoarse, went out lightly clad on a cold morning and suffocated while going up stairs on her return; and the case of a patient of mine with subacute catarrhal laryngitis, who rode out behind a fast horse on a cold afternoon, and died, within ten minutes after entering his own house, from serous infiltration of the upper aperture of the larynx. A number of similar cases have been reported, but usually the disease runs its course less rapidly. When the ary-epiglottic folds are the seat of the oedema, the patient experiences either suddenly or gradually a difficulty of inspiration, while the expiration may be at first unimpaired, and with increasing sensation of constriction of the throat or of the presence of a foreign body, hoarseness, and stridor, but often without dysphagia, the most threatening paroxysms of suffocation supervene. When the epiglottis is the main seat, while respiration is also more or less impeded, swallowing is rendered painful, difficult, and sometimes impossible without choking and regurgitation through the nares, and the voice roughened and sometimes extinguished. When the arytenoid region is also affected, respiration and deglutition are still worse, aphonia is complete, the sense of irritation at the upper aperture of the larynx often amounting to pain, and the patient with great effort expectorates slightly. In oedema of the ventricular folds there is early aphonia and gradually increasing dyspnoea, which affects both expiration and inspiration, sometimes the former even worse than the latter. This makes the sufferer's efforts to breathe most frightful to witness, the feeble inspiration being accompanied by a slow whistling sound, and the expiration, despite most violent exertion, almost entirely shut off. Glottic oedema is, as before said, exceptional; when it occurs to any great extent apnoea ends the case unless operative relief is immediately afforded. In infraglottic oedema, which is exceedingly rare and chronic in nature, there is steadily increasing dyspnoea, wheezing, cough, and abundant expectoration.
In acute cases of supraglottic and epiglottic oedema the suffocative paroxysms may last several minutes, and recur at irregular intervals of a few hours with increased intensity. If not relieved, patients become wildly excited or terror-stricken; they may throw the chest forward, open the mouth, grasp the throat outside or thrust their hands into it, and make convulsive movements in their struggles for breath; with protruding eyes and flushed face they become cyanotic, the extremities cold, the pulse small and frequent; coma supervenes, and death. In chronic cases the symptoms are not so violent, though they may steadily progress to impending strangulation, but for a long time the dysphagia gives the patient much more distress than the dyspnoea.
In circumscribed acute cases leading to the formation of an abscess there is usually pain in a particular spot, and often general feverishness, in addition to all the symptoms before mentioned, according to the seat of the oedema. Sometimes the suffering in laryngeal abscess at its height is very intense. Perforation into the pharynx, oesophagus, or even externally, may take place, but usually the pus points into the larynx. When the pus is evacuated either spontaneously or by incision, violent choking, coughing, and hawking may occur, but after it is evacuated all dangerous symptoms usually rapidly subside.
In sanguineous infiltration the symptoms do not differ from serous or purulent oedema under the same circumstances. Hemorrhagic infusion is usually sudden, and the resulting stenosis often fatal. Muscular spasm or paralysis sometimes coexists with laryngeal oedema, and greatly adds to the interference with respiration.
PATHOLOGY AND MORBID ANATOMY.—The seat of the morbid process being the connective tissue, those localities of the larynx in which this tissue is most abundantly interposed between the mucous membrane and the cartilage are most liable to infiltration. I must say from my own experience that the epiglottis—particularly the glosso-epiglottic region—is most frequently affected,3 next the ary-epiglottic folds, then the arytenoid region, and then the ventricular folds. The ventricles and the vocal bands are very rarely involved. Infraglottic oedema is still more rare, and is never an extension of the supraglottic. The disease is never a primary one, and, though seated in the submucous connective tissue, it may have started with inflammation of either the overlying mucous membrane or the underlying perichondrium. Effusion of blood is generally limited to traumatic cases, but has ensued from mercurialization, small-pox, and typhus; purulent infiltration and abscess formation is the result of phlegmonous inflammation and breaking down of the tissue, occurring especially in the cushion of the epiglottis and in the ventricular and ary-epiglottic folds; but as a rule the effusion in laryngeal oedema is of a serous or sero-purulent character.4 In infraglottic oedema it is said to be fibrinous.
3 According to Sestier, the ary-epiglottic folds are affected in nearly every case, either alone or together with other parts.
4 In 90 cases Sestier found the infiltration serous 60 times, sero-gelatinous 6, sero-purulent 9, sero-purulent with plastic lymph 4, purulent 8 times, sero-sanguineous twice, and sanguineous once.
The mucous membrane covering the oedematous structures is tense and discolored; except in very inflammatory conditions it is yellowish, shimmering, and pallid. On cutting into the diseased parts often but little exudation takes place, and sometimes even squeezing between the fingers does not suffice to cause disgorgement.5 After the fluid is evacuated the parts collapse and the mucous membrane is left wrinkled and folded.
5 In 23 autopsies Sestier found that incisions into the oedematous structures made the liquid run out either without any or with slight pressure 10 times; with repeated pressure, with difficulty and only in small quantity, 6 times; and not at all, in spite of repeated incisions and pressure, 7 times.
DIAGNOSIS.—With the laryngoscope, the spatula, and the finger the seat, the degree, and often the nature of the infiltration can be determined. A successful laryngoscopical examination may sometimes require in such cases more than ordinary skill, and there is often so much tumefaction that the parts are not easily recognizable. The epiglottis may appear as a thick roundish tumor, or be of a more or less indistinct horse-shoe shape, overhanging the laryngeal aperture; the ary-epiglottic folds may be converted into large lateral cushions pressing against the arytenoid bodies, or be merged with the latter into huge, irregularly pear-shaped, oval, or globular masses; and the ventricular folds may be immensely tumefied, or else, by means of the swelling and the being pushed into a horizontal position of the whole lateral lining of the upper laryngeal cavity, may be obliterated altogether. Glottic oedema never occurs except with supraglottic, and the upper surface of the vocal bands may look elevated, arched, and bladder-like, even if only the thyro-arytenoid muscles are infiltrated. In infraglottic oedema there is usually neither epiglottic nor supraglottic oedema; pads are seen underneath the vocal bands, either ring-shaped or projecting from side to side toward the middle line, and fill up to a greater or less degree the rima glottidis. The oedematous parts have sometimes a pinkish, but usually a yellowish, translucent or semi-translucent aspect. Accumulation of pus lessens the translucency and sometimes makes the yellow more marked. Sanguineous infiltration shows a bluish-red or livid discoloration. In chronic oedema the color is lighter, sometimes a dirty gray.
I have already explained the proper method of using the spatula. It reveals in all cases, sometimes best during retching, the epiglottis, and in many cases the ary-epiglottic folds. With the finger these parts can be touched, and all the more easily when they are swollen; but great care must be exercised to avoid provoking by digital examination a suffocative paroxysm. When felt by the finger the peculiar elasticity or fluctuation present is unmistakable.
PROGNOSIS.—Laryngeal oedema is always a very dangerous condition—in a chronic case less so than in an acute one. The prognosis depends largely upon the causative or accompanying disease. The more local the oedema and the more promptly medical, and in most instances surgical, aid can be had, the more favorable is the prognosis, though uncertain even then. Sometimes a rapidly fatal attack supervenes in a mild, chronic, or apparently convalescing case. In abscess formation it is generally favorable unless the underlying disease makes it the reverse.
TREATMENT.—Antiphlogistic treatment of every sort has been recommended against this dread disease. Its frequently rapid course usually necessitates primarily topical measures. Even fifty years ago, when bleeding and tartar emetic were in vogue, Ryland entirely discountenanced these, and said: "Our chief reliance must be placed on the local detraction of blood by means of a large number of leeches applied in the vicinity of the larynx; on the use of blisters, which should never be put on the front of the neck, as their operation will interfere with the subsequent performance of tracheotomy should such a step be necessary, but on the back of the neck or the upper part of the chest; and on the internal administration of large doses of calomel, which, either by their purgative effect or by their specific action on the general system, tend to check the inflammation in the glottis and to promote the absorption of the effused fluids. These remedies can only be of use during the early stages of the disease, and experience shows but too plainly that even then we have far more reason to anticipate failure than success."
Many years ago it was proposed to catheterize the trachea for the purpose of allowing air to reach the lungs in this and other diseases in which the larynx is obstructed; and more recently Hack has shown the great benefit of using, under sight by means of the laryngoscopic mirror, Schrötter's dilating hard-rubber tubes in acute as well as chronic laryngeal oedema. According to him, they do good not only symptomatically, but also curatively.
Furthermore, we can employ, under the guidance of the mirror or of the finger, scarifications of the infiltrated structures by means of the laryngeal lancet, or in its absence of a long bent, sharp-pointed bistoury covered, except for a quarter of an inch or so from its point, with adhesive plaster. (For the epiglottis the ordinary gum lancet will often do.) An abscess is opened in the same way. When the bleeding following scarification is excessive we use ice internally or externally, or both; when bleeding is insufficient, steam inhalation, hot fomentations, etc. To promote absorption we make topical applications, either before or certainly after the scarification, of a saturated solution of iodoform in sulphuric ether (drachm ij ad ounce j), or of a strong watery solution of silver nitrate (scruple ij–drachm j ad ounce j). Astringents, especially tannin and alum, applied in the form of spray to parts that cannot otherwise be reached, are advisable; and antispasmodics and narcotics (potassium bromide and morphine) should not be omitted in cases complicated with muscular spasm, etc. The internal administration of fluid extract of jaborandi in drachm doses or the hypodermic injection of pilocarpine is highly lauded as promoting absorption; also diaphoretics, purgatives (salines and croton oil), etc. From the beginning the patient's general functions must be regulated and his strength supported by tonics and nutritives, and any underlying disease amenable to treatment must of course be attended to. The slow swallowing of pieces of ice is often of great benefit. In every case that does not visibly improve by the vigorous carrying out of the treatment hitherto detailed, especially the catheterization by means of Schrötter's tubular dilators, the ultima ratio—viz. tracheotomy, particularly inter-crico-thyroid laryngotomy—must be resorted to without waiting until the patient has lost much ground by the impediment to respiration. One of the lessons taught us by pathological investigation is that epiglottic, supraglottic, and glottic oedema does not extend beyond the upper surface of the vocal bands: therefore, while in infraglottic oedema, and when the two conditions supraglottic oedema and infraglottic coexist, tracheotomy should be performed, in the other cases the air-passage should be opened by introducing a tube through the inter-crico-thyroid membrane. This operation is, especially for the general medical practitioner, much easier, safer, and quicker of performance, and answers in those cases all purposes. This important lesson is not heeded by any of the recent authors on the subject. Indeed, Cohen expressly says: "The trachea is to be opened in preference to the larynx, as being at a greater distance from the seat of the disease and less liable to involvement, as well as for the reason that the disease occasioning the oedema may be extending low down in the larynx, and therefore exist at the very point usually selected for laryngotomy." Supraglottic oedema does not extend to the region of the inter-thyro-cricoid membrane, and the tube may therefore safely be there introduced.
Perichondritis and Chondritis of the Larynx.
DEFINITION.—Inflammation of the laryngeal perichondrium and cartilage.
SYNONYMS.—Phthisis laryngea of the older authors, Laryngitis affecting the cartilages, Deep-seated ulcerative laryngitis, Caries cartilaginum laryngis, Vomica laryngis, Perichondric laryngeal abscess, Necrosis laryngis. (Some of these names refer to the product or terminal stage of the disease.)
ETIOLOGY.—Laryngeal perichondritis and chondritis occur either as idiopathic or as symptomatic or secondary affections. Even the former, caused by so-called catching cold or exposure to cold and wet while the system is in a state of lowered vitality, may have a septicæmic basis; it is much more rare than the secondary. Rühle has remarked that arytenoid perichondritis may probably sometimes start in the crico-arytenoid articulation, and in an instance which has come under my observation this certainly seemed to have been the case. Authors state that occasionally the inflammation commences in the cartilaginous tissue itself, instead of in its investment; this is hardly conceivable. Perichondritis must always precede chondritis, but it always causes the cartilage to become involved in the morbid process. Quite often perichondritis and chondritis constitute an extension of a particular ulcerative disease of the mucous and elastic membranes. In the great majority of cases the causes are tuberculosis, syphilis, diphtheria, cancer, lupus, typhus and typhoid fever, small-pox, or else traumatic occurrences, especially suicidal throat-cutting, decubitus or other pressure upon the part—as, for instance, the frequent introduction in an aged subject of the oesophageal sound observed by Ziemssen, and overstrain of the voice alleged by Flormann. At least three cases are reported (viz. by Porter, Lawrence, and Eppinger) in which the disease has been ascribed to the administration of mercury, and Graves and Stokes remark that in broken-down constitutions, where large quantities of mercury have been used, chronic laryngitis is very apt to terminate in ulceration of the cartilages.
The disease occurs oftener in men than in women, and oftener between the twentieth and fortieth years than at any other age.
SYMPTOMATOLOGY.—I distinguish three stages of laryngeal perichondritis and chondritis—viz. the inflammatory, suppurative, and necrotic. The symptoms of the first stage are obscure: the main one is pain, usually of a boring, burning character, localized according to the precise cartilage affected, which is increased by functional or other movement of the part and by pressure from the outside. To the pain there are gradually added—also depending somewhat upon the precise seat of the inflammation—cough, dysphonia, and dysphagia. In cricoid perichondritis—especially when, as is generally the case, the posterior surface of the plate of the cricoid cartilage is affected—there is sometimes inflammatory reddening of the pharyngeal mucous membrane which may extend upward to the palate. Inflammatory swelling of some part of the cartilaginous framework may be recognizable in the first stage of the disease by means of the laryngoscope.
The suppurative stage is attended with more swelling of the part affected, due to accumulation of pus and to collateral oedema. Pain, dysphagia, or dysphonia, and sometimes irritative, harsh cough may be much augmented; but, above all, dyspnoea now appears, which sometimes so rapidly increases that the patient dies asphyxiated unless tracheotomy is performed.
During the necrotic stage the symptoms of laryngeal stenosis sometimes persist, and sometimes cease with the expectoration of quantities of pus containing possibly a part, and occasionally the altered whole, of the affected cartilage: with continued purulent expectoration the patient's strength fails, the breath becomes very fetid, and hectic fever and death may supervene.
Swelling of cervical lymphatic glands, though by no means always present, has been observed in the early and sometimes only in the later stages of the disease.
The course of the disease, whether idiopathic or secondary, is either acute or chronic. It tends either toward abscess-formation, which predominates, or toward new growth of tissue; for a time sometimes the one, sometimes the other occurs, and, as a rule, during the former the process is more acute, and during the latter more chronic: the proliferated tissue, after being produced, may break down and increase the amount of pus. When acute, the three stages of the disease follow each other rapidly, if, indeed, the third be not cut off by the death of the patient. When chronic, the pus collected is very apt to burrow and to make fistulous passages and openings internally and externally. At various points also perichondric hypertrophies, ecchondroses, and exostoses are apt to occur.
The inflammatory stage can terminate by more or less complete resolution, though usually some enlargement of the cartilages permanently remains; recovery can also take place in the later stages, and leave deformities and produce cicatricial contractions.
PATHOLOGY AND MORBID ANATOMY.—The perichondrium of the larynx is diseased comparatively oftener than that of any other region of the body; which, aside from other causes, is partly due to the fact that the laryngeal cartilages become with increasing age normally vascular and ossified. The morbid process never affects at one time the whole of the cartilaginous framework of the larynx, and usually only one cartilage, or even only a limited portion of one cartilage, except in the case of the cricoid and arytenoid, which are sometimes together implicated. Perichondritis does not spread easily. The cricoid is most frequently affected, next the arytenoid, far less often the thyroid, and exceedingly rarely the epiglottis.
As already remarked, the inflammation of cartilage and perichondrium has a great tendency to suppuration—occasionally, though rarely, proliferation and hypertrophy; or, on the other hand, and more frequently if the inflammation is a slowly progressing one, the processes leading to ossification take place. The suppurative stage follows the inflammatory quickly unless the latter has been comparatively very slight. A great abundance of pus collects between the cartilage and its investing membrane. As the former is thereby denuded and separated from its nutritive vessels, it must become necrotic. Exfoliated pieces of cartilage are generally found in the abscess. Caries of adjacent tissues is apt to take place, and oedema of the surrounding connective tissue, and sometimes far-reaching destruction, before the perichondrium bursts or becomes destroyed over a large extent. In cricoid perichondritis, the plate mainly being affected, the abscess projects mostly toward the oesophagus and the trachea, or it points outwardly when the narrow portion is involved; the opening when the abscess has burst is frequently large, and shows a portion of the necrosed cartilage; sometimes there are a number of perforations. In arytenoid perichondritis the abscess bulges either into the interior of the larynx or into the adjacent pyriform sinus; bursting usually occurs at the posterior portions of the ventricular folds or near the posterior vocal process, and the undermined edges may disclose the dead cartilage. In thyroid perichondritis either the interior of the larynx, the pyriform sinus, or the outside of the neck is encroached upon.
In the course of the necrotic stage of the disease the laryngeal framework may cave in, and a stenosis be produced which may quickly put an end to the patient's life unless tubage—as explained under the head Oedema—or tracheotomy be performed. A loose piece of dead cartilage getting into the rima can produce the same fatal effect. Smaller or larger pieces of necrosed cartilage, sometimes partially or wholly ossified, have been expectorated, or, post-mortem, found lying in the respiratory passage, looking dirty-yellowish or blackish. Fistulous openings may take place in the larynx, pharynx, and in the skin covering these parts. Gaucher has reported an extraordinary case in which a perichondritic abscess of the thyroid cartilage had opened into the vertebral canal, as well as externally by the side of the sterno-cleido-mastoid muscle. If the perichondritis has followed deep-going ulcerative destruction of the mucous membrane, the perichondritic abscess bursts more easily, and less burrowing of the pus usually takes place.
In the rare termination of healing of the necrotic stage of perichondritis the loss of cartilage-substance is supplied by connective-tissue granulation emanating from the perichondrium. Cohen has reported a case in which there was apparently a reproduction of the whole cricoid cartilage, the necrosed original one remaining in the interior of the larynx as a foreign body.
Just as laryngeal stenosis is the grave danger during the continuance of the disease before the perichondritic abscess has opened from its protrusion into the laryngeal cavity, together with the accompanying oedema, and from the undermining of soft parts by burrowing pus, and after the abscess has opened from exfoliated pieces of cartilage blocking the interior, or, when eliminated, from caving in of the laryngeal framework, so laryngeal stenosis is the grave consequence of the disease from remaining deformity, cicatricial contraction, ankylosis of the crico-arytenoid articulation, etc. An open perichondritic abscess may also lead to extensive gangrenous destruction, and occasionally to subcutaneous emphysema.
Under the microscope the first stage of perichondritis is marked by the appearance in the fibrous basis-substance of the perichondrium of more or less coarsely granular corpuscles, the so-called inflammatory corpuscles. As to their origin, it is well known that Virchow taught that they are produced by the enlargement, division, and subdivision of the connective-tissue corpuscles, while Cohnheim claimed that they are nothing but emigrated colorless blood-corpuscles: in point of fact, most of them arise from the liberation of the living matter contained in the basis-substance, by the liquefaction or melting out of the non-living ingredient, and the increase and division of this matter into medullary or inflammatory corpuscles which constitute the so-called inflammatory infiltration. So long as the corpuscles remain connected by filaments of living matter, the inflammatory process may terminate by a new formation of basis-substance in hyperplasia—i.e. in the new formation of connective tissue. When, on the contrary, the inflammatory corpuscles are torn apart and become suspended in a liquid exudate, they constitute pus, and then the termination of the inflammatory process is in suppuration; that is to say, usually in an abscess.
The perichondrium and cartilage are normally so closely connected that the one tissue passes gradually into the other without definite boundary-line, and the cartilage participates in the inflammatory process by a liquefaction of its basis-substance, reappearance of the living matter therein contained, and the formation of more inflammatory corpuscles. So long as the inflamed perichondrium remains in living connection with the cartilage, both tissues may participate in the new formation of a dense connective tissue, and hyperplasia be the result of the perichondritis and chondritis. Should, on account of suppuration at the boundary of the cartilage, the vascularized portion of the perichondrium become detached, the cartilage, being itself devoid of blood-vessels, will become dead. Its corpuscles will shrivel, and together with the lifeless basis-substance become disintegrated. Pieces of necrotic cartilage may be found lying in the surrounding pus, and, though usually chondritis has preceded the necrosis, the latter may ensue without previous change of the cartilage tissue, especially if the perichondritis runs its course to suppuration rapidly; but in every case suppurative perichondritis precedes necrosis of the cartilage.
After the elimination of necrosed portions cartilage is as a rule replaced by newly-formed dense fibrous connective tissue. Some clinically-observed cases, aside from the remarkable case of Cohen already mentioned, indicate, however, that, exceptionally, new formation of cartilage may occur from hyperplastic perichondrium, in the same manner as new bone is sometimes formed from hyperplastic periosteum after osseous necrosis.
DIAGNOSIS.—The inflammatory stage may be suspected, rather than positively recognized, from the peculiar pain if the laryngoscope (or, in the rare case of thyroid perichondritis, palpation) reveals enlargement of a part of the cartilaginous structure without much injection of the mucous membrane. The presence of other symptoms mentioned, and in the case of cricoid perichondritis the localized pharyngeal reddening, make the diagnosis more probable. During the suppurating and necrotic stages the diagnosis becomes certain from the symptoms I have described, especially expectoration of fragments of necrosed cartilage, together with direct examination. The laryngoscope may show the abscess; sometimes the finger or a probe can detect fluctuation, and frequently through an opening the probe detects the necrosis. The movement of one or both vocal bands may be affected either mechanically from purulent accumulation, or from articular ankylosis, or from interference with muscular attachments or action, or with innervation. In my hand, and in that of others, a probe introduced through an external fistula has been seen in the larynx; others have been able to inject colored fluid and find it in the interior.
PROGNOSIS.—Except in slight cases death is more apt to take place than recovery. If tracheotomy has saved the patient from impending death, ultimate prognosis is still unfavorable in severe cases. In idiopathic, traumatic, and syphilitic cases the prognosis is of course better than in others in which we have to face grave dangers of the underlying disease as well. The remaining laryngeal stenosis after recovery makes the prognosis bad as to the doing away with the tracheotomy-tube, although it is far more favorable at the present day than it was previous to Schrötter's success with dilating measures.
TREATMENT.—Throughout the disease the patient's general health and strength must be carefully attended to, tonics and stimulants used according to circumstances, and the underlying condition of secondary perichondritis, such as syphilis, etc., treated secundum artem. Locally, the treatment during the first stage must be antiphlogistic, by leeches, ice, etc., and soothing, especially by inhalations. Afterward, abscesses must, if accessible by means of the laryngoscope, be opened. Artificial feeding, through either an oesophageal or a rectal tube, may become necessary. Schrötter's hard-rubber tubes may be inserted to conduct air to the lungs, but tracheotomy, not laryngotomy, must be performed if, in spite of this tubage, suffocation threatens.
The methodical dilatation of post-perichondritic laryngeal stenosis requires special bougies, catheters, hard-rubber tubes, pewter plugs, and dilators which are not to be found in the ordinary armamentarium of a medical practitioner; but the proper and frequently successful use of these can be acquired with patience and perseverance when a case of the kind presents itself for treatment.
Chronic Laryngitis.
DEFINITION, SYNONYMS, AND CLASSIFICATION.—Under the name chronic laryngitis are brought together a number of different diseases of the larynx which have the character in common that they are more or less inflammatory and chronic in their course. The various conditions of chronic inflammation of the mucous membrane (chronic laryngeal catarrh) prominently belong to this category, but the chronic inflammation of every other constituent tissue of the larynx, except cartilage and perichondrium, is included.
The synonyms refer mostly to individual etiological and other factors not applicable to all cases, as clergymen's laryngitis, phthisical laryngitis, and many of the designations of different classes.
Chronic laryngitis frequently involves more than one tissue, but usually one prominently. Histologically, the following kinds of chronic laryngitis have been distinguished: viz. catarrhal, when simply or principally the mucous membrane is affected; granulous or glandular, when the muciparous glands; submucous or parenchymatous, when the connective tissues underneath the mucous membrane are prominently implicated; and muscular, when there is chronic inflammation of the muscular tissue. According to the seat, there will be supraglottic, glottic, and infraglottic chronic laryngitis. There have also been described atrophic, hypertrophic, and polypoid chronic laryngitis; dry and blenorrhoeic or hypersecreting chronic laryngitis; simple, fetid or ozænic, and ulcerative; phlebectasis laryngea, trachoma, etc.
ETIOLOGY.—Chronic laryngitis is caused in many ways. Frequently it follows uncured or neglected acute laryngitis. It is apt to occur in persons whose avocations or habits lead them to strain or otherwise abuse their vocal organ, to work in an impure or irritating atmosphere, or to use tobacco or alcohol excessively; and it may depend upon or be an extension of chronic inflammation of either the naso-pharyngeal or tracheo-bronchial mucous membrane. Secondarily, it accompanies all long-continued laryngeal affections, such as phthisis, syphilis, lupus, etc. Males suffer more often than females, and middle-aged persons more often than either children or the very old. Boys at the time of puberty are liable to become affected.
SYMPTOMATOLOGY.—The diseases comprised under the collective name of chronic laryngitis give rise to various symptoms, of which the chief are morbid sensations in the region of the larynx and alteration of the voice. Unless ulceration have occurred, the morbid sensations hardly amount to pain, except on acute exacerbation from catching cold or after long-continued use of the voice. They consist in a sense of dryness or of pressure, in a tickling or in an unnatural feeling that cannot be definitely described in words. Though not acute, they are sufficient to make the patient constantly conscious of their existence and to induce fruitless efforts at clearing the throat, etc. The alteration of the voice varies from occasional unsteadiness or veiling, or a loss of power or purity of tone, to different degrees of hoarseness, dysphonia, and even aphonia. In singers and public speakers the disease interferes sometimes with professional vocal efforts only, ordinary conversation not being affected. The voice is best, sometimes worst, after a night's rest, and in either instance changes after moderate use for worse or better as the case may be; but long-continued exercise is always harmful. The voice is comparatively easily fatigued, and then the vocal organ becomes positively painful.
In addition to the two chief and constant symptoms there are others that may or may not be present, and which sometimes assume even greater prominence than the modification of the voice. Thus, secretion, which in most cases is very slight, glassy grayish, and viscid, is occasionally very abundant, yellowish, or darkish, or more rarely still mixed with streaks of blood and in clumps, though not sticky or dried into scabs, and is sometimes so fetid that the patient's breath is exceedingly malodorous. Cough, which in most cases is either absent or comparatively trifling, barking, or hacking, occasionally is the most troublesome of all the symptoms. Dysphagia is sometimes present even in simple or mild cases. In severer cases, in the later stages, especially in syphilitic and phthisical chronic laryngitis, swallowing becomes painful and difficult, or even impossible. Dyspnoea occurs only from accumulations of phlegm in the larynx, and is then lessened after expectoration, or it may depend upon the diminished lumen of the laryngeal cavity on account of thickening of the walls, as it is especially apt to do in subglottic chronic laryngitis, or on account of so-called polypoid hypertrophies in simple cases, gummata or cicatricial tissue in specific cases, etc. Dyspnoea may become so urgent as to require tracheotomy.
PATHOLOGY AND MORBID ANATOMY.—In catarrhal chronic laryngitis there is congestion of the mucous membrane, dilatation of the blood-vessels, and altered secretion. The mucous membrane becomes, as a rule, hypertrophied, tougher, and more firmly connected with the subjacent tissues. Laryngeal venous congestion (so-called phlebectasis laryngea) is occasionally, though rather rarely, met with; and still more rare is a hemorrhage from the surcharged vessels in chronic cases. In granular or glandular chronic laryngitis—i.e. when the muciparous glands are prominently involved in the inflammatory process—they form elevations, making the surface uneven, and the tissues become tenser and more compact. When the submucous connective tissue takes much part in the process the hypertrophy is still greater, and not only may the lumen of the laryngeal cavity become greatly diminished, but projections of various lengths (the so-called cellular polypi and papillary excrescences) are apt to occur. The objective term tuberosa is sometimes added to laryngitis or to the designation for inflammation of a portion of the larynx; as, for example, that of the vocal bands—viz. chorditis tuberosa, when small whitish, tumor-like elevations occur. These, especially on the vocal bands, where they have been described by Tuerck, Elsberg, Cohen, and others, are also called trachomata. In cases to which the name muscular chronic laryngitis is given the muscular tissue has been found prominently hypertrophied. Moura Bourillou has recorded a case in which the striated fibres of the posterior crico-arytenoid muscle were converted into fibrous tissue. In many of the common cases of catarrhal chronic laryngitis the alteration of the voice depends upon paralysis of the muscles—especially the thyroid arytenoid and the arytenoid—directly caused by the transmitted inflammation and by thickening of the overlying mucous membrane. In fetid chronic laryngitis there is usually found excoriation of the mucous membrane, and atrophy. That erosions—i.e. superficial ulcerations extending no deeper than the epithelial layer—frequently occur in the course of catarrh is admitted by everybody, but much unnecessary discussion has been indulged in concerning the question whether deeper ulcerations of the mucous membrane can ever take place under these circumstances. It has been insisted upon that catarrhal ulcerations never occur. This is a mistake, but it is true that catarrhal ulceration is rare unless the patient is greatly debilitated or cachectic. Ulcerative chronic laryngitis in the majority of cases depends upon some cachexia—i.e. tuberculosis, syphilis, lupus, lepra, etc.
Tuberculous chronic laryngitis—laryngeal phthisis proper—frequently accompanies pulmonary consumption. Usually it follows, but occasionally precedes, the latter. Unquestionably, it also occurs, though rarely, without any disease in the lungs. Anæmia of the laryngeal mucous membrane is present from the first, and usually persists throughout. There is a low form of inflammation, swelling of the tissue, and then ulceration, the ulcers being at first small, and afterward coalescing to form larger ones. Much destruction may take place, and more or less oedema is always present. Paralysis of some of the interior laryngeal muscles may also occur, depending alike upon anæmia and oedematous infiltration of the muscular substance, or upon compression of the nerve-tracts by enlarged lymphatic glands (most frequently on the right side) or upon involvement of the nerves—pleuritic adhesions, tuberculous deposits, etc.
Syphilitic chronic laryngitis is a local manifestation occasionally of hereditary, but usually of acquired, syphilis. It may vary from a slight erythematous condition of the mucous membrane to intense inflammatory thickening or destructive ulceration, may be accompanied by laryngeal oedema and pericarditis, and may lead to dangerous adhesions, cicatrizations, and stenosis. The chronic laryngitis occurring in lupus and lepra and in malignant diseases of the larynx partakes of the character of these processes, and is accompanied by their peculiar thickenings, tuberosities, granulations, and ulcerations.
DIAGNOSIS.—Chronic alteration of voice, local morbid sensation, and other symptoms mentioned may lead us to suspect the presence of chronic laryngitis, but are insufficient for diagnosis without mirror examination. The diagnosis can be positively made only by means of the laryngoscope, and even by this means requires care. It is of the utmost importance that the physician make himself perfectly familiar with the appearance of the healthy larynx by the particular illumination he uses for examining patients.
A very able laryngoscopist, Carl Michel of Cologne, confesses6 that he has many times diagnosed chronic laryngitis when none existed, and explains that with inadequate illumination the contours of the small vessels run into one another and make the whole surface which they traverse appear red. In simple chronic laryngitis the redness has a somewhat livid look; in syphilitic chronic laryngitis it is darker and more angry-looking; in phthisical cases it is duller, even though the mucous membrane be congested, while usually it is pale. In both the latter diseases the swelling is greater, the natural contour of the parts more changed, and destruction more imminent than in the simple chronic laryngitis. When oedema is present there is a peculiar transparent or translucent appearance. In subglottic chronic laryngitis, especially when much hypertrophy has already taken place, the color is often quite light grayish instead of red.

Phlegm found in the larynx may have come from the bronchial tubes or the trachea; when it is cleared away by cough or otherwise, the larynx may prove to be unaffected. In all cases of suspected secondary chronic laryngitis, phthisical, syphilitic, etc., the state of the lungs and whole respiratory tract, as well as the general health in every respect, hereditary tendencies, and past diseases, must be carefully inquired into.
PROGNOSIS.—The prognosis of chronic laryngitis is good as to life except in broken-down constitutions, neglected exacerbations, and grave underlying affections; but, even with these exceptions, it can be said to be favorable as to cure only with expert local treatment and if no severer tissue-alterations, usually hypertrophic, have as yet taken place. If the latter have taken place—especially if the submucous tissues are prominently involved—the organ can seldom be restored to perfect integrity. For persons in ordinary vocations and situations in life the recovery that can generally be secured may be entirely satisfactory, but more exacting demands on the speaking and singing voice require special measures, including hygienic precautions, to be carried out carefully, and sometimes to be long continued.
BY J. SOLIS COHEN, M.D.
TREATMENT.—Whatever the grade or stage of a chronic laryngitis, the constitutional condition or proclivity of the patient always requires suitable hygienic, dietetic, and therapeutic management. The repair of regional or local morbid conditions may often be confidently entrusted to such constitutional measures; and it is only when these morbid conditions resist the influence of systemic treatment, or are of some special character obviously insusceptible to such influence, that topical medication or actual surgical procedure becomes requisite in addition. The accessibility of the interior of the larynx to instrumental manipulation under laryngoscopic guidance offers great temptations for topical interference. The result is, that the diseased larynx is sometimes submitted to unnecessary, and even injurious, direct attack at the hands of a dexterous manipulator untrained in general practice, and consequently ignorant of the beneficial influence of purely constitutional measures upon many local morbid conditions. While it is highly proper, therefore, to utter a few words of caution, it is equally proper to assert that many local conditions are entirely beyond the control of systemic measures, and require topical treatment.
Constitutional Treatment.—Simple or catarrhal chronic laryngitis, unassociated with special diathesis, is often admirably influenced by the prolonged administration of some preparation of cubeb; the oleoresin being preferred by the writer in doses of from fifteen to twenty-five minims for the adult, three times a day on crushed sugar. This drug being eliminated in part by the bronchial tract, it seems especially adapted to exert upon chronic inflammatory conditions of the aërial mucous membrane that healing process which it is known to exert on mucous membrane elsewhere. Among other useful constitutional remedies from which similar service can be expected may be enumerated compound tincture of benzoin in doses of from thirty to sixty minims for the adult, three or more times daily; fermented infusion of tar or tar beer, several ounces daily; and petroleum mass, one to two grains for the adult, three or four times daily, with pulverized extract of glycyrrhiza in pill or capsule. In cases with deficient secretion ammonium chloride is indicated. In cases associated with impaired digestion, with excess of acidity, the prolonged use of alkaline mineral waters is advisable; preferably, if convenient, at their sources. In cases associated with chronic diarrhoea the mineral acids are indicated. Cod-liver oil, hydrated chloride of calcium, and preparations of iodine and of arsenic are useful in patients of the scrofulous diathesis. Iodoform, one grain for the adult, rubbed up with glucose or some other excipient, in pill or capsule, three times a day, is often useful in patients with the tuberculous diathesis. Specific remedies are required for syphilis. In like manner, any constitutional abnormality is to be systematically attacked.
The functions of skin, kidneys, and intestine are to be maintained as nearly normal as may be, or even a little in excessive action from time to time for derivative purposes. Abstinence is to be enjoined from all exposures or indulgences deleterious to the parts diseased; with as sparing a use of the voice as is compatible with ordinary domestic or social demands, and absolute rest for prolonged periods of days at a time whenever unusual demands have resulted in exacerbating the malady. Under such treatment many cases of simple catarrhal or glandular chronic laryngitis may get well, as has been intimated, without any special local measures.
Topical Treatment.—The difficulty of impressing patients with the necessity of submitting to these hygienic measures and to dietetic restrictions, and for avoidance of occupations or habits which favor or maintain the condition of chronic inflammation, renders topical treatment necessary in many instances. Direct instrumental medication requires the personal attention of the medical attendant. Medication by inhalation or insufflation may be entrusted to the patient or the nurse in most instances. In instituting a course of topical treatment several things must be taken into consideration, such as the condition of hyperæsthesia, hypersecretion, insufficient secretion, congestion, hemorrhagic infiltration, hemorrhage, hypertrophy of tissue or tissue-elements, erosion, fissure, ulceration, and excessive granulation. The first three of these furnish the clue to the nature of the home-treatment, the remainder to that required at the hands of the physician. The home-treatment is to be directed to keeping the parts clean and comfortable; the manipulation of the physician is to be directed toward overcoming special pathological conditions.
Should secretion be defective, alkaline sprays inhaled at regular intervals, for a few minutes at a time, tend to augment secretion and to facilitate the detachment of adherent mucus. For the purpose choice may be made of the following drugs in the proportion of about five grains to the ounce for the adult, dissolved in distilled water or tar-water, with the addition of a sedative when the parts are hyperæsthetic, or an opiate when they are painful: ammonium chloride, sodium borate, sodium bicarbonate, sodium chloride, sodium chlorate, sodium iodide, potassium iodide, potassium chloride. The spray should be propelled by means of compressed air, with what is known as the hand-ball atomizer, in preference to steam, the effect of which is too relaxing in most instances. A few drops of some aromatic or balsamic product will render the spray more agreeable in many instances. Should these agents fail, pyrethrum or jaborandi may be found more serviceable, in the proportion of from one to five minims of the fluid extract to the ounce of water.
Should secretion be excessive, astringents are indicated; and choice may be made from alum, five grains to the ounce of rose-water; tannic acid, two or three grains; zinc sulphate or zinc sulphocarbolate, two grains; lead acetate, two grains; ferric chloride, one grain; and silver nitrate, half a grain to the ounce. Personal supervision of the initial inhalations is requisite to ensure proper use of the spray. Whether the medicament is to be propelled directly into the larynx by means of a tube with a vertical tip to be passed beyond the tongue, or to be inhaled by efforts of inspiration from spray projected horizontally, will depend upon the skill of the individual using it. Hard-rubber spray-producers are furnished with series of tips, so that either method may be employed. When the horizontal tip is used, the instrument should be held some distance from the mouth, so that the spray may be deflected into the larynx by the act of inspiration. When the tube is placed within the mouth most of the spray becomes condensed upon the pharynx, and very little can be drawn down into the larynx. As metallic tubes are liable to become reduced by certain remedies—ammonium chloride, for instance—tubes of glass or of hard rubber are to be preferred.
Should a steam apparatus be employed, the patient should remain housed for half an hour after inhalation, except in very warm weather. In cases of hyperæsthetic mucous membrane the home inhalation of volatile remedies daily is often useful. Compound tincture of benzoin, camphorated tincture of opium, oil of pine, oil of turpentine, terebene, eucalyptol, creasote, carbolic acid, may be inhaled from a bottle containing hot water or from a special inhaler, a few drops of chloroform being advantageously added when there is a good deal of irritative cough. A few drops of the more pungent volatile substances, such as terebene, eucalyptol, and creasote, may be dropped on the sponge supplied with the perforated zinc respirator of Yeo of London, and the apparatus be worn for an hour or longer continuously. In cases with excessive secretion and in syphilis, ethyl iodide is indicated as a remedy appropriately administered by this method. When the parts are very irritable, a respirator of this kind or some similar contrivance, or a fold or two of woollen or silk gauze worn in front of the mouth and nose while in the open air, will often protect the tissues from too cool an atmosphere, and enable the patient to bear exposure with comfort.
Topical treatment of a more decided character being required, the physician usually chooses between powder and solution. Powders are usually propelled by a puff of air through a properly curved tube, whether from a rubber ball, a reservoir of compressed air, or the mouth. The mouth allows the most delicate and accurate application, but the mouthpiece should be protected by a valve from receiving a return current when the patient coughs. Solutions may be applied by means of pipette, syringe, brush, cotton wad, or sponge, according to indications. A fragment of sponge securely fastened to a properly-bent rod or pair of forceps is the safest and most effectual material for positive contact against a limited surface, and a brush the best for painting larger surfaces. The use of the cotton wad involves a slight risk of leaving a detached shred of fibre in the larynx, but renders the manipulation less unpleasant to the patient than the use of the sponge, and is less irritating to the mucous membrane. Spasm of the larynx is usually excited the first time that a medicinal application is made within it, and even death by suffocation has followed the incautious use of powerful agents. Hence strong solutions should not be used until the tolerance of the parts has been sufficiently tested by weak or innocuous ones. The remedies which have been employed topically for intra-laryngeal medication seem to include every available medicinal agent that could be mentioned, from rose-water to the incandescent cautery. The list of really useful ones is not very long. Those upon which the most reliance is placed by the writer comprise tannic acid (a saturated glycerite), zinc sulphate (thirty grains to the ounce of rose-water), and silver nitrate (forty to sixty grains to the ounce) in obstinate and protracted cases of simple chronic laryngitis; iodine and carbolic acid, singly or in combination (one grain or more to the ounce of glycerin), and chinoline tartrate or salicylate (five or more grains to the ounce), in cases attended with infiltration; iodoform (finely pulverized or in recent saturation in sulphuric ether) in ulcerative or proliferative tuberculosis; and iodoform and acid solution of mercuric nitrate (one part to ten or twelve of water) in progressive ulcerative syphilis resisting appropriate constitutional treatment. Other astringents in the simple varieties; resorcin in the glandular, hypertrophic, polypoid, and tuberculous varieties; chromic acid and incandescent metal in the circumscribed hypertrophic and in the polypoid varieties; and zinc chloride and copper sulphate in the syphilitic varieties,—proffer additional resources. These applications are to be made at intervals of one day or more, according to results. Hyperæsthesia and pain, whether of the larynx or of parts adjacent, can usually be subdued by the local anæsthetic effect of solutions of erythroxyline hydrochloride (2 per cent. or stronger) applied at intervals of a few hours, or even by the fluid extract or a strong aqueous infusion of the erythroxylon-leaves. Before the anæsthetic effect of this drug was known, morphine powder (one-eighth to one-fourth of a grain, alone or associated with tannin or with iodoform) or aqueous solutions of morphine salts and of aconite were employed to relieve pain and obtund sensitiveness. The oleate of morphine (2 to 4 per cent. solution) and the oleate of aconitine (2 per cent. solution) are similarly useful. Morphine, by its constitutional influence, is preferable to erythroxyline in some instances, though less prompt in its effects. Where ulcerative processes at the top of the larynx or thereabouts entail odynphagia, these preparations should be used before administering nourishment. The use of erythroxylon products may be entrusted to the nurse or to the patient with comparative safety. Morphine and aconite should be applied only by a medical attendant or an exceptionally skilled nurse. Before any medicinal curative or reparative agent is applied the parts should be thoroughly cleansed of suppurative and secretory products. This may be done with sprays of alkaline solutions—five or more grains of sodium borate or bicarbonate, for example—dissolved in pure water, in tar-water, or in an emulsion of coal tar. An excellent agent, especially in the presence of pus, is hydrogen dioxide, usually furnished in a 10-volume solution which should be diluted with two or more parts of distilled water. It is likewise disinfectant and gently stimulant to mucous membrane. The manipulations by the physician preparatory and medicatory should be performed laryngoscopically, otherwise the entire procedure must be haphazard.
Neoplasmata and fungous growths may require removal should they interfere with respiration. In the presence of stricture, surgical interference by tracheotomy may become requisite. Elsberg, according to the testimony of his assistant, Schweig, seems to have been particularly favorable to the performance of this operation in obstinate cases of ulcerative laryngitis of whatever character, and even in protracted non-ulcerative cases, for the purpose of securing physiological rest to the parts, although the procedure might not be indicated to relieve any embarrassment in respiration. The writer's experience in tracheotomy as a factor in producing rest has not been favorable, such a result being usually defeated by the cough so frequently following a tracheotomy, no matter how well-adjusted a tube may have been inserted. His recommendation, therefore, is limited to cases of embarrassment to respiration due to stricture or constriction unamenable to intra-laryngeal interference.
Morbid Growths of the Larynx.
DEFINITION.—Neoplastic formations, benign and malign, in the interior of the larynx, in its cartilaginous framework, in its investment-tissues, or upon the exterior of the organ.
ETIOLOGY.—Inflammation of the mucous membrane, local irritation or injury, ulceration, cell-proliferation, and excessive granulation seem to be the exciting causes of benign neoplasms. They follow on laryngitis, whether catarrhal, syphilitic, tuberculous, exanthematic, toxic, or traumatic. They are quite common, so to speak, several thousands of cases being on record, and as many or more probably being unrecorded. Heredity does not seem to play any special part in their production. They are occasionally congenital, and may be developed at any age; but they are encountered the most frequently in subjects between the ages of thirty and sixty years, probably because of the greater exposure to laryngitis attending the activity incidental to the prime of life. Males are affected far more frequently than females, probably on account of greater exposure to sources of laryngitis. Benign growths are sometimes followed by malign growths in recurrence, and are sometimes converted into malignity by irritation, whether physiological, mechanical, or instrumental. Malign growths are attributed to cold, chronic laryngitis, and traumatism as the initial exciting causes. Butlin suggests a cryptogamic origin. They are far more common in males than in females, and occur chiefly between the ages of twenty-five and seventy, but they have been noted as occurring exceptionally much later, and even as early as the first year.
PATHOLOGY AND MORBID ANATOMY.—By far the greater number of laryngeal morbid growths belong histologically to the category of benign neoplasms, but the important location they occupy often renders them clinically malign. By far the greater number of benign growths are papillomas, perhaps fully two-thirds, although Elsberg has reported that but 163 instances were papillomas out of 310 seen in his own practice.7 This has been an exceptional experience. Then we have fibromas, myxomas, adenomas, lymphomas, angeiomas, cystomas, ecchondromas, lipomas, and composite neoplasms. Laryngeal morbid growths, too, occasionally undergo the fatty, colloid, or amyloid degenerations. Papillomas are frequently multiple, and most frequently sessile, but the other benign neoplasms are most frequently single and are more often pedunculated. All this class of morbid growths affect the anterior half of the larynx more than the posterior. They are most frequent on the vocal bands or very near to them, although they may occupy any portion of the larynx. They vary in size from the smallest protuberance to a bulk sufficient to block up the cavity of the larynx and even project above it. The dimensions of the greater number of papillomas vary from the size of a pea to that of a small mulberry. Other benign neoplasms rarely reach the bulk attained by papillomas.

Malign growths are far less common than benign ones. They comprise both sarcomas and carcinomas. Sarcomas occur in the varieties of spindle-celled, round-celled, giant-celled, mixed-celled, fibrosarcoma, lymphosarcoma, and myxosarcoma. Some attain only the size of small beans, and few exceed the size of a pigeon's egg. The majority of them are primary growths. Most of them originate in the interior of the larynx, whence they may extend by contiguous infiltration, even penetrating the laryngeal walls. The vocal band and the ventricular band are the most frequent seat. The epiglottis is a common seat. These growths appear either in irregular, smooth, spheroid masses, or nodulated, mamillated, and dendritic. They are much the more common in males, and occur chiefly in subjects between the ages of twenty-five and fifty. Their growth is slow for a year or more, and then becomes more rapid.
Carcinoma is much more common than sarcoma. It is most frequently primary, and primarily limited to the larynx, but occurs likewise in extension of carcinoma of the tongue, palate, pharynx, oesophagus, or thyroid gland. It rarely extends to the oesophagus or penetrates the laryngeal walls.
Squamous-celled carcinoma or epithelioma is the commonest variety, large spheroidal-celled or encephaloid being much less frequent, and small spheroidal-celled and cylindrical-celled occurring still more rarely. Intrinsic laryngeal carcinoma is usually unilateral at first, and most frequently in the left side. Its most frequent seat is at the vocal band. It rarely occurs below this point, and when it does, as in the five cases analyzed by Butlin,8 it seems to be at some point just beneath. Extrinsic laryngeal carcinoma usually begins in the epiglottis, and sometimes occupies that structure only. It may begin in a cicatrix in the skin.9 Carcinoma is the more common in males, chiefly in subjects between the ages of fifty and seventy. It has occurred within the first year, at three years, and as late as at eighty-three years. Carcinoma is liable to extend by infiltration of tissue and destroy all the contiguous and overlying tissues, so that it may extend into the pharynx or even externally; the large spheroidal-celled variety presenting the most frequently progressive ulceration into contiguous tissue, and the squamous-celled, intrinsic ulceration. Hemorrhage is frequent. Perichondritis, abscess, necrosis, and fistula take place in old cases.

SYMPTOMATOLOGY.—Small growths in localities where they neither provoke cough nor interfere with voice or respiration may run their course for a long time without giving rise to any symptoms at all. Growths of larger size, pedunculated growths, and growths located upon important structures give rise to interference with voice, respiration, or deglutition as may be—to cough, and even to pain. Dysphonia is due to mechanical interference with vibrations of the edges of the vocal bands; aphonia, to mechanical interference with their approximation; diphthonia, to mechanical interference at an acoustic node. These manifestations may be permanent or intermittent. Dysphonia is one of the earliest symptoms of carcinoma, and is usually continuous for a number of months before any other indication. Aphonia in carcinoma is often due to nerve-lesion. Dyspnoea is due to some considerable mechanical occlusion of the respiratory tract, whether by the growth itself or in consequence of oedema or of intercurrent tumefaction. It is inspiratory rather than expiratory, and subject to aggravation at night. As with the dysphonia, it varies with the size, location, and mobility of the growth and the position of the head and neck. It may be intermittent or permanent; be slight or severe; or it may terminate in apnoea by spasm, by mechanical occlusion of the calibre of the larynx, or by impaction of the growth at the chink of the glottis. Marked encroachment on the breathing-space is not accompanied with as marked dyspnoea as in acute processes, the parts seeming to acquire tolerance during the slow growth of neoplasms.
Dysphagia is due to a growth at the top of the larynx or on some portion of its pharyngeal surface. It is quite frequent in carcinoma, preceding dysphonia in the extrinsic varieties. It may be associated with regurgitation of food, drink, or saliva into the larynx, provocative of paroxysms of suffocation. Cough is due to growths which project from the vocal bands or press upon them, or to hemorrhage or accumulation of secretory or suppurative products. Hemorrhage, cough, and expectoration of bloody and fetid masses are indicative of carcinoma. Pain is usually due to intercurrent conditions. Aches in the part and sensations of the presence of a foreign substance are more frequent. Intense pain is exceptional in benign neoplasmata; it is often an early symptom in carcinoma, in which it is apt to radiate toward the ears and along the neck. Epileptic seizures and vertigo are sometimes occasioned by reflex influence. Exceptionally, large growths may produce change in the external configuration of the larynx. The general health is not much involved in benign growths, unless they interfere seriously with important physiological functions. Impaired health is far less manifest in sarcoma than in carcinoma. Emaciation, pyresis, and marasmus eventually occur as constitutional manifestations of malign growths.
DIAGNOSIS.—Laryngoscopic inspection usually reveals the growth and furnishes the best means of diagnosis. Intra-ventricular and subglottic growths may elude detection. Palpation is sometimes available, especially with children. Palpation with probes under laryngoscopic inspection is sometimes requisite to determine the mobility of a growth, its form and seat of attachment, and even its size. It seems, too, to discriminate a neoplasm from an eversion of a ventricle. While the histological character of a growth cannot be definitively decided by laryngoscopic inspection, the varieties present a series of characteristics sufficiently pronounced for approximative discrimination. Papillomata are often multiple, usually sessile, and usually racemose or dendritic. Some are white, but the majority are red, and the tinge varies from one extreme of the tint to the other. Some are as small as the smallest seeds; most of them have a bulk varying from that of a pea to that of a berry; some of them are so extensive as to appear to fill the larynx or even project above its borders. They are far the most frequent in the anterior portion of the larynx, and are often located upon a vocal band. Fibromata are most frequently single, smooth and pedunculated, and red. Some are white or gray. Some are vascular. When fully developed they vary in size from small peas to large nuts. They are more frequent upon a vocal band. Their development is slower than that of papillomata. Myxomata are usually single, smooth, pyriform, and pedunculated. They are usually red or reddish. Their ultimate size varies from that of grains of rice to that of Lima beans. They are most frequent at the commissure of the vocal bands. Angeiomata are usually single, reddish or bluish, vary in size from that of small peas to that of berries, and are most frequent on the vocal bands. Cystomata are usually globular, sessile, translucent, and white or red. They are most frequent in a ventricle or on the epiglottis. Their size varies from that of hempseed to that of peas. Ecchondromata are usually developed in the posterior portion of the larynx. Other benign growths are very rare, and do not seem to present special features for recognition by laryngoscopic inspection. Sarcomata are usually present as sessile, hard, well-circumscribed growths, smooth or lobulated. Some are dendritic on the surface, but not to the extent noticed in papillomata, and their location at the posterior portion of the larynx would suggest their true character, for papillomata rarely occupy this position except in tuberculosis. Superficial ulceration occurs in some cases, but is not extensive. There is no peculiarity in the color of the mucous membrane, which may be paler or redder than is normal. The lymphatic glands are not involved.10 Carcinomata present first as diffuse tumefactions in circumscribed localities, gradually undergoing transformation into well-formed growths, then nodulation, and then ulceration. Meanwhile, especially in extrinsic varieties, the submaxillary and the cervical lymphatic glands become successively involved and tumefied. Squamous-celled carcinoma becomes pale, wrinkled, and nodulated, and sometimes dendritic. Large spheroidal-celled carcinoma becomes nodulated, dark, and irregularly vascular, and finally ulcerated, perhaps at a number of points. In the ulcerative stage of carcinoma of the epiglottis and of the interior of the larynx discrimination is requisite from syphilis and from tuberculosis. In all cases of doubt as to malignancy, laryngoscopic inspection should be supplemented by microscopic examination of fragments detached for the purpose. The early detection of sarcoma may lead to surgical measures competent to save life—a remark applicable, perhaps, in a far more limited degree to intrinsic carcinoma.

PROGNOSIS.—The prognosis is usually good in benign growths submitted to proper surgical treatment. Left to themselves or treated medicinally, the prognosis is bad both as to function and to life. Such growths are occasionally expectorated after detachment during cough or emesis. Some occasionally undergo spontaneous absorption. Some remain without change for years. Most of them enlarge and compromise life as well as function. Recurrence occasionally follows thorough removal, and this recurrence is occasionally malign in character. Repullulation frequently follows incomplete removal. The prognosis is favorable in sarcomata, provided thorough eradication can be accomplished by surgical procedure. Incomplete removal is followed by repullulation or recurrence. Unsubmitted to operation, sarcoma will destroy life either mechanically by apnoea or physiologically by asthenia.
The prognosis is unfavorable in carcinoma. Recurrence takes place as the rule despite the best devised resources of surgery. Intrinsic carcinoma offers some hope of success to the surgeon; extrinsic carcinoma, little if any. Life is shortest in the large spheroidal-celled, and longest in the small spheroidal-celled variety, other conditions being equal. Death may take place by apnoea or asthenia, as in sarcoma, or by hemorrhage, collapse, or pyæmia. Submitted to tracheotomy at the proper moment in cases in which death is threatened by occlusive dyspnoea, life is prolonged and suffering mitigated. The fresh lease of life is longest in the squamous-celled variety.
TREATMENT.—The essential treatment is surgical, and to surgical works the reader must be referred for details. Suffice it to say that when a benign growth is small and does not embarrass respiration, it need not be attacked at all, unless its interference with the voice deprives the patient of his means of livelihood. The majority of benign growths are accessible to instruments passed through the mouth. Some require external incision into the larynx, whether partial or complete. The intra-laryngeal procedures in vogue include cauterization, both chemical and by incandescence, incision, abscission, crushing, brushing, scraping, and evulsion. According to the character and location of the growth, direct access from the exterior is practised by infra-hyoid pharyngotomy, by partial or complete thyroid laryngotomy, mesochondric laryngotomy, cricoid laryngotomy, complete laryngotomy, laryngo-tracheotomy, or tracheotomy, as may be indicated.
The thorough eradication of sarcomata usually requires a direct access by section of the thyroid cartilage or even of the entire larynx. This procedure failing or appearing insufficient, partial or even complete laryngectomy may be necessary. Temporizing is of no avail.
The treatment of carcinoma is palliative, unless it be decided advisable to attempt eradication, which may offer some chance of success in intrinsic carcinoma still confined to the larynx. Laryngectomy may be unilateral in some instances, and must be bilateral in others. Unilateral laryngectomy is the more hopeful. Eradication proffers no hope in cases of extrinsic carcinoma in which the growth has passed the boundaries of the larynx. After recovery from the laryngectomy an artificial appliance may be adjusted to the parts for the purpose of supplying a mechanical method of producing sound in the larynx for speaking purposes. Should no radical procedures be instituted, treatment is relegated to general principles, with prophylactic performance of tracheotomy in the presence of dangerous occlusion of the larynx. The voice should be used but little. All sources of laryngitis should be avoided. Ergot or hamamelis may be given to restrain hemorrhage, and morphine to relieve pain and secure sleep. Sprays can be used to keep the parts free from morbid products. Erythroxyline may be applied to produce local anæsthesia as required. Semi-detached portions of growth may be removed from time to time. Nourishment may be given by the bowel when necessary, and so on as in other diseases of the larynx in which the functions of respiration and deglutition are seriously impaired. Medicinally, arsenic may be given in the early stages, as that drug is conceded to possess some slight retarding influence on the growth of carcinoma.
Lupus of the Larynx.
Lupus is rare in the larynx. It usually occupies the structures above the vocal bands. It is most frequent in females, and usually associated with cutaneous lupus.
ETIOLOGY.—Scrofulosis and syphilis seem to be the predisposing causes. Climate may have some influence. The reason of the special proclivity of the female is undetermined. Of 9 reported cases, records of which are before the writer, 8 were in females.
PATHOLOGY AND MORBID ANATOMY.—Laryngeal lupus is usually an extension of the disease from the upper lip or the nose, extending along the nasal passages, pharynx, and palate. Destructive ulceration takes place, with irregular cicatrization and the formation of hard nodules of hyperplastic tissue of irregular conformation, varying from the size of hempseeds to that of small peas, similar to the cutaneous buccal and pharyngeal nodules.
SYMPTOMS.—These include dysphonia, dyspnoea, dysphagia, and cough. Pain is exceptional.
DIAGNOSIS.—Laryngoscopic inspection reveals the characteristic nodulation, the nature of which is inferred from the coexistence of external lupus. The disease may be confounded with lepra, syphilis, tuberculosis, or carcinoma. Discrimination from syphilis is the most difficult, and is predicated chiefly on its slow progress and on the absence of constitutional manifestations.
PROGNOSIS.—This is unfavorable. The reported cures seem to have occurred only under the influence of antisyphilitic treatment.
TREATMENT.—The prolonged use of cod-liver oil and of potassium iodide seems to be more beneficial than any other systemic treatment. Destruction of the nodules and ulcerated tissues is indicated when the diseased structures are sufficiently circumscribed and accessible. This may be done with the sharp spoon or with the electric cautery. Silver nitrate and iodine have been lauded as topical remedies.
Lepra of the Larynx.
Lepra is rare in the larynx.
ETIOLOGY.—Its cause seems to be climatic. In Europe it is most frequent in Norway and Sweden, and in America in Cuba and the West Indies.
PATHOLOGY AND MORBID ANATOMY.—It is always associated with cutaneous lepra, and usually with lepra of the nasal passages and the pharynx. According to Schroetter's observations, laryngeal lepra occurs as small connective-tissue nodules on the epiglottis or in the interior of the larynx, or as uniform thickenings, general or circumscribed. These may lead to stricture. Extensive ulceration may ensue.
SYMPTOMS.—Dysphonia, aphonia, dyspnoea, cough, and local anæsthesia are the main symptoms. Pain is infrequent.
DIAGNOSIS.—This depends upon the external manifestations of lepra and the laryngoscopic detection of the characteristic thickenings and nodulations.
PROGNOSIS.—This is unfavorable.
TREATMENT.—This must be conducted on general principles. Elsberg commended iodoform topically and gurgun oil internally.
