Albert H. Buck of New York, in a highly instructive paper read before the International Medical Congress in 1876, writes as follows of paracentesis of the membrana tympani in scarlatinous otitis: "In this one slight operation, which in itself is neither dangerous nor very painful, lies the power to prevent the whole train of disagreeable and dangerous symptoms." Buck relates an instructive example: The age of the patient was three years, and the earache had been complained of only about twenty-four hours. "Toward morning," says he, "I was sent for, as the pain had become constant.... An examination with the speculum and reflected light showed an oedematous and bulging membrana tympani (posterior half), the neighboring parts being very red, though as yet but little swollen. In the most prominent portion of the membrane I made an incision scarcely three millimetres (one-tenth inch) in length, and involving simply the different layers of the membrana tympani. This was almost immediately followed by a watery discharge (without the aid of inflation), which ran down over the child's cheek. At the end of three or four minutes the child had ceased crying, and in less than a quarter of an hour she was fast asleep. At first, the discharge was very abundant and mainly watery in character, but it steadily diminished in quantity and became thicker, till finally, on the fourth day, it ceased altogether. On the tenth day the most careful examination of the ear could not detect any trace of either the inflammation or the artificial opening." The ear had probably been saved from ulceration of the drum membrane, long-continued suppurative otitis, and perhaps from permanent impairment of hearing.

When an opening has been made in the membrana tympani either by incision or ulceration, it is advisable in some instances to inflate the tympanum by Politzer's method, which has been alluded to above. The nozzle of an india-rubber bag, with a flexible tube attached, is introduced into the nostril on the affected side, and both nostrils are compressed against it. The patient fills his mouth with water, which he swallows at a given signal, as after the words one, two, three, spoken by the operator. During the act of swallowing, which opens the Eustachian tube, the rubber bag is forcibly compressed, which forces the air along the tube into the middle ear and facilitates the escape of the pent-up secretions in the tympanic cavity.

If the otitis have continued unchecked by treatment until the secretions within it, after days and nights of suffering, have escaped by ulceration through the drumhead, the opportunity for prompt and certain cure is passed. Still, the patient under these circumstances may quickly recover, or there may be the other alternative described above, in which the ear is badly damaged and chronic inflammation established in the walls of the tympanum, giving rise to an offensive otorrhoea. In this state of the ear internal remedies are indicated, such as surgeons employ in suppurative inflammations of bone occurring in other parts of the system. Cod-liver oil and iodide of iron are required, especially by patients of strumous diathesis, the object being to promote a more healthy state of system, so as to prevent extension of the inflammation and facilitate the healing process. Carbolized solutions, as the following, syringed warm into the ear in which otorrhoea is occurring, are useful in promoting cleanliness and increasing the comfort of the patient:

Rx.Acidi Carbolicidrachm ss;
Glycerinæfl. oz. ii;
Aquæfl. oz. iv. M.

But recently a much more effectual curative agent for local treatment has been discovered in boracic acid, by the use of which the discharge more quickly diminishes and the condition of the ear more certainly and rapidly improves than by the use of the carbolized mixtures. When the inflammation is recent and the ear sensitive and painful, the following prescription should be used:

Rx.Acidi Boracicidrachm iiss;
Morphiæ Sulphat.gr. i;
Glycerinæ
Aquæ aa.fl. oz. i. M.

S. Drop one to three drops into the ear three times daily.

If the acute stage of the otitis have passed, with fever and pain, and no tenderness be present on pressure, the following prescription, which causes too much pain in the acute stage, will be found useful to check the inflammation and otorrhoea and restore a healthy state to the granulating surface:

Rx.Acidi Boracicidrachm iiss;
Alcohol.
Aquæ aa.fl. oz. i.

S. Drop one to three drops into the ear three times daily.
