Re methods for curing aphonia, Muck has a method called the “ball” method. A ball is put into the larynx to cause a temporary suffocation, which produces a reflex that starts the adductors. He would apply the method as soon as the man was well over the shock that produced aphonia. Muck states that he has applied the ball method, not only to cases of aphonia, but to cases of mutism and deafness, with success.

Tilly mentions a case in which the patient refused to open his mouth, so the device was adopted of passing an electrode through the left nostril so that it finally reached the larynx. A spasm was produced, which was carried to the point of considerable cyanosis, but the aphonia was relieved and for the first time in three months the man spoke. Incidentally he began to hear also.

Re treatment of aphonia, Schultz has used the electric current externally over the larynx, all the while carrying on a laryngoscopy. Schultz remarks upon the fatigue that may come during the first few sittings. Roussy and Lhermitte remark that, although aphonia sometimes exists from the outset of shock, it is often a phase in recovery from mutism.

Liébault notes that, not only cases of true nervous aphonia but cases of laryngitis, apparently of infectious origin, and cases of true voice strain, may also turn up for treatment. Some men have been improperly discharged from the army for aphonia actually due to voice strain.

Hysterical aphonia in a mechanician (war time contributory?). Cure by suggestive manipulation of larynx.

Case 519. (Vlasto, January, 1917.)

A mechanician was refitting an engine valve, when steam was suddenly put on and the drains were opened out. Some of the steam entered the throat of the mechanician, who rushed up, gasping, unable to speak. Oedema of the larynx was thought of; but there was no complaint except the inability to speak.

A month later he was discharged to the hospital ship at Plassy, where he got faradic treatment, the effect of which was to cause him pain without recovery of voice. The man could whisper well enough and cough fairly loudly. The vocal cords of the larynx appeared normal on laryngoscopic examination, but adduction of the cords was not be properly effected. He was now given rest and constant assurances that he would get well.

Ten days later, another laryngoscopic examination was made, with mild mechanical stimulation of the air passage. The patient remarked that he had never been so near being able to speak since his dumbness came on. The patient was now informed that his muscle of talking was going to be replaced and that the success of the operation depended upon his help, so that he was to shout out as soon as he became conscious of the physician’s working inside his throat. The patient was given ether lightly, into the second stage. When consciousness was about to return, the laryngeal mirror was placed lightly on the larynx. The patient was commanded and encouraged to count out loud and shout. Speech returned permanently.
