PARALYSIS OF THE LARYNX. 4OI Bilateral paralysis of the lateral cricoarytenoids is a very rare con-dition. The laryngeal image is almost identical with that of bilateralparalysis of the recurrent laryngeal nerve. It may result from lead-poisoning, diphtheria, or from one of the exanthemata. Unilateral paralysis is also very infrequent and is due to causessimilar to those just mentioned. It is characterized by impairedrather than complete loss of voice, the unaffected cord attempting tocompensate for the paralysis of the opposite cord by crossing the. Fig. 138.

The prognosis, in all these forms of paralysis, is, as a rule, favor-able provided we can place the patient under proper conditions. The first indication in all is to secure rest for the larynx; in thesecond place, to remove the cause of the affection if it can be dis-covered. Electricity, by means of faradism or galvanism, may beused every day for ten or fifteen minutes, one electrode being placedwithin the larynx, the other externally. The general health shouldreceive attention and the use of tonics, exercise, full diet and strych-nia to its physiological effect, will assist recovery. The most common form of paralysis of the vocal bands due to nervelesion is recurrent laryngeal paralysis, which may be traced, in a largeproportion of cases, to pressure upon the recurrent laryngeal nerve
