Abstract
We have been able to find recorded in the literature only fourteen cases of paralysis of the superior laryngeal nerve. Mygind1 reviewed thirteen cases in 1909, and Topia2 reported a case in the following year. Paralysis of this type, as other types of paralysis of the larynx, is important because of the symptoms it produces and the aid it affords in the diagnosis of lesions of the central or peripheral nerves. The case reported here of unilateral complete superior laryngeal paralysis is particularly interesting on account of its association with arteriosclerosis of the central nervous system. The superior laryngeal branch of the vagus nerve supplies sensation to the mucous membrane of the larynx, and is the motor nerve to the cricothyroid muscle, the external tensor of the larynx, which assists in rendering the vocal cord tense on phonation by fixation of the thyroid gland on the cricoid cartilage.
