Abstract
A considerable number of patients have visited our clinic with the chief complaint of abnormal sensation in their pharynx, larynx and esophageal entrance. Recently such cases seem to be increasing in number.
As to the etiology, while many hypotheses have been postulated, no definite theory has yet been brought out. 77 such cases have been studied from the standpointed of age, sex, degree, variety and location of abnormal sensation. Simulataneouly, endoscopic and radiologic examinations have been carried out. Results of these clinical observations indicate that the function of superior cervical ganglion and its sympathetic sensory division (nerve), directly or indirectly seem to play an important role.
