Hypopharyngeal neurinoma is a rare disease. We report two cases of hypopharyngeal neurinoma. One case was a 49 year-old male who had complained of snoring and a foreign body sensation of the pharynx for a half year and the other was a 54 year-old female who had had a feeling of nocturnal dyspnea for a month. Each tumor was located in the right pyriform sinus and the right vocal cord was fixed in both cases. The tumors were removed by lateral pharyngotomy in one case and by laryngomicrosurgery in the other. We were unable to trace the original nerve in both cases. The mobility of the right vocal cord remained impaired after surgery and atrophy of the vocal cord progressed gradually in both cases.
Key words :
hypopharynx, neurinoma
