ENDOLARYNGEAL NEUROFIBROMA

Abstract

Neurofibromatosis is a benign neurogenic tumor, originatig from Schwann cells of the nerve sheath. This tumor forms a round, white mass on the course of the involved nerve. It occurs sporadically or in association with von Recklinghausen's disease. Laryngeal involvement is a rare occasion that affects women more than men (F/M ratio 3:2). The most common symptoms are hoarseness, dyspnea and dysphagia. The most common sites of origin are arytenoids and aryepiglottic folds. Because of benign nature of this tumor, conservative surgery is recommended as the management of choice. Only few cases of laryngeal involvement have been reported in literatures and this article presents two cases of laryngeal neurofibroma with brief review of literatures. Both cases had submucosal, non-ulcerated, endolaryngeal mass with signs and symptoms of airway compromise. In both cases surgical approach was endolaryngeal conservative surgery with CO₂ laser.
