Laryngeal Schwannoma Excision by Lateral Pharyngotomy

Abstract

Neurogenic tumors of the larynx are extremely rare. Here, we are reporting a case of laryngeal schwannoma presenting as supraglottic submucosal lesion with hoarseness and stridor, which was excised by lateral pharyngotomy approach. This presentation is to further discuss the histology of neurogenic tumors, modes of presentation, differential diagnosis and treatment modalities.
