Laryngeal schwannoma: excision via a laryngofissure approach

Abstract

Schwannomas are peripheral nerve neurogenic tumours and although not common, laryngeal schwannomas can provide a unique challenge in diagnostic and treatment management. There are limited reports in the literature on approaches to management. A 73-year-old lady presented to the otolaryngology department after a MRI scan demonstrated an incidental right supraglottic mass. Further investigations included CT scanning and microlaryngoscopy, which only confirmed the presence of the mass with no histology diagnosis. Excision was undertaken by a laryngofissure approach and tracheostomy. Histology confirmed a benign ancient schwannoma.
