Schwannoma Originating from the Superior Turbinate

Schwannoma in the nasal cavity is rare. Only 4% of head and neck schwannomas occur in the sinonasal cavity. Sinonasal schwannomas are postulated to arise from the ophthalmic and maxillary branches of the trigeminal nerve, or from autonomic nerves to the septal vessels and mucosa. Various origins of nasal schwannomas have been reported in the literature, including the inferior turbinate, middle turbinate, nasal septum, and nasal vestibule. We report the findings for a 40-year-old man who presented with nasal obstruction due to a schwannoma originating in the superior turbinate. (J Clinical Otolaryngol 2016;27:357-361)
