Abstract

Sinonasal schwannomas constitute 4% of head and neck nerve sheath tumours; however, schwannomas involving the nasal septum are quite rare. We present a 57-year-old male patient with nasal septal schwannoma who was managed successfully by endoscopic excision. 32 cases of septal schwannoma have been reported so far in the literature. This report discusses certain peculiar features exhibited by schwannomas of the nasal septum. Septal schwannoma does not show any age, sex or side predilection. However, they tend to involve posterior part of the septum and presumed to arise from the nasopalatine branch of the trigeminal nerve. Imaging findings of the sinonasal schwannoma are non-specific, but the histopathological characteristics are diagnostic, with seldom need for immunohistochemistry. Endoscopic excision is the safe and effective treatment option for the septal schwannoma of any size and location. Recurrence has not been reported in the literature following endoscopic excision.
