A Case of Schwannoma Originated from the Posterior Nasal Septum / 대한이비인후과학회지

ABSTRACT

Schwannomas are slow-growing, benign neurogenic tumors arising from the sheath of myelinated nerve fibers. They usually occur in the head and neck region. Only 4% of schwannomas found in the head and neck region originate in the sinonasal tract. Schwannoma of the nasal septum is rarer, and only few cases have been previously reported in the literature. We experienced a rare case of the schwannoma of the posterior nasal septum in a 71-year-old woman. She was treated successfully by transnasal endoscopic surgery. No recurrence was detected within 18 months follow-up period.
