Abstract
Schwannoma is a neurogenic tumor arising in peripheral nerve sheath Schwann cells. Most head and neck schwannomas occur as acoustic neurinomas, with sinonasal involvement accounting for 3%. Complete resection is vital to preventing local recurrence. Extended resection may be difficult however due to paranasal sinus location. We report a case of sinonasal schwannoma resected in endoscopic sinus surgery and discuss the usefulness of and about indications for intranasal schwannoma treatment.
