Endoscopic Excision of Cribriform Plate Schwannoma: A Case Report

Abstract

Although 25-45% of all schwannomas occur in the head and neck, nasal and paranasal sinus presentations are rare in the literature. Here we report the case of a 67-year-old woman with a nasal schwannoma. Computerized tomography (CT) showed the mass completely occluding the nasal passage with evidence of a secondary maxillary sinusitis. A preoperative biopsy suggested the presence of a benign schwannoma. She underwent a complete endoscopic sinus surgery to remove the mass arising from the cribriform plate. Six years after surgery, the patient remains asymptomatic and without endoscopic evidence of recurrence. This case demonstrates that it is possible to achieve a complete excision of a nasal schwannoma endoscopically, which is similar to results observed for other benign nasal tumors.
