Abstract

Background:Schwannomas are benign tumors of ectodermal origin derived from Schwann cells of the nerve sheath. Approximately less than 4% of these tumors are found in the paranasal sinuses and there has been little information reported concerning the presentation and surgical management of sinonasal schwannomas. The purpose of this study was to analyze the clinical data, management, and long-term outcomes of sinonasal schwannomas.
Methods:Retrospective chart review of patients with sinonasal schwannomas treated from January 2001 to March 2012 was performed. Clinical data and follow-up information were obtained from a review of the patients’ charts and the operative, anesthesia, and pathology reports.
Results: There were 4 females and 4 males included in this study. The mean age was 37.5 years (range, 22-51 years). The mean tumor size was 3.1 cm (range 1.0-6.0 cm). The origin of the tumors included: nasal septum (n = 2), nasal vestibule (n = 2), pterygopalatine fossa (n = 2), ethmoid sinus (n = 1), and inferior turbinate (n = 1). Seven patients had endoscopic resections and one patient with a schwannoma in the nasal vestibule underwent a sublabial approach. The mean follow-up was 59 months. There were no tumor recurrences during the study period.
Conclusions:Schwannomas in sinonasal cavity can be treated effectively with the endoscopic approach with minimal morbidity and long-term disease control.
