Abstract

BACKGROUND AND OBJECTIVES
Recently, rhinologists have increasingly applied their expertise in endoscopic sinus surgery to the resection of sinonasal neoplasms. However, there have not been many reports about long-term follow-up outcomes about endoscopic resection of sinonasal benign tumor. The purpose of this study is to evaluate long-term results of endoscopic management in sinonasal benign tumors. SUBJECTS AND METHOD: We reviewed retrospectively the medical records and radiologic findings of 35 patients with sinonasal benign tumors, who had been treated with transnasal endoscopic resection between January 1995 and December 1999 at Yeungnam University Medical Center and followed over a 5-year. RESULTS: Inverted papilloma (22 cases, 62.8%) was the most common of benign tumor, followed by hemangioma (4 cases), fibrous dysplasia (2 cases), angiofibroma (2 cases), etc. Among of the 22 cases of inverted papilloma, there were 4 cases of T1, 12 of T2 and 6 of T3 according to the Krause staging system. The most common chief complaint was unilaterally nasal obstruction. The mean follow-up period was 6.5 years (5-8 years). There was no major complications, with only one case (4.5%) of recurrent inverted papilloma observed during the following-up period. CONCLUSIONS: The transnasal endoscopic surgical procedure is less aggressive than other methods and except for massively extended cases of sinonasal benign tumors, it is a successful, therapeutic surgical method.
