The main treatment modality of sinonasal benign tumor is surgical resection, and the endoscopic intranasal approach has been commonly performed since the 1990s. The objective of this study was to evaluate the recurrence rates of different sinonasal benign tumors and to analyze the diverse approaches used in their surgical treatment. SUBJECTS AND METHOD: In 270 patients who were histopathologically diagnosed with sinonasal benign tumor during a period of 20 years, histopathologic type, treatment approach, interval between first treatment and recurrence, and recurrence rate according to treatment approach were analyzed.
Recurrence rate was higher with the intranasal approach than with the extranasal approach in inverted papilloma and angiofibroma, but the differences were not statistically significant. The proportion of the intranasal approach during the latter 10 years was higher than that during the former 10 years. There was no significant differences between the recurrence rate during the former 10 years and that during the latter 10 years for both intranasal and extranasal approaches.
Based on tumor location and stage and skill of the surgeon, the intranasal approach can replace the extranasal approach with no major changes in treatment outcome.
