All patients were treated by intronasal endscopic surgery and were followed up for 24 months. RESULTS The inverted papilloma was removed completely and no serious complications occurred. One case recurred at 10 month after surgery and pathologically proved to be cancerated. Another 2 case recurred at 6 and 7 month after surgery respectively. Recurred tumors were removed again, no recurrences occurred in the following up period. The recurrence rate was 10 % and canceration rate was 3.3 %. CONCLUSION Endoscopic surgery is an effective method in management of the inverting papilloma in nasal cavity and paranasal sinuses in stage Ⅰ-Ⅲ.
