Abstract:
OBJECTIVES: Inverted papilloma is characterized by a high rate of recurrence, local aggressiveness and association with malignancy. We reviewed the 16-year experience of our institution in clinical presentation, history and the recurrence rate according to the tumor stage and surgical modalities. MATERIALS AND METHOD: A retrospective study was conducted on 102 patients diagnosed as inverted papilloma between January, 1986 through August, 2002. Demographic data, clinical presentations, and association with malignancy were analyzed. All patients with inverted papilloma were staged according to the Krouse's staging system. Sixty eight patients followed up at least 6 months were divided into endoscopic and conventional surgery groups. We compared the recurrence rate between the two groups according to the tumor stage. RESULT AND CONCLUSION: Patients were aged 19 to 81 years, and 73.5% were male. The most frequent presenting complaint was nasal obstruction. The most common site of involvement was the lateral nasal wall in the region of the middle meatus. The overall malignancy rate was 8.8% (9 cases), with synchronous tumors accounting for 7 cases and metachronous tumors accounting for 2 cases. When patients were first diagnosed, the most common stage was T2 (52.7%). The recurrence rates of T1, T2 and T3 were 10%, 11.1% and 4.8%, respectively, with no significant difference. Also the recurrence rates in endoscopic and conventional surgery group according to the stage had no significant difference.
