Management of inverted papilloma of the nose and paranasal sinuses

Since July 1989, twenty-four patients with inverted papilloma of the nose and paranasal sinuses have been treated at Mackay Memorial Hospital. Patients were aged from 11 to 72 years, and 70.8% were male. Unilateral nasal obstruction (70.8%) and epistaxis (41.7%) were the most common symptoms. Most tumors originated on the lateral nasal wall, with 95.8% involving the adjacent sinuses. Five cases were treated by extranasal approach and nineteen were treated by other intranasal procedures, including nine cases of endoscopic sinus surgery. There were two recurrences (10.5%) in intranasal group and no recurrence in extranasal group. Total recurrence rate on patients was 8.3%. There were no cases associated with squamous cell carcinoma in this study.
