ABSTRACT
BACKGROUND AND OBJECTIVES: Inverted papilloma is charicterized by a high rate of recurrence, local aggresiveness and occasional association with malignancy. Most authors have recommended medial maxillectomy as the initial surgical approach. Howerer, conservative surgery has been reported to be effective in selective cases. MATERIAL AND METHODS: Six patients were treated by intranasal endoscopic exicision from 1993 to through 1995. Among the six patients, 3 patients with maxillary sinus involvement were treated with Denker operation or Caldwell-Luc operation combined with endoscopic endonasal surgery. RESULT: Two patients were found to have malignancy ssociated with inverted papilloma. There is no evidence of recurrence at the present time. CONCLUSION: This study shows the possibility of endoscopic surgery as an initial approach for inverted papilloma.
