A Clinical Study on the Surgical Treatment of Inverted Papilloma / 대한이비인후과학회지

ABSTRACT

BACKGROUND: Inverted papilloma is an uncommon benign tumor which is characterized by local aggressiveness, high recurrence rate, associated malignancy and tendency to multicentricity. Most authors advocate radical surgical removal of these tumors; however, conservative endoscopic surgery has been reported to be effective in selected cases. OBJECTIVES: To compare with operative methods of the inverted papilloma. MATERIAL AND METHODS: This study comprised 14 cases of inverted papilloma, which were divided into 3 groups. The first was lateral rhinotomy and traditional medial maxillectomy treated group with 7 cases. The second group was treated with conservative endoscopic intranasal resection of 4 cases and the third group was treated by endoscopic medial maxillectomy of 3 cases. RESULTS: The follow-up periods in average were 23 months, 19 months and 11 months in first, second and third groups respectively. All cases showed no recurrence. CONCLUSION: Although follow-up periods are insufficient, the endoscopic approaches are meaningful methods to treat inverted papilloma.
