RESUMEN
BACKGROUND: Inverted papilloma is a benign neoplastic lesion which shows high recurrence rate and possibility of association with malignancy. Medial maxillectomy has been preferred as a treatment of choice, for conservative treatments resulted in higher recurrence rate. However, introduction of nasal endoscope made more precise evaluation of intranasal lesion under brighter illumination. OBJECTIVES: Aim of this study was to compare the recurence rate between medial maxillectomy and conservative surgery using nasal endoscope. MATERIAL AND METHODS: Thirty one patients who underwent operation between 1980 and 1995 were retrospectively studied. RESULTS: Fifteen patients were treated via external approach and sixteen patients endoscopically. Inverted papilloma was recurred in two cases of endoscopic surgery group and one case of external surgery group. CONCLUSION: Endoscopic conservative surgery can be an alternative surgical modality in the selected cases.
