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.

Intraorbital abscess is one of the serious complications of the paranasal sinusitis and an inadequate treatment for this condition may result in irreversible damages of the optic nerve and retina. Conventionally, surgical treatment of intraorbital abscess has been performed by external ethmoidectomy approach. More recenty, the endoscopic drainage technique has been reported. The authors experienced a case of intraorbital abscess in a 16 year-old male patient for whom we applied the endoscopic drainage technique under the general anesthesia. After the partial removal of the lamina papyracea, we incised the periorbita and then induced drainage of intraorbital abscess by applying external pressure to the eye ball. The surgery was satisfactory and there was no evidence of complications.
