TRANSNASAL ENDOSCOPIC APPROACH FOR SINONASAL INVERTED PAPILLOMA

Inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. This article presents the results of a prospective study of24 patients with inverted papilloma resected by the endoscopic approach. 21 patients had unilateral disease and three patients had bilateral involvement. None of the patients had orbital or cranial extension. No association with malignancy was seen. Following endoscopic surgery, four patients had recurrences that required surgery. No complication occured in any of the patients. The results of endoscopic surgery for inverted papilloma is much better than nonendoscopic transnasal approaches and compares favorably with radical extranasal approaches. Endoscopic surgery is an effective surgical option for inverted papilloma removal.
