Abstract

Inverted papilloma is a rare sinonasal tumor that mainly occurs in adults during the 5th decade. Three characteristics make this tumor very different from other sinonasal tumors: a relativelystrong potential for local destruction, high rate of recurrence, and a risk of carcinomatous evolution. Etiology remains little understood, but an association with human papilloma virus hasbeen reported in up to 40% of cases, raising the suspicions of implication in the pathogenesisof inverted papilloma. Treatment of choice is surgery, by endonasal endoscopic or external approach,depending on extension and tumoral characteristics. We experienced a case of 42-yearoldmale with inverted papilloma which originated from the ethmoid roof and spread into thefrontal sinus. He was treated successfully by unilateral osteoplastic flap surgery without obliteration,and we report on the treatment of this case, along with a review of literature.
