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 relatively strong 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 has been reported in up to 40% of cases, raising the suspicions of implication in the pathogenesis of 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-year-old male with inverted papilloma which originated from the ethmoid roof and spread into the frontal 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.
