Abstract

Abstract

Inverted papilloma is an uncommon sinonasal tumor which has a high incidence of local invasion and local recurrence in addition to the risk of coincidental carcinoma. The etiology is still unknown but may be related to human papilloma virus, usually type 6 and 11 especially in recurrent cases. Many tumor staging systems have been purposed.  Krouse and Cannady systems correlated better with the prognosis. CT scan not only gives detail of tumor extension but can also identify the origin by signs of focal bony sclerosis. The treatment modality is surgical removal by conventional or endoscopic surgery which has equal local control rate. Complete removal of the tumor origin and its underlying bone is the key to success. Lifelong follow up is necessary because delayed recurrence and malignancy change may still occur after several years of surgery.
