Abstract
Since 1990, twenty-three cases with papilloma in the nose and paranasal sinuses have been surgically treated at Kobe University Hospital. Five of them had received prior surgery. The tumors arose from the lateral nasal wall in 22 cases, and from the nasal septum in one. Tumor extension involved the maxillary sinuses in 13 cases and the ethmoid sinuses in 12. The tumors were resected en bloc in all cases. Eleven patients whose ethmoid sinuses were involved were treated with external resection through lateral rhinotomy approach, while tumors infiltrating the maxillary sinuses were resected through sublabial approach in nine cases. Endonasal resection was performed in three cases of which tumors were localized in the nasal cavity. There have been no recurrences. The overall incidence of carcinoma in our series was 17.4%, with synchronous lesions present in three patients, and one patient later developed a recurrent inverted papilloma associated with a carcinoma. Our experience shows that it is important to select the appropriate surgical approach with which the tumor can be resected en bloc.
