title: Transnasal endoscopic medial maxillectomy in inverted papilloma.
abstract: This study comprised 17 cases of inverted papilloma, which were divided into two groups. The first group included 8 cases that lacked maxillary sinus involvement. They were subjected to intranasal endoscopic resection with safety margin. The second group included 9 cases involving the maxillary sinus with or without nasal extension. They were subjected to transnasal endoscopic medial maxillectomy. Follow-up for an average of 43 months in group 1 and 28 months in group 2 (excluding the 5 cases with less than 2 years of follow-up) showed no recurrence. The author realized that inverted papilloma can be divided into two groups from the anatomic and behavioral points of view and accordingly should be managed differently. For those lesions without involvement of the maxillary sinus, intranasal endoscopic resection is effective; for those lesions with maxillary sinus involvement, transnasal medial maxillectomy, which could be performed safely under endoscopic control, is recommended.
