Our results support the endoscopic approach as the treatment of choice when feasible in patients with inverted papilloma, combined in selected cases with external approaches. The Krouse and Cannady systems provided a good distribution of patients according to local control.

The aim of this study was to describe the endoscopic medial maxillectomy technique with preservation of the inferior turbinate in patients affected by maxillary sinonasal inverted papilloma. We retrospectively reviewed the clinical charts and surgical technique in six patients with paranasal sinus inverted papilloma. There were five males and one female, whose mean age at diagnosis was 60 years ranging between 57 and 65 years. No recurrences were diagnosed, and no nasal crusting was evidenced postoperatively. Nasal breathing was satisfying in all cases. Postoperative epistaxis was not observed, and none of the patients refereed to have epiphora after the surgery. This technique has been successfully performed, showing no recurrence to the present and allowing the preservation of a functional inferior turbinate.

The unilateral septal flap pedicle by anterior ethmoidal artery may be used for small and medium perforations with a pedicle smaller than 1 cm posterior to the axilla.
