Management of maxillary sinus inverted papilloma via endoscopic partial medial maxillectomy with an inferior turbinate reversing approach.

The aim of this study is to evaluate the efficacy of endoscopic treatment for maxillary inverted papilloma (IP) through partial medial maxillectomy with an inferior turbinate reversing approach. A retrospective analysis of patients treated in our institution for maxillary sinus IP between July 2011 and August 2015 was performed. Demographics, operative technique, characteristics of tumors, complications, postoperative follow-up, and recurrence were evaluated. Twenty-two patients were enrolled in the study. All tumor attachments were identified intraoperatively. Adequate visualization was obtained following our approach. All inferior turbinate and nasolacrimal ducts were preserved. The median follow-up time was 41 months. One recurrence occurred at the follow-up time of 27 months. Postoperative hemorrhage and numbness at the ipsilateral frontal teeth were reported in two and one patients, respectively. Endoscopic surgery through partial medial maxillectomy using an inferior turbinate reversing approach provides full access to the maxillary sinus and preserves the inferior turbinate and nasolacrimal duct.
