Turbinate‐Conserving Medial Maxillectomy for Sinonasal Inverted Papilloma

Abstract

Objective: Present the authors' experience and outcomes in the maxillary inverted papilloma using turbinate-conserving medial maxillectomy, so-called swinging-turbinate procedure. Method: Case series with retrospective investigation. Results: Endoscopic medial maxillectomy (EMM) is one of the best approaches for the maxillary tumor arising from the lateral and/or frontal wall of the maxillary sinus. However, the function of turbinate mucosal membrane is sacrificed. We present turbinate-conserving medial maxillectomy, providing wide surgical fields that compare favorably with EMM. The most distinctive feature of the swinging-turbinate procedure is conserving the inferior turbinate membrane and the nasolacrimal duct. Five of 45 patients who underwent swinging-turbinate procedure qualified for the analysis. The outcome of the surgery was satisfactory except for 1 case of recurrence. Conclusion: Most of the T3 cases and some of the T4 cases in Krouse's classification system can be treated as ESS. Swinging- turbinate procedure provides good results for IP.
