Endoscopic Approach to Sinonasal Inverted Papilloma Using the Swinging Technique of Nasolacrimal Duct and Inferior Turbinate

Abstract

Advanced endoscopy has become preferred modality in treating sinonasal inverted papilloma (IP) with Krouse staging T3 case. We applied maxillary swing approach to the nasolacrimal duct and inferior turbinate for IP because it provides a wide surgical field for the maxillary sinus without damaging for the nasolacrimal duct or inferior turbinate mucosal function. This is easily switched perioperatively to endoscopic medial maxillectomy (EMM) in cases of nasolacrimal duct or inferior turbinate invasion.
Since 2006, we have treated 23 subjects in 27 cases of IP surgery, including 5 using the Swing Method and 3 EMM classified as Krouse staging T3. Most T3 cases can be managed with one of these modalities.
