Objectives To introduce a new surgical technique for endoscopic removal of the antral portion of antrochoanal polyp (ACP) by powered instrumentation and to determine its efficacy by measures of relevant patient outcome. Study Design Prospective study in 28 patients undergoing endoscopic sinus surgery for ACP by our surgical technique. Methods Improvements of clinical symptoms and endoscopic and computed tomographic findings were evaluated postoperatively with a follow‐up period ranging from 12 to 52 months. All symptom scores on a 100‐mm visual analogue scale before operation were compared with those at the last visit after operation. Postoperative endoscopic and computed tomographic findings were graded using a three‐point scale ranging from 0 to 2. In surgical technique, the antral portion of ACP was identified through the enlarged ostium under intranasal endoscopy and removed by a blade of powered instrumentation that was inserted through the canine fossa. Results Symptom scores were all significantly reduced postoperatively. All but one patient showed improvement in clinical symptoms and endoscopic and computed tomographic findings during the follow‐up period. There were no major complications specific to this technique. Conclusion Our technique provides an attractive alternative to other methods for removing the antral portion of an ACP and is associated with excellent outcomes and minimal morbidities.
