BACKGROUND: This study was designed to investigate the role of endoscopic surgery for acquired @entity16453 after radiotherapy for @entity189 . METHODS: Twenty-two @entity1 with bilateral or unilateral acquired @entity16453 received transnasal endoscopic surgery with the aid of a powered microdebrider to open @entity1146 choana and received endoscopic sinus surgery simultaneously if they had @entity1244 . Merocel @entity1415 packing was used to pack the nasal airway for 3 days postoperatively. All of the @entity1 underwent endoscopy regularly for follow-up. RESULTS: Sixteen @entity1 with acquired bilateral @entity16453 and 6 with unilateral @entity16453 were included in this study. The median age was 46 years old (range, 33-65 years). Twenty-one @entity1 had @entity1244 . Sixteen @entity1 with bilateral @entity16453 and 4 @entity1 with unilateral @entity1146 had bilateral @entity1244 . One @entity1 with unilateral @entity1146 had ipsilateral @entity1244 . The mean follow-up period was 35 months (range, 12-72 months) after surgery. Twenty @entity1 were symptom-free after a single operation; nasal obstruction, @entity5254 , and @entity2133 improved significantly for these @entity1 . Two @entity1 had unilateral restenosis that required revision surgery, and both were subsequently free from further restenosis. No complications occurred. CONCLUSION: Acquired posterior @entity16453 after radiotherapy can be successfully treated with transnasal endoscopic resection assisted by a powered instrument without stenting.
