目的 :探讨鼻内镜下微波治疗鼻咽癌 (NPC)放疗后后鼻孔闭锁的远期疗效。方法 :对2 1例NPC放疗后后鼻孔闭锁患者采用鼻内镜与微波相结合的方法 ,经鼻腔切除膜性闭锁 ,术后分期进行随访。结果 :随访 3年以上 ,2 1例患者鼻腔均达到正常通气 ,无再狭窄和闭锁 ,治愈率达10 0 %。结论 :本方法具有操作简便、术野清晰、组织损伤轻、患者痛苦少、远期疗效可靠等优点 ,是治疗NPC放疗后后鼻孔闭锁较为理想的方法。 Objective: To investigate the long-term efficacy of endoscopic nasopharyngeal microwave irradiation in the treatment of nasopharyngeal atresia after nasopharyngeal carcinoma (NPC) radiotherapy. Methods: Twenty-one NPC patients with post-nostril atresia were treated with nasal endoscopy combined with microwave. Membranous atresia was performed through nasal cavity and followed up by staging. Results: All cases were followed up for more than three years. Twenty - one patients had normal nasal passages, no restenosis and atresia, and the cure rate was 100%. Conclusion: The method has the advantages of simple and convenient operation, clear surgical field, less tissue damage, less pain and long-term curative effect. It is an ideal method for the treatment of nostril atresia after NPC radiotherapy.
