目的 :探讨悬雍垂腭咽成形术 ( UPPP)并发鼻咽狭窄的原因、预防与治疗方法。方法 :报告2例 UPPP后并发重度鼻咽狭窄患者的临床资料。结果 :1例局部手术和激光矫治狭窄失败 ,1例转粘膜瓣和鼻咽支撑物治疗成功 ,随诊 2 0个月无复发。结论 :UPPP后鼻咽狭窄发生与腭咽弓切除较多、术中长时间止血损伤鼻咽入口处粘膜及激光使用不当有关。鼻咽狭窄治疗困难 ,预防是最好的治疗。
Objective: To investigate the causes, prevention and treatment of nasopharyngeal stenosis complicated by uvulopalatopharyngoplasty (UPPP). Methods: The clinical data of 2 patients with severe nasopharyngeal stenosis after UPPP were reported. Results: One case of local surgery and laser stenosis failed, one case of mucosal flap and nasopharyngeal support was successfully treated. No recurrence was observed at 20 months. CONCLUSIONS: Nasopharyngeal stenosis is associated with more excision of the velopharyngeal arch after UPPP, and prolonged hemostasis in the nasopharyngeal mucosa at the entrance to the mucosa and the inappropriate use of laser. Nasopharyngeal stenosis treatment is difficult, prevention is the best treatment.
