摘要:: 目的探讨内镜下经外耳道鼓膜成形术的临床效果. 方法 2001年8月～2004年5月,耳内镜下经外耳道鼓膜成形术26例(27耳).外植法刮除鼓膜穿孔周边3 mm上皮层,内植法刮除穿孔周边3 mm内层黏膜,同时刮除穿刺孔缘上皮,鼓室内衬明胶海绵.将修补材料平铺于移植床上(外植法)或衬于穿孔鼓膜下方(内植法),明胶海绵固定移植物,外耳道内填碘仿纱条. 结果鼓膜成形术不做辅助切口,均在内镜下顺利完成,外植10耳,内植17耳.手术时间20～50 min,(30±5) min.26例术后住院1～3 d.26例术后随访1～2个月,移植膜成活良好25耳,2耳不成活,移植膜成活率92.6%(25/27). 结论内镜下经外耳道鼓膜成形术简单、创伤小、术后恢复快、疗效好.

Abstract:: Objective　To evaluate clinical effects of endoscopic transcanal myringoplasty.　M ethods　Endoscopic transcanalmyringoplastywas conducted in 26 cases (27 ears) from August2001 toMay 2004.
