【摘要】 目的 探讨耳内镜下超薄耳屏软骨-软骨膜修补鼓膜大穿孔的效果。方法 回顾性分析31例应用超薄耳屏软骨-软骨膜行耳内镜下夹层法鼓膜修补术的患者资料，随访6个月，分析术后鼓膜愈合率、听力恢复情况。结果 30例鼓膜愈合，成功率96.8%，无移植物外移、内陷、钝角愈合；术前平均气导听阈为（38.3±3.3）dB HL，骨气导差为（23.5±3.1）dB HL，术后平均气导听阈为（22.3±1.6）dB HL，骨气导差为（6.3±2.5）dB HL，听力较术前提高（P<0.001）。结论 超薄耳屏软骨-软骨膜在耳内镜下鼓膜大穿孔修补术中效果较好，并发症少，是可靠的修复材料，值得临床推广应用。更多还原

【Abstract】 Objective To investigate the clinical efficacy of endoscopic ultrathin tragus cartilage-perichondrium as graft material for treatment of large tympanic membrane perforations.Methods A total of 31 cases(31 ears)which were diagnosed as chronic suppurative otitis with large tympanic membrane perforation were performed endoscopic myringoplasty with ultrathin tragus cartilage-perichondrium by sandwich technique.The pure tone threshold average(PTA)of speech frequency and the air-bone gap were assessed at 6 month safter surgery.Results Successful closure without reperforation was obtained in 30 of 31 patients(96.8%).There was no graft lateralization,anterior blunting.Average postoperative air conduction and bone-air conduction gap were(22.3±1.6)dB HL and(6.3±2.5)dBHL compared with(38.3±3.3)dB HL and(23.5±3.1)dB HL preoperatively(P<0.001).Conclusions The ultrathin tragus cartilage-perichondrium is liable repair material for large tympanic membrane perforation with excellent graft take and significant improvement of hearing,which is worthy of clinical promotion.更多还原
