耳屏软骨-软骨膜鼓膜成形术的疗效观察

Application of Tragic Cartilage in Myringoplasty with Large Tympanic Perforation

目的探讨耳屏软骨软-骨膜作为移植材料用于鼓膜大穿孔修补术的临床效果。方法对我院2006年4月～2009年4月收治的96例（96耳）鼓膜紧张部大穿孔病例，采用自体耳屏软骨-软骨膜作为移植材料完成I型鼓室成型术，所有病例均采用内植法I期完成，并与同期用颞肌筋膜修补的82耳相同病变进行比较。术后对鼓膜愈合情况、听力恢复效果等进行定期观察。结果软骨-软骨膜复合物行鼓膜修补术鼓膜愈合的长期有效率为97．9％（94/96）；颞肌筋膜组为96.3%（79/82）。两组的听力结果差异无统计学意义。随访2年，听力检测结果稳定。结论对于紧张部大穿孔的病例采用耳屏软骨-软骨膜复合物行鼓膜修复术是可行的，并获得满意的听力效果。

Objective To summarize the clinical application of autogenous cartilage in large tympanic perforation. Methods We retrospectively analyzed 96 cases of myringoplasty with large perforation by autogenous tragic cartilage performed between April 2006 and April 2009.The result was compared with that of the temporal fascia myringoplasty at the same time. Results All patients were followed up more than l year.The closing rate of autogenous tragic cartilage myringoplasty was 97.9%（94/96）. The closing rate of temporal fascia myringoplasty was 96.3%（79/82）. There was no significant difference between the two groups. Conclusion Myringoplasty with tragus cartilage is a useful technique for tympanic membrane perforations.
