耳屏软骨-软骨膜在开放式鼓室成形术中的临床应用

The application of tragal cartilage-perichondrium in open method tympanoplasty

目的:探讨耳屏软骨-软骨膜复合体在开放式鼓室成形术中的疗效。方法:选择行开放式鼓室成形手术的30例(30耳)中耳胆脂瘤患者,术中使用经塑形的耳屏软骨-软骨膜修复鼓膜,钛人工听小骨重建听骨链,观察术后气骨导差及鼓膜恢复情况。结果:30例术耳均一期愈合,无听骨脱出及上鼓室塌陷,术后气骨导差平均较术前缩小13dB。结论:耳屏软骨-软骨膜是开放式鼓室成形伴听骨链重建术中的理想修复材料,值得临床应用。

Objective：To investigate the efficacy of the application of tragus cartilage-perichondrium in open method tympanoplasty. Method：Thirty patients with middle ear cholesteatoma were treated with open method tym- panoplasty and titanium ossicular prosthesis replacement surgery utilized the tragus cartilage-perichondrium, the air-bone gap and the recovery of tympanic membrane were observed before and after operation. Result ： Thirty ears achieved primary healing. After a follow-up of 12 months, no prosthesis extrusion and atticus lateral wall collapse were observed. The average air-bone gaps reduced by 13 dB in average. Conclusion：The tragus cartilage-perichon- drium is an appropriate material in open method tympanoplasty.
