目的探讨自体软骨-软骨膜复合移植在中耳乳突手术中的应用前景。方法应用自体耳屏软骨-软骨膜复合移植行鼓室成形手术20倒。结果术后6个月随访，移植成功率95％；气-骨导间距在20dBHL以内17例85％，其中气一骨导间距在10dBHL以内者11例占55％。结论自体软骨－软骨膜是一种有前途的中耳乳空手术修复材料，值得进一步研究。
Objective To explore the application of autologous cartilage-cartilage composite graft in the treatment of middle ear mastoid surgery. Methods The application of trabeculectomy cartilage - perichondrial composite transplation tympanoplasty 20 down. Results The follow-up of 6 months after operation was 95%. The gas-bone conduction distance was within 20 dBHL in 17 cases and 85%. Among them, 11 cases (55%) had air-bone conduction within 10 dBHL. Conclusion Autologous cartilage - perichondrium is a promising material for repairing otolaryngology, which deserves further study.
