对鼓膜成形术使用异种和自体材料的成功率进行了回顾性研究。53耳均行鼓膜成形术3年以上,全部手术均系同一个医生操作。第一组43耳鼓膜修补材料为自体颞筋膜自耳后切口取得。第二组10耳采用Zenoderm(经过蛋白溶解酶及戊二酸盐浸泡处理的猪的真皮)作为鼓膜修补材料。全部修补材料均系经外耳道径路平铺于残余鼓膜与槌骨柄之间。两组病人在年龄、鼓 A retrospective study was conducted on the success rate of using ectomymal and autologous materials for tympanoplasty. 53 ears were underwent tympanoplasty more than 3 years, all operations are the same doctor. The first group of 43 eardrum repair materials were obtained from the posterior ear incision for the autologous temporal fascia. The second group of 10 ears used Zenoderm (dermis of pigs treated with proteolytic enzymes and glutaric acid salts) as a tympanic membrane repair material. All repaired materials are tiled between the residual tympanic membrane and the mallet stem via the path of the external auditory meatus. Two groups of patients at age, drums
