We reviewed 564 tympanoplasties operated upon over an eight year period at the Otologic Medical Group in which tragal cartilage was used to re-establish the sound pressure transfer mechanism. Eighty-six percent of the cases were revisions, and half of these were planned second stage procedures. In the majority of cases the stapes crural arch was missing. The conductive deficit in these cases was reduced to 20 db or less in 67% and 10 db or less in 40%. The commonest single cause of failure was a short prosthesis. There were no instances of cartilage resorption. Extrusion occurred in one case. Tragal cartilage has been more satisfactory than ossicular tissue in many situations. Recently we have been using plastic prosthesis (TORP and PORP) in combination with tragal cartilage and believe that the results will be even better.
我们回顾了在耳科医疗集团八年期间实施的564例鼓室成形术，这些手术中使用了耳屏软骨来重建声压传递机制。86%的病例为翻修手术，其中一半是计划中的二期手术。在大多数病例中，镫骨脚弓缺失。这些病例中的传导性听力损失在67%的患者中降至20分贝或更低，在40%的患者中降至10分贝或更低。最常见的失败单一原因是假体过短。没有软骨吸收的情况。有一例发生了假体挤出。在许多情况下，耳屏软骨比听小骨组织更令人满意。最近我们一直在将塑料假体（全听骨赝复物和部分听骨赝复物）与耳屏软骨联合使用，并相信结果会更好。
