本文介绍1968—1975年应用同种鼓膜、听小骨单独移植或联合移植后在解剖、听力方面所取得的成果。早先的技术是采用外耳道皮瓣覆盖移植的同种异体鼓膜。1969年曾尝试了其他的新技术。但这种尝试导致移植的失败显著增加,因此作者又迅速回到原先的技术,并使用于全过程。包括1969年的头4年,移植成功率为92％;第二部分增至96％。听力的改善在这两个时期内具有较大差异。最后4年有89％的病人获得满意的听力效果(第一阶段仅77％)。
This article describes the application of the same type of tympanic membrane from 1968 to 1975, listening to the results of the anatomy and hearing after a single bone graft or combined transplantation. Earlier techniques used external ear canal flaps to cover transplanted allogeneic eardrums. In 1969 tried other new technologies. However, this attempt led to a significant increase in the failure of transplantation, so the author quickly returned to the original technology, and used in the whole process. Including the first four years of 1969, the transplant success rate was 92%; the second part increased to 96%. The improvement of hearing in these two periods have great differences. In the last 4 years, 89% of patients achieved satisfactory hearing effects (only 77% in stage 1).
