自1974年8月以来,作者们已作同种异体听骨-鼓膜移植术27例。本文统计19例的效果,其中17例已获完整鼓膜;60％以上提高了听力。作者们同意Marquet等观点,认为这种手术适应范围较小:1.以解剖为依据:鼓膜完全缺失及发育不全。2.以病理为依据:严重的鼓膜硬化、粘连性中耳炎及破坏性胆脂瘤。3.乳突术后的术腔重建。4.乳突根治失败者。 Since August 1974, the authors have performed allograft bone-eardrum transplantation in 27 cases. This article statistics the effect of 19 cases, of which 17 cases have been completely eardrum; more than 60% improved hearing. The authors agree with Marquet et al. That this surgical adaptation is small: 1. On the basis of anatomy: complete absence of tympanic membrane and hypoplasia. 2. Pathology as the basis: severe tympanic sclerosis, otitis media and destructive cholesteatoma. 3 mastoid surgery after reconstruction. 4. Mastoid radical failure.
