著者提出:利用自体听骨或同种异体听骨重建鼓室传音机构比利用膺复物好,从远期效果来看更是如此。移植同种的听骨可以和宿主组织长在一起,能取得移植自体听骨同样的效果。早期移植同种砧骨的方法是把砧骨长脚截去,将砧骨短脚与镫骨头接触,后来改为砧骨短脚与镫骨底板接触,但仍存在某些缺点,如:砧骨短脚长度不够、短脚过宽不能放入狭窄的前庭龕、愈合过程中难以保持适当的位置等。以后又改为将砧骨长脚与镫骨底板接触,长脚虽有足够长度,适用于多数病例,但也存在缺点.如:放置过程或愈合过 The authors propose that the use of autologous cannon or alloskeleton reconstruction tympanic sound institutions than the use of prosthetic complex is good, from the forward effect point of view even more so. Transplantation of the same kind of ossicles and host tissues can grow together to obtain the same effect of transplanting autologous ossicles. Early transplantation of the same incus method is to cut off the long incarceration of the incus, the short incarceration of the incarceration with the tarsal head, and later the incarceration of the short foot and the tarsal floor contact, but there are still some disadvantages, such as: anvil Bone short foot length is not enough, short legs too wide can not be placed in a narrow vestibule, the healing process is difficult to maintain proper position. Later, the incarceration of the long foot and the stapes floor was changed. Although the long legs were long enough for the majority of cases, they also had disadvantages such as placement or healing
