中耳重建术的效果可有很大差异。Austin,Shea,以及Fisch所设计的全听骨赝复物在顶盖的形状、顶盖与赝复物小柱相接的位置上,均有不同变化,但对赝复物放置于镫骨底板或卵圆窗上的位置则很少注意。通过对中耳解剖学和物理学复习,认为使全听骨赝复物的机械力学适合于镫骨底板是非常重要的。在正常声级的声刺激时,镫骨以后韧带为枢纽,自前向后有效地摆动。因此,有效的全听骨赝复物应使赝复物底板的接触能仿效这种运动。它将决定通过全听骨赝复物和镫骨内面的机械效率。
The effect of middle ear reconstruction can vary widely. Austin, Shea, and Fisch designed all ossicles prosthesis in the shape of the top cover, cap and prosthesis posts connected to the location, have different changes, but the prosthesis placed in the stapes floor Or oval window on the location of the little attention. Reviewing the anatomy and physics of the middle ear, it is important to consider the mechanics of a full-bony prosthesis for the stapes floor. Acoustic stimulation in the normal sound level, after the ligament of the stapes as a hub, effectively swing from front to back. Therefore, an effective pan-bone prosthesis should allow contact with the prosthesis floor to follow this movement. It will determine the mechanical efficiency of the bone prosthesis and tarsal bone by listening to it.
