Homograft ossicles have been utilized in reconstructive middle ear surgery since 1964. In the first few years, simple repositioning of the incus was the method used. Due to the shortcomings of this procedure, a sculptured ossicle, the notched incus, was introduced in 1970 and this has gradually evolved into two standardized and reliable prostheses. In 1972 hearing results were published on the first 122 cases. An expanded study in 1977 reported in detail on 361 ears. The current study reports the results of 326 patients operated upon during the 5 year period of 1976 through 1980 and compares them with the previous studies. The overall hearing results are very similar for both series with little change being noted in the failure rate. However, in the successful categories progress seems to have been made in that a greater percentage of the fair to good results has been shifted to the excellent category. A new concept of ossicular reconstructions is demonstrated with the introduction of the notched incus with high and low profile, to compensate for differences in the stapedial mallear relationship.
自1964年起，同种异体听小骨就被用于中耳重建手术。在最初的几年里，采用的方法是简单地重新放置砧骨。由于该手术的缺点，1970年引入了一种雕刻而成的听小骨——带缺口砧骨，并且这种听小骨逐渐演变成两种标准化且可靠的假体。1972年公布了最初122例病例的听力结果。1977年的一项扩展研究详细报告了361只耳朵的情况。本研究报告了1976年至1980年这5年期间接受手术的326例患者的结果，并将其与之前的研究进行比较。两个系列的总体听力结果非常相似，失败率几乎没有变化。然而，在成功类别中似乎有了进展，因为相当一部分“尚可至良好”的结果已转变为“优秀”类别。通过引入高低轮廓的带缺口砧骨，展示了一种新的听骨链重建概念，以弥补镫骨-锤骨关系的差异。
