为了寻求镫骨切除术后未能提高听力,甚至引起感觉神经性聋的机理,作者对13例镫骨切除术后的16块颞骨进行了组织学并采用赝复物所在位置的录相的特殊形态研究,所有的标本都是用固定、脱钙、火棉胶包埋、连续切片、HE染色的标准法制备的。组织切片要切在能看到赝复物的平面。除金属装置须先行去除外,对于多氟乙烯(PE)管,聚四氟乙烯(Teflon)、硅橡胶所做的赝复物,可保留在原部位做切片。组织病理学所见:金属丝赝复物与砧骨长突或多氟乙烯管与砧骨连接良好者共13耳,赝复物内侧端接触在卵圆窗边缘者2耳,聚四氟乙烯活
In an attempt to find a mechanism that fails to improve hearing and even sensory nerve deafness following tarsomectomy, the authors performed a histologic study of 13 temporal bones after resection of the laryngectomy and adopted the special recording of the position of the prosthesis Morphological studies, all specimens were fixed, decalcified, collodion embedded, serial sections, HE stained prepared by the standard method. Tissue sections should be cut to the plane where the prosthesis can be seen. In addition to the metal device to be removed first, the polyfluoroethylene (PE) pipe, Teflon, silicone rubber made of prosthesis, can be kept in the original location of the slice. Histopathological findings: a total of 13 ears were connected with a metal mesh prosthesis and an incus or polyfluoroethylene tube and an incus, and the medial end of the prosthesis contacted 2 ears at the edge of the oval window.
