Twenty-two temporal bones subjected to stapedectomy were examined by light microscopy for histological changes in the long process of the incus. In 19 cases a stainless steel wire technique had been used and in three a polyethylene tube operation had been performed. Twenty healthy unoperated ears were examined as controls. In all operated ears fibrosis and reduced vascularity of the mucosa was noted. In the polyethylene tube group, 1 ear showed the growth of new bone into the lumen of the tube and 1 showed minor resorption of the long process of the incus. In the stainless steel wire group bone resorption of the long process of the incus. In the stainless steel wire group bone resporption was seen in 5 cases and 1 incus also showed an area of necrosis adjacent to the tip; 2 of the 5 incudes showed some loss of the lenticular process. The main factor relating to bony resorption in this group was the presence of other histological changes resulting from postoperative inflammation. These findings represent a critical histological examination; the hearing results obtained appear to be good, although full audiometry is lacking.
对22块接受了镫骨切除术的颞骨进行了光学显微镜检查，以观察砧骨长突的组织学变化。其中19例采用了不锈钢丝技术，3例进行了聚乙烯管手术。选取20只健康未手术的耳朵作为对照。在所有手术耳中均观察到黏膜纤维化和血管减少。在聚乙烯管组中，1只耳朵出现新骨长入管腔，1只耳朵显示砧骨长突有轻微吸收。在不锈钢丝组中，观察到5例砧骨长突骨质吸收，1例砧骨尖端附近还出现坏死区域；5例中有2例砧骨豆状突有部分缺失。该组骨质吸收的主要相关因素是术后炎症导致的其他组织学变化。这些发现代表了一次关键的组织学检查；尽管缺乏全面的听力测定，但所获得的听力结果似乎良好。
