对13例镫骨切除术后的16块颞骨进行了组织学观察。原位假体的照片是研究的一个特点。结果发现，假体与卵圆窗边缘重叠会导致气骨间隙闭合不完全。纤维粘连是中耳粘膜创伤的常见后果。Gelfoam®植入促进薄卵圆窗膜的形成，其倾向于凸出卵圆窗。大多数卵块显示小面积的皮质骨吸收。从这些研究中判断，至少有一半的病例镫骨切除术的手术技术不太理想。进行镫骨切除术的外科医生应该认识到相关的外科病理学，并采取优化功能结果和减少并发症的方法。
Histological studies were made of 16 temporal bones of 13 subjects who had stapedectomy operations. Photographs of the prostheses in situ are a special feature of the studies. It was found that prostheses which overlap the margins of the oval window cause incomplete closure of the air-bone gaps. Fibrous adhesions were a common consequence of trauma to the mucous membrane of the middle ear. Gelfoam® implantation promotes the formation of thin oval window membranes which tend to bulge out of the oval window. Most incudes show small areas of cortical bone resorption. In at least half the cases the surgical technique of stapedectomy, as judged from these studies, was less than ideal. Surgeons who perform stapedectomy should be cognizant of the relevant surgical pathology and adopt methods which will optimize functional results and minimize complications.
