Clinical and experimental data appear to indicate that by means of an extremely gentle procedure, known as the "soft surgery" technique, during the insertion of the electrode carrier of the cochlear implant, some level of existing residual hearing can be preserved. By means of an animal model, morphologic changes in the organ of Corti after use of this atraumatic implantation technique were investigated with two types of implants and the results compared. Insertion of the implants was facilitated by lubrication with Healon. In the scanning electron microscopy picture of the organ of Corti, only minor changes in the outer hair cells were observed. As an obligatory reaction of the cochlea to the intracochlear implant, a connective tissue envelope was found around the electrode carrier.
临床和实验数据似乎表明，通过一种极为温和的程序，即所谓的“软手术”技术，在植入人工耳蜗电极载体的过程中，可以保留一定程度的现有残余听力。借助动物模型，使用这种无创植入技术后，对两种类型的植入物研究了柯蒂氏器的形态变化，并比较了结果。通过用透明质酸钠润滑来促进植入物的插入。在柯蒂氏器的扫描电子显微镜图像中，仅观察到外毛细胞有轻微变化。作为耳蜗对人工耳蜗植入的必然反应，在电极载体周围发现了结缔组织包膜。
