The aim of the study was to report the current surgical procedure that has been established on the basis of about 200 implantations with the Combi 40/40+ implant system. The outstanding features of this procedure are the skin incision and the fact that the electrode can be inserted up to a depth of 34 mm into the cochlea. In order to provide better magnetic positioning of the external parts, a flap-reducing technique may be required. For insertion we used a soft surgery method to preserve structures within the cochlea. In some cases we were able to inspect the cochlea with microendoscopes, which helped to prevent electrode kinking, since fibrous obliterations were found before the insertion. For electrode fixation in the mastoid cavity we used bone paté.
本研究的目的是报告基于约200例使用Combi 40/40+植入系统植入手术所确立的当前手术方法。该手术方法的突出特点是皮肤切口以及电极可插入耳蜗达34毫米深度这一事实。为了使外部部件获得更好的磁性定位，可能需要采用皮瓣缩减技术。在植入时，我们采用了轻柔的手术方法以保护耳蜗内的结构。在某些情况下，我们能够使用微型内窥镜检查耳蜗，这有助于防止电极扭结，因为在插入前发现了纤维性闭塞。对于电极在乳突腔中的固定，我们使用了骨糊剂。
