The radiologic evaluation of the temporal bone in cochlear implant candidates can detect malformations of the inner ear in up to 20% of cases. The aim of our study was to analyze and classify malformations of the inner ear in patients with cochlear implants carried out from 2001 to 2009. Malformations of the inner ear, including malformations of the internal auditory canal were detected in 12.7% of children and 3.4% of adults. Mondini dysplasia was most common and occurred in 45% of cases. The surgical procedure had to be adapted according to the individual malformation. Modification of surgical access, management of intraoperative CSF gusher, choice of electrode array, intraoperative imaging and the use of navigation were the most important factors. Rehabilitation results were generally very positive and corresponded to the expectation depending on the duration of deafness, if no additional handicaps were present.
对人工耳蜗植入候选者的颞骨进行放射学评估，在高达20%的病例中可检测到内耳畸形。我们研究的目的是分析和分类2001年至2009年接受人工耳蜗植入患者的内耳畸形情况。在儿童中，12.7%检测到内耳畸形，包括内耳道畸形；在成人中，这一比例为3.4%。Mondini发育异常最为常见，占病例的45%。手术程序必须根据个体畸形情况进行调整。手术入路的改变、术中脑脊液喷射的处理、电极阵列的选择、术中成像以及导航的使用是最重要的因素。如果没有其他额外的残疾，康复结果总体上非常积极，并且与根据耳聋持续时间的预期相符。
