Our data represent the experience of the largest cochlear implant program in Austria. In conclusion, cochlear implantation is a safe procedure, associated with a low rate of intra- and postoperative complications. Nevertheless, patients should be informed about possible problems and especially about the risk of a reoperation due to device failure.
To evaluate the cause of deafness, the intraoperative findings and the complication rate for all cochlear implant operations performed consecutively between 1994 and 2003 at Vienna General Hospital.
Including all surgeries for bilateral implantation and revision, a series of 342 operations performed on 164 adults (age range 14.5-81 years; mean age 50.79 years) and 128 children (age range 0.75-14 years; mean age 5.00 years) was retrospectively analyzed.
The etiology of deafness was predominantly congenital or progressive (66.89%). The routine mastoidectomy approach was chosen in 300 patients (87.72%) and the suprameatal approach in 42 (12.28%). Intraoperatively, 4 children (2.53%) had a cerebrospinal fluid fistula and 35 patients (10.23%) showed cochlear ossification. Three adults (1.63%) and two children (1.27%) had facial nerves with an aberrant course. The overall complication rate was 12.2%, the rate of major complications was 4.97% and the rate of minor complications was 4.09%. There were no cases of either postoperative meningitis or facial nerve palsy. Both flap necrosis and electrode dislocation occurred in one adult patient (0.54%), but in none of the children. Formation of cholesteatoma was found in one adult (0.54%) and one child (0.63%). The rate of device failure was 7.07% for adults and 13.92% for children.
我们的数据代表了奥地利最大的人工耳蜗植入项目的经验。总之，人工耳蜗植入是一种安全的手术，术中及术后并发症发生率较低。然而，应告知患者可能出现的问题，尤其是因设备故障而再次手术的风险。
评估1994年至2003年在维也纳总医院连续进行的所有人工耳蜗植入手术的耳聋原因、术中发现及并发症发生率。
回顾性分析了包括所有双侧植入和翻修手术在内的一系列342例手术，这些手术的患者包括164名成年人（年龄范围14.5 - 81岁；平均年龄50.79岁）和128名儿童（年龄范围0.75 - 14岁；平均年龄5.00岁）。
耳聋的病因主要是先天性或进行性的（66.89%）。300例患者（87.72%）采用常规乳突切除术入路，42例（12.28%）采用耳道上入路。术中，4名儿童（2.53%）出现脑脊液漏，35例患者（10.23%）有耳蜗骨化。3名成年人（1.63%）和2名儿童（1.27%）的面神经走行异常。总体并发症发生率为12.2%，主要并发症发生率为4.97%，次要并发症发生率为4.09%。没有术后脑膜炎或面神经麻痹的病例。皮瓣坏死和电极移位均发生在1例成年患者中（0.54%），但儿童中均未发生。1例成年人（0.54%）和1例儿童（0.63%）发现胆脂瘤形成。成年人的设备故障率为7.07%，儿童为13.92%。
