To analyse the characteristics of the revision cochlear implantation （RCI）patients，the cause of the cochlear malfunction，and the choice of RCI operative approach. A total of 39 patients with RCI were enrolled in this study. The cochlear use time, cause of failure and reoperation procedure are recorded and analyzed retrospectively. There were 39 patients accepted cochlear reoperation，the ages ranges from 1 to 28，average age was 7.8 years, median age was 5 years old. The cochlear use time ranges from 1 month to 7 years，average was 2.2 years, median time was 1 year. Thirty-seven patients underwent RCI,30 cases right side and 7 cases left side. The reason of RCI contains device failure (28 cases)，infection (5 cases)，incorrect electrode implantation (3 cases)，facial nerve stimulation (2 cases)，and electrode prolapse (1 case).The choice of RCI procedure was dependent on the first operation procedure,contains facial nerve recess approach (35 cases) and mastoid approach (2 cases).Contralateral implantation was performed in 5 cases, the rest were ipsilateral. RCI has a variety causes and the common reason is trauma and device failure，the RCI should be completed as early as possible to avoid the ossified cochlear and hearing or speech stagnation，the electrode implantation through previous approach is the best method.
分析人工耳蜗植入翻修术（RCI）患者的特点、人工耳蜗故障原因及RCI手术方式的选择。本研究共纳入39例RCI患者。对人工耳蜗使用时间、故障原因及再次手术过程进行回顾性记录和分析。39例患者接受了人工耳蜗再次手术，年龄1至28岁，平均年龄7.8岁，中位年龄5岁。人工耳蜗使用时间1个月至7年，平均2.2年，中位时间1年。37例行RCI，右侧30例，左侧7例。RCI的原因包括设备故障（28例）、感染（5例）、电极植入不当（3例）、面神经刺激（2例）及电极脱出（1例）。RCI手术方式的选择取决于首次手术方式，包括面神经隐窝入路（35例）和乳突入路（2例）。5例行对侧植入，其余为同侧植入。RCI有多种原因，常见原因是外伤和设备故障，应尽早完成RCI以避免耳蜗骨化及听力或言语停滞，经原入路植入电极是最佳方法。
