To describe clinical experiences with multi-channel cochlear implantation in patients with Mondini malformation.
Among 300 patients who received multi-channel cochlear implants from 1996 to 2002 in Beijing Tongren Hospital, 15 patients were diagnosed with Mondini malformation. A retrospective analysis was performed dealing with the surgical techniques, mapping and rehabilitations characteristics after surgery. 15 patients with normal cochlear structure are consider as control group.
Gusher is found more common than the normal cochlear implantation, most of them are serious. The electrodes are inserted in the "cochleostomy" in full length of 13 Patients, 2 pairs of electrodes remains outside of "cochleostomy" in 2 patients. No serious complications occurred after implantation. All patients have auditory sensations. The impedance of the electrodes, the T level, C level and the hearing threshold are similar with the normal cochlear implantation group. The results have no significant difference in compare with normal cochlear group(P > 0.05).
Multi-channel cochlear implantation could be performed safely in patients with Mondini malformation. The primary outcome for patients with Mondini malformation are similar to those with normal cochlear structure following the multi-channel cochlear implantation.
描述蒙迪尼畸形患者多通道人工耳蜗植入的临床经验。
1996年至2002年在北京同仁医院接受多通道人工耳蜗植入的300例患者中，15例被诊断为蒙迪尼畸形。对手术技术、术后调机及康复特点进行回顾性分析。将15例耳蜗结构正常的患者作为对照组。
发现“井喷”现象比正常人工耳蜗植入更常见，且多数严重。13例患者电极在“蜗开窗”处全长插入，2例患者有2对电极留在“蜗开窗”外。植入后未发生严重并发症。所有患者均有听觉感受。电极阻抗、T值、C值及听阈与正常人工耳蜗植入组相似,与正常耳蜗组比较差异无统计学意义（P>0.05）。
蒙迪尼畸形患者可安全地进行多通道人工耳蜗植入。多通道人工耳蜗植入后，蒙迪尼畸形患者的主要结果与耳蜗结构正常的患者相似。
