摘　　要：目的 就不同内耳畸形人工耳蜗植入特点及效果进行分析,积累经验。方法 1996年1月～2004年5月北京同仁医院共开展多道人工耳蜗植入术410例(410耳),对其中双侧内耳畸形患者82例(82耳)进行回顾性分析,就不同原因内耳畸形的人工耳蜗植入手术特点及术后开机调试特点与耳蜗形态正常的人工耳蜗植入者进行了比较。结果 ①所有内耳畸形患者人工耳蜗植入术后都有听觉;②内耳畸形人工耳蜗术中容易出现井喷;③82例中除2例患者各遗留2对蜗外电极外,其余电极均完全植入蜗内;④术后无面瘫、脑脊液漏等并发症;⑤术后开机调试数值与结构正常植入者接近,无统计学差异(P>0.05);⑥术后经过语训,1年后听力及言语能力均有不同程度的提高。结论 伴有内耳发育畸形的深度感音性聋患者可以行人工耳蜗植入手术,植入效果与耳蜗发育正常患者的人工耳蜗植入效果基本一致,人工耳蜗植入术可以作为伴有内耳畸形的深度感音性聋患者的治疗和康复手段。Objective To describe clinical experiences with multi-channel cochlear implantation in patients with bilateral inner ear malformations. Methods Among 410 patients who received multi-channel cochlear implantations from 1996 to 2004 in Beijing Tongren Hospital, 82 patients were diagnosed with inner ear malformations and implanted. A retrospective analysis was performed about the surgical characteristics and mapping characteristics after implantation. Results (1) All patients had auditory sensations. (2)Gusher was more common than the normal cochlear implantation. (3)The electrodes were inserted in the 'cochleostomy' in full length of 80 Patients, but 2 pairs of electrodes remained outside of 'cochleostomy' in 2 patients. (4) No serious complications occurred after implantation. (5) The impedance of the electrodes, the T level and C level were similar with the normal cochlear implantation. The results had no significant difference in compare with normal cochlear group ( P > 0. 05 ). (6) The abilities of speech discrimination and spoken language were improved through rehabilitation. Conclusions The cochlear implantation can be performed safely in inner ear malformations. The outcome of hearing rehabilitation for patients with inner ear malformations are similar to those children with normal cochlear structure followed the multi-channel cochlear implantation.
