摘要
目的 探讨Mondini畸形患者人工耳蜗植入手术的可行性效果及手术特点。方法 我院自 1996年开展多道人工耳蜗植入术以来 ,截止到 2 0 0 2年 10月已经开展手术 30 0例 ,其中典型的Mondini畸形患者 15例 (2 8耳 )。本组对这 15例 (15耳 )植入手术患者进行回顾性分析 ,就Mondini畸形人工耳蜗植入手术特点、开机调试结果、言语康复与耳蜗形态正常的人工耳蜗植入者进行了比较。任意抽出 15例 (30耳 )耳蜗结构正常的人工耳蜗植入者作为对照组与Mondini畸形者进行比较。结果 ①Mondini畸形术中 11耳出现井喷现象 ,较对照组多见 ,且井喷比较汹涌 ;严重者术中及术后需要使用甘露醇降颅压 ;② 13例 (13耳 )电极全部植入耳蜗内 ,2例 (2耳 )遗留 2对蜗外电极 ;③术后无面瘫、脑脊液漏、脑膜炎等手术并发症 ;④所有Mondini畸形患者人工耳蜗植入术后都有听觉 ;⑤开机调试时电极反应阈值、最大舒适阈值及阻抗值与对照组数值接近 ,经统计学比较差异无显著性 (P>0 0 5 )。术后平均听阈 (35dBHL)与对照组 (30dBHL)无明显区别。结论 人工耳蜗植入可以作为伴有Mondini畸形的双侧深度感音性聋患者的听觉康复手段 。
Objective To describe clinical experiences with multi channel cochlear implantation in patients with Mondini malformation Methods 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 Results 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) Conclusion 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
