摘要
目的 :探讨Commoncavity畸形患者人工耳蜗植入后的语言康复效果。方法 :对 6例Commoncavity畸形患者采用经乳突外半规管进路行人工耳蜗植入 ,并与 6例耳蜗发育正常组进行听力情况比较。结果 :32个电极全部植入者 3例 ,2 8个电极植入者 1例 ,2 6个电极植入者 1例 ,2 2个电极植入者 1例。与正常组比较 ,术中术后并发症差异无显著性意义。术中脑脊液多量流出者 2例 ,少量流出 3例 ,无流出 1例。两组术后听力接近 ,均在 30～ 4 0dBHL左右 ,无严重并发症发生 ,大多数患者术后听觉语言康复效果与正常耳蜗者接近 ,少数稍差。长期效果有待进一步观察。结论 :人工耳蜗适用于Commoncavity畸形患者 ,但手术前应进行全面的听力学及影像学评估。
Objective:To report the multi channel cochlear implantation in patients with Common cavity malformation, including surgeries,pre and postoperative hearing assessments as well as outcomes of speech recognition.Method:Multi channel cochlear implantation surgeries have been performed in 6 cases with common cavity malformation in our hospital from May 1995 to May 2002. The transmastoid lateral semicircular canal approach was used in these cases. The postoperative outcomes of these cases are compared with 6 cases of non malformed cochlea as a control group.Result:Among the 6 cases, All 32 electrodes were inserted in 3 cases, 28 electrodes in 1 cases, 26 electrodes in 1 cases, 22 electrodes in 1 cases. The intra and postoperative complications of the surgeries have no significant difference compared with the surgeries of normal cochlea .The intraoperative 'Ozze' occurred in 2 cases, the small CSF flowing occurred in 3 cases and no CSF flowing occurred in 1 case. Postoperative threshold in sound field were 30～40 dB recovery for all cases, and similar to the normal cochlea cases. Most of them received the similar hearing and speech recovery, compared with the result of non malformed group.Only a few had a higher hearing threshold.The remote effect will be evaluated by long term follow up.Conclusion:Multi channel cochlear implantation could be performed in the cases with common cavity malformation, but preoperative hearing assessments and proper images should be done.
