Otol Neurotol:电听力脑干响应来评估耳蜗神经功能的有效性研究

2017-10-30 AlexYang MedSci原创

最近,有研究人员利用耳蜗内测试点击来评估耳蜗移植(CI)受试者听觉神经的完整性和功能情况,并且比较了通过测试电极获得的电听力脑干响应(eABR)和CI的eABR响应。地点在一个耳鼻喉科学部的三级转诊医院。研究包括了10名参与者,耳蜗移植平均年龄为55岁,范围为19-72岁,并且这些参与者随后在没有任何有用的残余听力侧植入了 MED-EL CONCERTO CI。研究人员利用 Walton et a

最近,有研究人员利用耳蜗内测试点击来评估耳蜗移植(CI)受试者听觉神经的完整性和功能情况,并且比较了通过测试电极获得的电听力脑干响应(eABR)和CI的eABR响应。地点在一个耳鼻喉科学部的三级转诊医院。研究包括了10名参与者,耳蜗移植平均年龄为55岁,范围为19-72岁,并且这些参与者随后在没有任何有用的残余听力侧植入了 MED-EL CONCERTO CI。

研究人员利用 Walton et al. (2008)的得分标准对eABR波形质量进行了评估,并通过波形的算法和可视化评估对第III波段和第V波段进行了检测,从而对每个区段的波形进行分类,另外,研究人员还利用单音节词、双音节词和句子识别测试对受试者的语言表现进行了评估。

研究发现,在所有受试者中,通过测试电极和CI都能够激发出电刺激。在测试电极和CI中,研究人员并没有发现刺激后潜伏期和振幅的显著差异。所有受试者利用CI都获得了有用的听力,并且经常使用植入物。最后,研究人员指出,耳蜗内测试电极通过记录eABR信号,也许对测试听觉神经的完整性是合适的。更深的研究需要关注肿瘤移除后的听觉状态以及与听觉表现的关系。

Laryngoscope:耳蜗移植对中耳功能影响的研究

为了确定术前和术后3个月时间点上,是否耳蜗移植对移植的和对侧的对照耳朵对中耳传导性听力机制具有延迟效应,研究人员通过测量鼓膜的激光多普勒测振(LDV)对其进行了分析,并且分析比较了移植耳朵和对照耳朵的LDV测量结果的相对变化。研究是一个前瞻性的群体研究。研究包括了11名术前成年人单边耳蜗移植受试者,并且之前并没有进行外科手术且具有正常的解剖结构,充气颞骨同样包括在此研究中。另外,研究人员在手术前和
