背景高分辨率磁共振成像能够显示内听道(IAC)中的单个神经。耳蜗神经缺陷(CND)被认为是感觉神经性听力损失(SNHL)的主要原因之一，尤其是在儿童单侧听力损失的情况下。一些CND患者被认为伴有前庭神经缺乏症(VND)。材料与方法38例经3 T-MRI确诊的单侧听神经元性听神经痛患儿，对其进行了听神经性听神经病的诊断，并进行了冷热试验和颈前庭诱发电位检查。伴有VND的患者听力明显低于无VND的患者，IAC直径较小。结论及意义CND听力损失患者除注意前庭功能障碍外，还应注意VND。
BackgroundHigh-resolution MR imaging enables the visualization of individual nerves in the internal auditory canal (IAC). Cochlear nerve deficiency (CND) is recognized as one of the major causes of sensory neural hearing loss (SNHL), especially in cases of unilateral hearing loss in childhood. Some patients with CND are thought to have accompanying vestibular nerve deficiency (VND). However, there have been few reports focusing on VND and vestibular function in these children.AimsThe aim of this study was to evaluate the frequency of VND and vestibular dysfunction in children with unilateral SNHL caused by CND.Material and MethodsThirty-eight children with unilateral SNHL, who were diagnosed with CND by 3 T-MRI, were evaluated for VND and underwent caloric testing and cervical vestibular evoked potential (cVEMP).ResultsFourteen of 38 patients (37%) had VND, and eleven (29%) of the patients [ten of the patients (71%) with VND] had at least one vestibular dysfunction. The patients with VND had significantly worse hearing and an IAC of smaller diameter than did patients without VND.Conclusions and significanceWe should pay attention to VND as well as vestibular dysfunction in hearing loss patients with CND.
