| 摘 要： | 蜗神经发育不良(Cochlear nerve deficiency,CND)是先天性极重度耳聋的原因之一,指蜗神经缺失或蜗神经纤细.CND的诊断主要依靠在3D-核磁中判断蜗神经状态,而由于技术限制,蜗神经往往显示不清.与非CND患者相比,CND患者的人工耳蜗术后效果较差,且部分患者无法从中获益.因此,提高术前CND的诊...

| Abstract: | Cochlear nerve deficiency(CND)is one of the causes of congenital profound hearing loss,referring to an absent or small cochlear nerve.The diagnosis of CND mainly relies on 3D-dimensional magnetic resonance imaging of the cochlear nerve,which is not always clearly visible due to technical limitations.Compared with non-CND patients,patients with CND can have poor outcomes after receiving cochlear implants,and some may not benefit from cochlear implants at all.Therefore,it is very important to improve preoperative diagnosis of CND and accurate imaging diagnosis of CND is a research hotspot in recent years.This article mainly summarizes imaging indicators that can assist in the diagnosis of CND,and reviews their values in predicting cochlear implants outcomes by existing studies. |
