摘要: 蜗神经缺陷(cochlear nerve deficiency,CND)指的是蜗神经纤细或者缺失,研究发现其在先天性感音神经性聋患者中发病率约为18%。发病机制尚不明确,听觉干预效果个体差异较大,本文就CND的相关问题进行探讨。Abstract: Cochlear nerve deficiency(CND) is a rare inner ear malformation characterized by a hypoplastic or absent cochlear nerve, resulting in variable hearing loss or total deafness, depending on the quantity of nerve fibers present. About 18% of congenital hearing loss are associated with CND. It is a disease of uncertain cause. The outcome of auditory implant in CND patients varies widely. This article will discuss the related issues of CND.
