摘　　要：目的探讨MRI在内耳畸形儿童人工耳蜗植入术前的评估价值及其临床应用。材料与方法回顾性分析3岁以下56例拟行人工耳蜗植入术的先天性内耳畸形儿童的内耳MRI资料,结合内耳畸形的最新分类标准进行影像学分类诊断。结果 56例(112耳)中内耳畸形107耳,其中耳蜗畸形56耳,前庭畸形68耳,半规管畸形71耳,内淋巴管及内淋巴囊扩大37耳,内耳道发育异常50耳,蜗神经发育不良58耳。结论人工耳蜗植入术前内耳MRI检查可以准确进行内耳畸形的分类诊断,可指导手术方案、术中并发症的预防及预后判断。Objective：To evaluate the value of magnetic resonance imaging（MRI） in congenital inner ear malformations before cochlear implantation surgery.Materials and Methods：MRI of fifty-six children with inner ear malformations who were younger than 3 years old were retrospectively analyzed according to the latest classification criteria.Results：Of all 56 cases（107 ears） inner ear malformations,there were cochlear malformations in 56 ears,vestibular malformations in 68 ears,semicircular canal malformations in 71 ears,large endolymphatic duct and sac syndrome in 37 ears,internal auditory canal malformations in 50 ears,cochlear nerve dysplasia in 58 ears.Conclusion：The congenital malformations of inner ear can be well demonstrated by MRI.Therefore it should be used routinely before cochlear implantation.
