MRI在儿童感音神经性聋人工耳蜗植入术前的应用价值

The application value of MRI in the children with sensorineural hearing loss before cochlear implantation

目的:探讨MRI在儿童感音神经性聋(SNHL)人工耳蜗植入术前的诊断价值及其临床应用。方法:回顾性分析80例临床诊断为SNHL拟行人工耳蜗植入术患儿的MRI图像,结合内耳畸形的最新分类标准进行影像学分类诊断。结果:80例(160耳)SNHL患者中内耳畸形152耳,其中耳蜗畸形38耳,前庭畸形33耳,半规管畸形41耳,前庭导水管扩大37耳,内耳道畸形40耳,蜗神经畸形46耳。结论:MRI能对儿童SNHL人工耳蜗植入术前提供详细可靠的解剖学信息,并进行分类诊断,对指导手术方案,评估预后等都具有重要的临床意义。

Objective：To investigate diagnostic value and clinical application of MRI in the children with senso- rineural hearing loss （SNHL） before cochlear implantation. Method： MRI images of 80 children with the diagnosis of SHNL were retrospectively analyzed in combination with the latest classification of inner ear malformation. Result：There were 152 ears of inner ear malformation of 80 cases （160 ears）, including 38 ears of cochlear malfor- mation, 33 ears of vestibular malformation, 41 ears of semicircular canal malformation, 37 ears of vestibular aque- duct enlargement,40 ears of internal auditory canal malformation, and 46 ears of cochlear nerve malformation. Conclusion： MRI can provide detailed and reliable anatomical information for children with SNHL before cochlear implantation, and help to make the classification diagnosis. Therefore MRI is of great clinical significance for oper- ation plan guidance and prognosis assessment.
