摘要
目的:探讨CT和MRI在儿童重度感音神经性聋(SNHL)诊断中的价值。方法:对96例重度SNHL患儿进行颞骨高分辨率CT和MRI检查,并进行三维立体成像。结果:15例患儿CT(MRI)显示异常,其中耳蜗不发育(Michel畸形)1例,耳蜗发育不良1例,共同腔畸形1例,Mondini畸形1例,内耳道狭窄及闭锁各1例,蜗神经未发育1例,前庭水管扩大8例;其余81例CT和MRI均未见内耳及内耳道畸形。结论:部分先天性SNHL患儿存在内耳畸形,颞骨高分辨率CT能显示内耳骨迷路畸形,MRI则能显示畸形的迷路内腔及内耳道内前庭耳蜗神经,为制定干预策略及选择治疗方式提供了重要依据。
Objective：To investigate the value of CT and MRI in diagnosing the children with sensorineural hearing loss.Method：Ninty-six cases suspected as severe sensorineural hearing loss were examined by CT/MRI system and 3D reconstruction.Result：Of 96 cases,15 cases were found malformation these malformation included Michel,cochlear hypoplasia,commun cavity,Mondini,inner cannel straitness,cochlear nerve undeveloped and vestibular aqueduct enlargements.Conclusion：There are 15.63% inner ear malformation occurred in sensorineural hearing loss children.CT and MRI of inner ear have a great clinical value in diagnosing children sensorineural hearing loss by learning the anatomy.
