| 摘 要： | 目的:探讨功能性磁共振(fMRI)评价耳蜗前庭神经畸形患者是否有人工耳蜗植入指征的可能性。方法:对1例15岁双侧耳聋患者,在人工耳蜗植入前进行听力学、影像学检查及fMRI综合评估。结果:纯音测听和听觉脑干反应显示患者为双侧极重度感音神经性聋,瞬态诱发性耳声发射双侧均未引出。颞骨薄层CT显示内耳畸形(不全分隔Ⅰ型),MRI斜矢状位重建显示耳蜗前庭神经畸形。fMRI显示左耳给声,1000Hz100dBHL,右侧听皮层被激活;右耳给声,双侧听皮层均未见激活。左侧人工耳蜗植入术后1个月开机,患者对声音有反应。结论:结合听力学和影像学检查,fMRI可评估人工耳蜗植入候选者,尤其是在影像学检查显示患者耳蜗前庭神经发育畸形时,更是一种有效的评估方法。 |

| Abstract: | Objective:To evaluate the feasibility of cochlear implantation by functional magnetic resonance imaging (fMRI) in a patient with cochleovestibular nerve hypoplasia.Method:Audiometry, radiological examination and fMRI of the auditory cortex were performed to a 15-year-old boy with bilateral hearing loss before cochlear implantation.Result:Results of pure tone audiometry and auditory brainstem responses showed profound sensorineural hearing loss(SNHL).Transiently evoked otoacoustic emission was absent on both... |
