目的了解耳蜗的膜迷路结构,为人工耳蜗手术植入电极做好术前准备。方法分析11例双耳极重度感音神经性耳聋的MRI内耳水成像图像。使用GE Signa Infinity TwinSpeed 1.5T扫描仪,采集内耳所在区域内水信号,送AW4.0工作站进行图像的后处理。结果双耳极重度感音神经性耳聋10例显示耳蜗的膜迷路正常,1例双侧耳蜗只显示一圈半,且耳蜗直径缩小,诊断为耳蜗骨化。结论MRI内耳水成像能清晰显示耳蜗的膜迷路,为人工耳蜗植入电极提供保障。
Objective To understand the labyrinthine membrane labyrinthine structure for cochlear implantation of electrodes for preoperative preparation. Methods Eleven patients with severe sensorineural hearing loss in both ears and ears were analyzed. Using the GE Signa Infinity TwinSpeed 1.5T scanner, water signals were collected from the area of the inner ear and sent to the AW4.0 workstation for image post-processing. Results 10 cases of severe binaural sensorineural deafness showed normal cochlear labyrinth, 1 case of bilateral cochlear showed only one and a half laps, and cochlear diameter was reduced, the diagnosis of cochlear ossification. Conclusion MRI of inner ear water imaging can clearly show the labyrinthine membrane labyrinth and provide cochlear implant electrode protection.
