摘要
目的 了解CT、MRI在耳蜗植入前的作用。方法 感音聋患者 6例 ,经颞骨高分辨CT扫描和耳部MRI检查后行人工耳蜗植入术 ,将CT、MRI结果与手术所见进行对比。结果 CT、MRI显示 6例中 8耳存在前庭半规管扩大等多种类型的结构异常 ,中耳、耳蜗窗及耳蜗形态结构正常 ,与手术所见吻合。结论 人工耳蜗植入术前进行CT。
Objective To evaluate the role of CT and MRI before cochlear implantation. Methods The high-resolution axial computed tomographic scanning (HRCT) and the magnetic resonance imaging (MRI) were performed in 6 deaf patients before the implantation. The image findings were compared with what were found at the time of surgery. Results HRCT showed various forms of deformity in 8 of the 12 ears, e.g. those of the vestibule, semicircular canal and the anterior sigmoid. Normal structures of the membranous labyrinth and the 7th and 8th cranial nerves were identified on MRI in all cases. The MRI and CT findings supplemented each other in clinical significance, and they accorded with what were seen in operation. Conclusion Proper radiography plays an essential role in cochlear implantation in respect of the choice of patients and the planning of operation.
