摘要
目的探讨X线摄片对人工耳蜗植入效果不良的原因分析和处理的指导作用。方法对6例人工耳蜗植入效果不良的患者行耳蜗X线平片或加拍CT片检查,并根据各不同情况作相应处理。结果病例1和2的X线耳蜗平片显示电极位于蜗外,取出电极并再行植入术;病例3和4分别显示9个和4个电极位于蜗外遂关闭蜗外电极;病例5显示蜗内有6个电极弯折,关闭弯折处电极并采用双通道方案调试;病例6经拍片证实电极位于蜗内呈园盘状,无弯折。6例患者皆获得满意效果。结论人工耳蜗术后常规进行耳蜗位X线平片检查可了解电极位置及形态,利于指导调试工作。
Objective To know the position and shape of implanted electrode array with plain X-ray after cochlear implantation.Methods According to the Cochlear View developed by Xu plain X-ray was taken post-operatively to obtain the best view of electrode array.Results The Medical imaging of plain X-ray taken before switching on or following the concerning of the performance could assist in the detection of electrode arrays in improper position,partial insertion or bending inside the cochlea.It helped audiologists to make decisions to switch off affected electrodes for the optimization of the program,if functioning electrodes were insufficient and recipients failed.Conclusion It is recommended to conduct post-operative X-ray examination routinely for cochlear implant recipients.Audiologists should be able to use medical imaging to identify the position of intra-cochlear electrodes and apply the information to guide the mapping work.
