OBJECTIVE
To evaluate the position and shape of inserted electrode arrays by plain X-ray during cochlear implantation.
METHOD
Cochlear view of implanted electrode arrays by plain X-ray were observed during operation in 54 patients received cochlear implant.
RESULT
The image in cochlear view could provide the information about position and shape of inserted electrode arrays. The spiral-shape electrode arrays without distortion and folding were found in 52 cases. The complete insertion of intracochlear electrode in these patients were confirmed by surgery. Of 54 cases, the other 2 cases showed improper position and C-shape of intracochlear electrodes, one was partial insertion and the other was bending inside the cochlea. The bending electrode array was reinserted immediately during operation.
CONCLUSION
Routine plain X-ray after inserted electrode during operation was a best way of knowing the shape and depth of the electrode array, especial for the difficult cochlear implantation, and also could avoided anesthetization again.
目的
通过X线平片评估人工耳蜗植入术中植入电极阵列的位置和形态。
方法
对54例接受人工耳蜗植入术的患者在术中通过X线平片观察植入电极阵列的耳蜗位影像。
结果
耳蜗位影像可提供植入电极阵列的位置和形态信息。52例可见螺旋形电极阵列无扭曲、折叠，术中证实这些患者的耳蜗内电极完全植入。54例中，另外2例耳蜗内电极位置不当呈C形，1例为部分植入，另1例在耳蜗内弯曲。术中立即将弯曲的电极阵列重新植入。
结论
术中植入电极后常规行X线平片检查是了解电极阵列形态和深度的最佳方法，尤其对于困难的人工耳蜗植入，还可避免再次麻醉。
