【摘要】 目的:探讨耳蜗X线拍片在人工耳蜗植入术中的临床意义。方法:对54例人工耳蜗植入患者术中常规使用可移动C-臂数字X线拍片机拍片,观察耳蜗电极的形态和植入深度,常规行NRT检查。结果:52例蜗内电极均呈自然螺旋状,无扭曲或打折,拍片显示刺激电极全部植入耳蜗内。2例插入蜗内的电极串呈"C"形,提示电极未能全部插入,其中1例与术中所见一致,为电极植入不全;1例为术中未能发现的蜗内电极扭曲打折。结论:人工耳蜗植入术中常规在电极植入后进行耳蜗X线拍片,对了解电极植入部位和植入深度非常有益,特别是对于电极植入有难度的患者,更应及时拍片,可避免术后再次手术。更多还原

【Abstract】 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 introcochlear 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.更多还原
