Plain X-ray for locations of intracochlear electrode arrays during cochlear implantation / 临床耳鼻咽喉头颈外科杂志

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 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.
