The Role of Plain X-Ray Aiding Cochlear Implant / 听力学及言语疾病杂志

ABSTRACT

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 postoperatively 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.
