Imaging of Cochlear Implants

Part of the Medical Radiology book series (MEDRAD)


Cochlear implantation has become a widely available tool for successful treatment of deafness or severe sensorineural hearing loss in patients who do not receive adequate benefit from hearing aids. Imaging plays an important role in the selection of suitable candidates and in the planning of the surgery. Therefore, preoperative assessment should provide optimal information on the anatomy of the ear with its normal variances and pathology of the temporal bone and auditory pathway. Postoperative imaging (mostly plain X-ray) is the standard of care in most centers to confirm correct intracochlear positioning of the array. Multislice CT-scanning or flat panel CT is done routinely in some centers, but is usually reserved for cochlear implant recipients with suspected complications after the surgery or malfunctioning of the implant. It is also applied in cochlear implant research to get better insights into the working of cochlear implants.
