Overview of safety imaging methods for newly designed cochlear implant electrodes.
Different individual test methods and protocols have been reported for the in-vitro evaluation of temporal bones implanted with newly designed cochlear implant electrodes, prior to human implantation. In practice, however, these methods may not always give the required information. In this study, a large battery of tests has been evaluated using the electrode as a fixed parameter. Standard clinical x-ray gave the best information to evaluate the electrode's position. Light microscopic evaluation and polishing technique studies proved to be the most valuable techniques to evaluate endocochlear damage.
