Image-Guided Cochlear Implant Programming

Cochlear implantation (CI) is the gold standard therapy to restore hearing to individuals with bilateral severe to profound hearing loss. While the vast majority of patients perform well, there is a small subset that do not. Audiologists work extensively with these patients to fine tune the implant’s electrode stimulation plan to optimize their hearing performance. If their hearing performance does not improve, however, there are few other options available.

In collaboration with Vanderbilt University, we are performing a research study using image guidance to change CI stimulation plans (or maps) in hope of improving performance. Based on information from pre-operative and post-operative CT scans we are able to determine the CI electrode position relative to the hearing nerve and identify the area of the hearing nerve each individual electrode stimulates. Using this data, we can create a new CI stimulation plan that we believe will improve hearing performance. We are currently enrolling patients for this study.
