Abstract

Natural hearing can be combined with a cochlear implant to improve sound quality and speech understanding. However, natural hearing frequently deteriorates weeks to months after cochlear implantation. This seems to occur when cochlear fluid buildup (hydrops) or fibrosis within the inner ear disrupts cochlear mechanics. We plan to monitor these processes in patients by recording directly from the cochlear implant, and conduct laboratory experiments to find therapies to alleviate their effects.
