Summary

This study follows 19 adults with hearing loss who already received a cochlear implant that releases a steroid to reduce inflammation. Researchers will check how well the implant works over 5 years by measuring electrical signals and tracking any side effects. The goal is to see if the steroid-releasing implant performs better than the standard version.
