NCT ID NCT04707885
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether a special monitoring tool called electrocochleography can help surgeons preserve a patient's remaining natural hearing while placing a cochlear implant. About 40 adults with severe hearing loss in both ears will be randomly assigned to receive the monitoring or standard surgery. Researchers will measure hearing levels over two years to see if the device makes a difference.
