Analysis of speech performance in cochlear implant users

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to retrospectively analyze speech perception results from users of the HiRes Ultra and HiRes Ultra 3D cochlear implants. It will collect data on the performance of these devices as measured in clinical settings. The study focuses on both newly implanted users and those who have transitioned from an older version of the device due to failure. By evaluating real-world outcomes, the study seeks to confirm the effectiveness of these cochlear implants in improving speech performance.
