Comparing two fitting strategies for cochlear implants in patients with hearing loss

Comparison of a Bimodal Fitting With Synchronization and a Conventional Bimodal Fitting in Newly Implanted Cochlear Patient. Prospective Monocentric Randomized Double-blind Crossover Study.

Not applicable Interventional MED-EL Elektromedizinische Geräte GesmbH · NCT05898659

This study is testing two different ways to set up cochlear implants and hearing aids together to see which helps adults with hearing loss hear better in noisy situations.

What this trial studies

This study aims to compare two tonotopy-based fitting strategies for bimodal hearing, which involves using a cochlear implant alongside a hearing aid. One strategy includes synchronization between the devices, while the other does not. The primary focus is on evaluating the accuracy of sound localization, speech perception in noise, and overall auditory skills experienced by the subjects. The study will involve adult patients who meet the criteria for cochlear implantation and have experienced total hearing loss for less than five years.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who speak French and meet the criteria for cochlear implantation.

Not a fit: Patients with retro-cochlear pathology or significant residual hearing in the contralateral ear may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance sound localization and speech perception for patients using cochlear implants and hearing aids.

How similar studies have performed: Previous studies on bimodal hearing strategies have shown promising results, indicating potential benefits in sound perception and quality of life.
