Binaural cochlear implants offer benefits for selected patients seeking improved hearing. While results vary, a second cochlear implant can enhance auditory function without risking a functioning device.

Area of Science:

Otolaryngology
Neuroscience
Biomedical Engineering

Background:

Bilateral cochlear implantation is increasingly explored following successful monaural (single-sided) cochlear implant outcomes.
Patient inquiries regarding a second cochlear implant are common, necessitating evaluation of its efficacy and safety.

Observation:

This study involved 12 adult patients receiving binaural cochlear implants, with contralateral implantation prioritized to avoid disrupting existing devices.
Implant configurations included upgrading to a magnetic receiver (3M/House) or adding a multichannel device (Nucleus), with one patient receiving a second Nucleus device due to poor function.

Findings:

Auditory discrimination was assessed in patients with mixed monaural/binaural configurations, revealing some objective improvements across tests for all participants.

Related Experiment Videos

Five out of six patients regularly used both devices, demonstrating functional benefit from binaural stimulation, even with differing implant technologies (Nucleus and 3M/House).

Implications:

Contralateral cochlear implantation is a viable option for carefully selected patients aiming for implant upgrades.
This approach allows for potential auditory enhancement without compromising the function of an already-implanted ear.
