    A new multi-electrode cochlear implant designed for children has been successfully implanted in two young patients. This device enables determination of hearing levels, aiding in auditory rehabilitation for pediatric hearing loss.

    Area of Science:

    • Biomedical Engineering
    • Otolaryngology
    • Neuroscience

    Background:

    • Pediatric hearing loss impacts language development.
    • Current cochlear implant technology requires adaptation for young children.
    • A novel multi-electrode intracochlear implant (ICI) has been developed.

    Purpose of the Study:

    • To evaluate the feasibility and efficacy of a new multi-electrode ICI in young children.
    • To assess the implant's performance in determining auditory thresholds.
    • To initiate a training and assessment program for pediatric implant users.

    Main Methods:

    • Design of a smaller, child-friendly multi-electrode ICI with 21 stimulus channels.
    • Surgical implantation in two children (aged 5 and 10) with pre-lingual hearing loss.

  • Determination of threshold and comfortable listening levels for each electrode pair, aided by visual and electrotactile stimulus training in the younger child.

    • Main Results:

    • Successful implantation and regular use of the ICI by both pediatric patients.
    • Ability to determine threshold and comfortable listening levels for individual electrode pairs.
    • Facilitation of auditory assessment through specialized training methods.

    Conclusions:

    • The novel multi-electrode ICI is suitable for pediatric use.
    • The device allows for effective audiological assessment in young children.
    • Ongoing training and assessment are crucial for optimizing outcomes in pediatric cochlear implantation.
