    Area of Science:

    • Otorhinolaryngology
    • Biomedical Engineering
    • Neuroscience

    Background:

    • Traditional cochlear implant surgeries often require invasive procedures.
    • Developing less invasive techniques is crucial for patient outcomes and recovery.
    • The Cologne-Düren Research Group has focused on extracochlear approaches for a decade.

    Purpose of the Study:

    • To develop and evaluate a noninvasive cochlear implant technique.
    • To avoid surgical opening of inner ear cavities.
    • To assess the applicability and patient experience of the developed system.

    Main Methods:

    • Development of a 16-channel electrode system with a
    • hedgehog
    • contact plate.
    • Integration of a microprocessor for individually programmable speech processing.
