    Area of Science:

    • Otorhinolaryngology
    • Biomedical Engineering
    • Audiology

    Background:

    • Hearing aids are crucial for individuals with hearing loss.
    • Existing hearing aid technologies face limitations in sound fidelity and noise reduction.
    • Middle ear implants (MEI) represent an advanced audiological intervention.

    Purpose of the Study:

    • To introduce the development and advantages of partially implantable middle ear implants (MEI).
    • To compare the performance of partially implantable MEI with conventional air conduction hearing aids.
    • To establish a foundation for future wholly implantable MEI systems.

    Main Methods:

    • Development of a partially implantable middle ear implant (MEI) system.
    • Inclusion of an external induction coil and an internal vibrator positioned on the stapes.
