    Area of Science:

    • Otorhinolaryngology
    • Biomedical Engineering
    • Neuroscience

    Background:

    • Sensorineural hearing loss significantly impacts quality of life.
    • Cochlear implants are established treatments for severe to profound hearing loss.
    • Advancements in implant technology aim to improve auditory perception.

    Purpose of the Study:

    • To evaluate the efficacy of a newly designed unichannel extracochlear implant.
    • To assess the auditory information provided by the experimental implant.
    • To determine the potential benefits for patients with total deafness.

    Main Methods:

    • A unichannel extracochlear implant was designed and fabricated in-house.
    • The implant was surgically implanted in several patients with total deafness.

  • Auditory perception and information transfer were assessed post-implantation.

    • Main Results:

    • Consistent results were observed across all implanted patients.
    • The implant provided very rudimentary auditory information.
    • This basic auditory feedback was found to be helpful for the target patient group.

    Conclusions:

    • The laboratory-designed unichannel extracochlear implant demonstrates potential for providing basic auditory sensation.
    • The implant's ability to deliver rudimentary auditory information may assist totally deaf individuals.
    • Further research and development are warranted to enhance implant performance and expand clinical application.
