    Summary

    Single-electrode cochlear implants significantly improve hearing thresholds and sound awareness for profoundly deaf adults. These devices offer a viable alternative to hearing aids, enhancing speechreading and voice monitoring capabilities.

    Area of Science:

    • Audiology
    • Otolaryngology
    • Biomedical Engineering

    Background:

    • Profound deafness presents significant challenges for auditory perception and communication.
    • Conventional hearing aids offer limited benefit for individuals with profound hearing loss.

    Purpose of the Study:

    • To evaluate the audiological performance of single-electrode cochlear implants in profoundly deaf adults.
    • To compare implant performance against unaided and hearing aid conditions.

    Main Methods:

    • Audiological testing of 135 adult subjects with profound deafness and single-electrode cochlear implants.
    • Analysis of warble-tone and speech detection thresholds.
    • Assessment of word, word stress, and environmental sound discrimination scores.

    Main Results:

    • Cochlear implants demonstrated significantly better thresholds than hearing aids across all tested frequencies and for speech detection.
    • Word, word stress, and environmental sound discrimination scores were significantly higher with cochlear implants compared to hearing aids.
    • Subjects reported enhanced speech and sound awareness, aiding speechreading and voice monitoring, despite limited speech discrimination.

    Conclusions:

    • Single-electrode cochlear implants are a viable audiological rehabilitation option for profoundly deaf individuals.
    • The implants provide substantial benefits in sound awareness and audibility, complementing existing hearing aid use.
    • Combined cochlear implant and hearing aid use in different ears shows potential for improved outcomes.
