    Cochlear implants help totally deaf patients hear but sounds are distorted. While improving lipreading and safety, further research is needed for better speech discrimination.

    Area of Science:

    • Otorhinolaryngology
    • Biomedical Engineering
    • Neuroscience

    Background:

    • Sensorineural hearing loss significantly impacts communication and safety.
    • Cochlear implantation offers a potential solution for profound deafness.
    • Single-channel electroacoustic stimulation represents an early approach in cochlear implant technology.

    Purpose of the Study:

    • To present the patient selection, surgical approach, and outcomes of cochlear implants.
    • To evaluate the efficacy of analogue single-channel electroacoustic stimulators.
    • To assess the impact of cochlear implants on sound perception, speech discrimination, and lipreading.

    Main Methods:

    • Cochlear implantation in 16 patients using plug-type (12) and coil-type (4) electrodes.
    • Utilized analogue single-channel electroacoustic stimulators.

  • Follow-up duration ranged from 8 months to 3 years.

    • Main Results:

    • Patients regained sound awareness, aiding safety and lipreading.
    • Auditory perception was distorted, limiting speech discrimination.
    • Outcomes were encouraging, indicating potential for auditory rehabilitation.

    Conclusions:

    • Current cochlear implant technology can reintroduce sound to profoundly deaf individuals.
    • Significant limitations in speech discrimination persist, necessitating further technological advancements.
    • Continued research and development are crucial for improving cochlear implant performance.
