    Split electrode array cochlear implantation is effective for ossified cochleas. This method improves auditory performance in both children and adults with profound deafness.

    Area of Science:

    • Otolaryngology
    • Neurosurgery
    • Audiology

    Background:

    • Cochlear ossification presents challenges for hearing restoration.
    • Split electrode arrays offer potential advantages in navigating ossified cochleas.

    Purpose of the Study:

    • To evaluate the efficacy of split electrode array cochlear implantation in ossified cochleas.
    • To assess auditory outcomes using the Category of Auditory Perception (CAP) score.

    Main Methods:

    • Retrospective case study of six cochleae (3 adult, 3 pediatric) with ossification.
    • Cochlear implantation using a split electrode array system.
    • Auditory performance assessed with the CAP score at 1-year follow-up.

    Main Results:

  • Mean inserted electrodes: 18.3; mean functioning electrodes: 14.3.
  • Mean CAP scores at 1 year: 6 for children, 8 for adults.
  • One case of transient facial nerve twitching, managed by electrode adjustment. No facial palsy or vestibular disorders.

    • Conclusions:

    • Split electrode array cochlear implantation yields good auditory outcomes in ossified cochleas.
    • The design facilitates greater electrode insertion and potentially reduces facial nerve stimulation.
