Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Biomedical Engineering

Background:

  • Ossified cochlea presents surgical challenges for cochlear implantation.
  • Current implants with single electrode leads offer limited insertion and suboptimal performance.
  • Limited electrode contact in ossified cochleae leads to reduced patient outcomes.

Purpose of the Study:

  • To introduce and evaluate a novel double electrode array system for cochlear implantation in ossified cochleae.
  • To assess the surgical feasibility and audiological benefits of the new electrode design.
  • To improve cochlear implant performance in patients with complex cochlear anatomy.

Main Methods:

  • A dual-array electrode system was developed, with one array in the basal turn and a second in the apical turn.

  • Surgical technique involved posterior tympanotomy, incus removal, and sequential cochleostomies for electrode insertion.
  • The procedure was adapted for ossified cochleae, allowing insertion into the second cochlear turn when patent.

    • Main Results:

    • The surgical procedure was successfully completed in all nine patients without complications.
    • Intraoperative stapedius reflexes were observed, indicating neural integrity.
    • Patients demonstrated improved performance with the double electrode array, despite a pitch scale gap between arrays.

    Conclusions:

    • The nucleus double electrode array is a viable advanced treatment for ossified cochleae.
    • This technology enables increased electrode insertion, potentially maximizing patient benefit.
    • The system integrates with standard nucleus cochlear implant hardware.
