Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Neurosurgery

Background:

  • Ossified and dysplastic cochleas present unique surgical and programming challenges for cochlear implant (CI) procedures.
  • Altered embryology and physiology in these conditions lead to complex anatomical variations.
  • Historically, these cases were often excluded from cochlear implantation.

Purpose of the Study:

  • To review the challenges and advancements in cochlear implantation for patients with ossified and dysplastic cochleas.
  • To highlight how technological and surgical progress has expanded eligibility for these patients.

Main Methods:

  • Review of diagnostic imaging techniques for labyrinthine ossification and dysplasia.
  • Analysis of surgical approaches and electrode designs tailored for complex cochlear anatomy.
