Summary

This study demonstrates a successful one-step surgical technique for cochlear implantation in patients with chronic suppurative otitis media. This approach obliterates the radical cavity, creating an infection-free site for profound hearing loss treatment.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Medical Devices

Background:

  • Chronic suppurative otitis media (CSOM) with radical cavities historically contraindicated cochlear implantation due to complication risks.
  • Previous complications included cavity infection, fat necrosis, skin flap issues, electrode displacement, and cholesteatoma.
  • Maintaining an infection-free surgical site is critical to prevent cochlear damage and preserve neural elements.

Purpose of the Study:

  • To evaluate a one-step surgical technique for obliterating radical cavities and performing cochlear implantation simultaneously.
  • To establish a dry, self-cleansing, and infection-free cavity in patients with CSOM undergoing cochlear implantation.

Main Methods:

  • A cohort of eight patients with long-term bilateral chronic middle ear disease and sepsis underwent the one-step procedure.

  • The technique involved obliterating the radical cavity followed by cochlear implant insertion.
  • Surgical outcomes and complications were monitored.

    • Main Results:

    • The one-step surgical technique was successfully performed in all eight patients.
    • No major complications were reported in the postoperative period.
    • The procedure effectively created a suitable environment for cochlear implantation.

    Conclusions:

    • A one-step surgical technique for radical cavity obliteration and cochlear implantation is feasible and safe.
    • This approach addresses previous contraindications for cochlear implantation in patients with CSOM.
    • The technique offers a viable solution for treating severe hearing impairment in this patient population.
