Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Surgical Innovation

Background:

  • Cochlear implantation (CI) is a standard surgical treatment for severe to profound sensorineural hearing loss.
  • Traditional CI surgery often involves mastoidectomy, which can lead to complications.
  • Endoscopic techniques offer potential advantages in minimally invasive surgery.

Purpose of the Study:

  • To assess the feasibility of an endoscopic technique for cochlear implant (CI) positioning.
  • To evaluate the benefits and drawbacks of endoscopic CI without mastoidectomy.
  • To describe the surgical procedure and analyze outcomes.

Main Methods:

  • Prospective case series of six patients undergoing endoscopic CI.
  • Detailed description of surgical steps, focusing on round window (RW) niche anatomy.

  • Analysis of intra- and post-operative complications and surgical duration.

    • Main Results:

    • The average surgical time was 120 ± 21 minutes.
    • Endoscopic identification and magnification of the RW niche were successful in all cases.
    • Complications included one intra-operative chorda tympani injury; no post-operative complications were reported.

    Conclusions:

    • Endoscopic CI is a safe and viable surgical technique.
    • It avoids mastoidectomy and demonstrates a low complication rate.
    • The procedure yields good outcomes for cochlear implant positioning.
