The pericanal electrode insertion technique is a safe and effective surgical approach for cochlear implantation in patients with sensorineural deafness. This method ensures successful electrode placement and good implant function with no major complications.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Biomedical Engineering

Background:

  • Sensorineural deafness impacts millions globally, necessitating advanced auditory restoration solutions.
  • Cochlear implantation is a proven treatment, but surgical techniques continue to evolve for improved outcomes.

Purpose of the Study:

  • To evaluate the safety and efficacy of the pericanal electrode insertion technique for cochlear implantation.
  • To assess the feasibility of this surgical approach in a clinical setting.

Main Methods:

  • Forty patients with sensorineural deafness underwent cochlear implantation using the pericanal technique.
  • Cochleostomy was performed anterior to the round window via the external auditory canal.
  • Intraoperative electrode impedance and electrically auditory brainstem responses (EABR) were monitored; postoperative X-rays were taken.

Main Results:

  • Successful electrode insertion was achieved in all 40 cases.
  • All cochlear implants functioned well post-surgery.
  • No electrode extrusions or significant surgical complications were observed during a 6-month follow-up period.

Conclusions:

  • The pericanal electrode insertion technique represents a safe and reliable surgical method for cochlear implantation.
  • This approach facilitates successful electrode placement and demonstrates a low complication rate.
