Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Biomedical Engineering

Background:

  • Magnet displacement is a rare but serious complication after cochlear implant surgery.
  • This complication requires revision surgery, increasing patient risk and morbidity.

Observation:

  • A 5-year-old patient experienced magnet displacement twice.
  • A novel surgical technique, the "lasso" technique, was developed to re-secure the internal magnet.

Findings:

  • The lasso technique successfully re-secured the dislodged magnet in the described case.
  • The patient's cochlear implant remained functional with a stable magnet 36 months post-surgery.

Implications:

  • The lasso technique offers a simple, safe, and cost-effective alternative to other surgical methods for magnet displacement.
