Summary

Deep insertion of Combi-40 cochlear implant electrodes into the apical scala tympani caused minimal trauma. Avoiding force when resistance is met prevents severe damage like electrode kinking or membrane rupture.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Biomedical Engineering

Background:

  • Cochlear implant electrode insertion into the apical cochlea is complex.
  • Understanding insertional trauma is crucial for auditory function preservation.

Purpose of the Study:

  • To evaluate insertional trauma from deep Combi-40 cochlear implant electrode insertions.
  • To identify factors contributing to cochlear damage during implantation.

Main Methods:

  • 12 human temporal bones underwent deep insertion of Combi-40 electrodes.
  • Histological processing with implants in situ using sawing and grinding techniques.

Main Results:

  • Most cases showed minimal epithelial distortion in the spiral ligament.

  • Occasional slight basilar membrane displacement was observed.
  • Severe damage (membrane rupture, electrode displacement, osseous spiral lamina fracture) occurred when excessive force was applied beyond resistance points.

    • Conclusions:

    • Deep electrode insertion is feasible with minimal trauma under specific conditions.
    • Applying force when resistance is encountered significantly increases the risk of severe cochlear damage.
