Proceedings of SPIE--the International Society for Optical Engineering·2015

Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Neurosurgery

Background:

  • Cochlear implant electrode design aims to improve hearing restoration.
  • Minimizing insertional trauma is crucial for preserving residual hearing.

Purpose of the Study:

  • Evaluate insertional properties of new Advanced Bionics cochlear implant electrode arrays.
  • Assess the Thin Lateral and Helix II arrays for atraumatic insertion.

Main Methods:

  • Human cadaveric temporal bone dissection.
  • Insertion of Thin Lateral and Helix II electrode arrays.
  • Assessment of electrode position, depth, and intracochlear trauma.

Main Results:

  • Mean insertion depths: 368° (Thin Lateral) and 436° (Helix II).
  • No insertional trauma observed with either electrode type.
  • Favorable insertion characteristics confirmed via direct observation.

Conclusions:

  • Both Thin Lateral and Helix II electrodes demonstrate favorable performance.
  • These arrays show promise for clinical application, particularly for preserving residual hearing.
