A new artificial temporal bone (TB) model offers a viable training tool for cochlear implantation surgery. While not a complete replacement for cadaveric specimens, this model aids in developing surgical skills.

Area of Science:

  • Otolaryngology
  • Surgical Simulation
  • Biomedical Engineering

Background:

  • Cochlear implantation requires extensive surgical training.
  • Cadaveric temporal bones (TB) are valuable but limited resources for training.

Purpose of the Study:

  • To describe and evaluate a novel artificial temporal bone (TB) model for cochlear implantation surgical training.

Main Methods:

  • An artificial TB model was developed using micro-computed tomographic images, mimicking bone material properties and anatomical details.
  • Eight experienced otologists compared the artificial TB model with human cadaveric TBs using a questionnaire and macroscopic/microscopic assessments.
  • Surgical steps including mastoidectomy, posterior tympanotomy, cochleostomy, and electrode insertion were evaluated.

Main Results:

  • The artificial TB model demonstrated comparable material properties and anatomical details to human cadaveric TBs.
  • Surgical procedures, including electrode insertion, were rated as comparable between the artificial model and cadaveric specimens.
  • The round window membrane was identified as an area needing improvement in the model.

Conclusions:

  • The developed artificial TB model is suitable for surgical training in cochlear implantation.
  • This model serves as an accessible alternative for honing surgical skills, though it does not fully replace cadaveric TBs.
  • Expanding the range of artificial TB models (e.g., infant or malformed) would enhance their training utility.
