Summary

Surgical residents found physical temporal bone models more realistic than virtual models for training. Both simulation types are effective, but physical models were preferred for their tactile properties and anatomical accuracy.

Area of Science:

  • Medical Simulation
  • Surgical Education
  • Otolaryngology Training

Background:

  • Simulation is crucial in surgical education.
  • Comparing different simulation modalities is essential for optimizing training.
  • Temporal bone dissection is a key skill in otolaryngology.

Purpose of the Study:

  • To directly compare resident perceptions of physical (PBM) and virtual (VM) temporal bone simulation models.
  • To evaluate the effectiveness and realism of each simulation modality for surgical training.

Main Methods:

  • A prospective cohort study involving ten otolaryngology residents.
  • Development of a haptic voxel-based virtual model (VM) and a physical 3D-printed temporal bone model (PBM).
  • Residents rated and compared simulations using Likert scales and rank lists based on micro-CT data.

Main Results:

  • Physical models (PBM) were rated significantly more similar to cadaveric bone for drill quality and air cell representation.
  • Both PBM and VM were considered effective educational tools, with PBM rated higher.
  • Residents preferred PBM in 7 out of 9 educational domains, citing more realistic physical properties.

Conclusions:

  • Both physical and virtual temporal bone models offer educational benefits.
  • Physical 3D-printed models were perceived as more realistic and were the preferred training instrument.
  • Integration of both modalities into otolaryngology training is recommended, with a preference for physical models.
