This study demonstrates that cost-effective 3D-printed temporal bone models can be manufactured in-house for mastoidectomy training. These models offer a viable alternative to cadaveric dissection for surgical education.

Area of Science:

  • Biomedical Engineering
  • Medical Education Technology

Background:

  • 3D-printed temporal bone models offer a cost-effective, locally manufacturable alternative to cadaveric surgery for training.
  • Current training methods can be limited by the availability and cost of cadavers.

Purpose of the Study:

  • To develop a cost-effective 3D-printed temporal bone model for mastoidectomy training.
  • To enable individuals with no prior 3D-printing experience to create their own training models.

Main Methods:

  • Utilized entry-level 3D-printing technology and heat-resistant filament for model creation.
  • Incorporated post-processing steps to replicate key anatomical structures like the dura, sigmoid sinus, and facial nerve.
  • Modified 3D-printers with direct-drive extruders and ruby nozzles for improved print quality and reduced maintenance.

Main Results:

  • The 3D-printed model effectively replicated temporal bone anatomy for mastoidectomy training.
  • Otorhinolaryngology trainees reported the model provided a good introduction to the procedure.
  • The models supplemented cadaveric temporal bone practice.

Conclusions:

  • In-house production of 3D-printed temporal bone models for surgical training is feasible.
  • This approach empowers training institutions to produce their own cost-effective models.
  • The methodology allows for the creation of models with anatomical variations for diverse training scenarios.
