This study introduces a 3D-printed physical model for endoscopic endonasal approach (EEA) skull base surgery training. The simulator offers realistic haptic feedback and bony landmarks, aiding surgeons in mastering complex drilling techniques.

Area of Science:

  • Neurosurgery
  • Medical Simulation
  • 3D Printing Applications

Background:

  • Endoscopic endonasal approach (EEA) is vital for skull base pathologies.
  • Endonasal drilling demands specialized skills due to unique instruments and restricted access.
  • Surgical competency requires extensive practice with specialized training tools.

Purpose of the Study:

  • To develop and validate a novel 3D-printed physical model for surgical training in EEA.
  • To assess the content validity and haptic realism of the developed simulator.

Main Methods:

  • Utilized 3D printing technology to create a physical training model from CT scans.
  • Formulated materials for realistic haptic feedback and endoscope handling.
  • Conducted a preliminary assessment at two institutions to evaluate content validity.

Main Results:

  • The 3D-printed EEA simulator demonstrated positive content validity.
  • Participants reported high satisfaction with the realism of bony landmarks and haptic response.
  • Minor refinements were suggested for optimization as a training device.

Conclusions:

  • The developed 3D-printed model shows promise as an effective tool for endoscopic endonasal approach surgical training.
  • The simulator provides a realistic platform for practicing critical drilling techniques.
  • Further validation is recommended before widespread clinical implementation.
