Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Surgical Education

Background:

  • Stereotactic techniques are crucial in neurosurgery.
  • Simulation training offers a safe environment to improve technical skills.
  • A need exists for accessible, low-cost simulation models.

Purpose of the Study:

  • To describe a novel, combined cadaveric and synthetic low-cost stereotactic simulation model.
  • To validate the model's efficacy through neurosurgeon assessment.

Main Methods:

  • A brain model was created using self-supporting gel with simulated lesions.
  • Imaging scans were used for target coordinate calculation.
  • Standard frame needle biopsies were performed to assess performance.

Main Results:

  • Median mistakes decreased from 32 to 3.5 (P < 0.001) after training.
  • Median task completion time reduced from 1020.5 to 479 seconds (P < 0.0001).
  • The model provided immediate haptic feedback.

Conclusions:

  • A handmade, low-cost stereotactic simulation model was developed.
  • The model effectively enhances neurosurgical trainees' stereotactic skills.
  • This simulation tool reduces errors and time, improving surgical training.
