A new synthetic model effectively simulates foramen ovale puncture for trigeminal neuralgia treatment training. This tool aids neurosurgeons in practicing this critical percutaneous procedure, especially where cadavers are scarce.

Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Anatomical Modeling

Background:

  • Trigeminal neuralgia (TN) is a prevalent cause of facial pain.
  • Percutaneous procedures targeting the Gasserian ganglion via foramen ovale puncture are alternatives when conservative treatments and microdecompression fail.
  • This procedure requires specialized neurosurgical expertise.

Purpose of the Study:

  • To develop and evaluate a novel training model for foramen ovale puncture.
  • To provide a safe and accessible practice tool for neurosurgical residents and young neurosurgeons.

Main Methods:

  • A skull base model was constructed using synthetic materials to replicate the human face.
  • The model was designed to simulate the anatomy encountered during foramen ovale puncture.

Main Results:

  • The synthetic model demonstrated high fidelity, closely resembling anatomical structures during conventional surgeries.
  • Repeated testing by experienced neurosurgeons and residents confirmed the model's realism and utility.

Conclusions:

  • The developed foramen ovale puncture model is a valuable training aid for foundational practice of this neurosurgical intervention.
  • This simulation is particularly beneficial in training settings with limited access to cadaveric specimens.
