Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Pediatric Endoscopy

Background:

  • Acquiring proficiency in neuroendoscopic procedures demands extensive training.
  • Current training methods may not adequately prepare surgeons for complex operations.
  • A need exists for realistic simulation tools in pediatric neurosurgery.

Purpose of the Study:

  • To introduce a new pediatric neuroendoscopic simulator designed to facilitate surgical training.
  • To provide a realistic and safe platform for practicing essential neuroendoscopic techniques.
  • To evaluate the simulator's potential in improving surgical skills and reducing the learning curve.

Main Methods:

  • Development of a simulator using Neoderma®, a synthetic thermo-retractile and thermo-sensible rubber, combined with polymers for realistic tissue properties.
  • Construction of a basic module using silicon and fiberglass molds replicating pediatric cerebral ventricles.
  • Incorporation of functionalities for practicing ventricular navigation, third ventriculostomy, choroid plexus cauterization, and tumor resection with simulated bleeding.

Main Results:

  • The simulator accurately replicates the textures, consistencies, and mechanical resistances of human tissues.
  • It enables practice of fundamental neuroendoscopic techniques, including navigation of key anatomical landmarks.
  • Both rigid and flexible endoscopy can be performed with high fidelity to real surgical scenarios.

Conclusions:

  • The developed pediatric neuroendoscopic simulator offers a realistic and risk-free training environment.
  • It has the potential to significantly improve the learning curve for inexperienced neurosurgeons.
  • The simulator can aid in the dissemination of advanced techniques like flexible endoscopy.
