This study introduces a 3D virtual dissection training system for endoscopic endonasal approaches. The system enhances surgical skills, anatomical knowledge, and preoperative planning for skull base procedures.

Area of Science:

  • Neurosurgery
  • Anatomy
  • Medical Education

Background:

  • Endoscopic endonasal approaches are complex procedures requiring specialized training.
  • Traditional dissection methods may not fully replicate the nuances of virtual surgical environments.

Purpose of the Study:

  • To describe a novel 3D virtual dissection training system for endoscopic endonasal approaches.
  • To evaluate its efficacy in improving surgical skills and anatomical understanding.

Main Methods:

  • Utilized a multi-stage protocol involving virtual dissection, 3D model-based exploration, cadaveric dissection with neuronavigation, and data analysis.
  • Employed human cadaveric heads at the Laboratory of Surgical Neuro-Anatomy.

Main Results:

Published on: November 19, 2017

  • The integrated system effectively trained manual dexterity and hand-eye coordination.
  • Improved general knowledge of surgical approaches and anatomical landmarks was observed.

Conclusions:

  • The 3D virtual dissection model is effective for surgical anatomy representation and provides valuable 3D visual feedback.
  • The system serves as a powerful tool for preoperative planning and practicing complex skull base approaches.
