3-D reconstructed solid models of neurosurgical pathologies aid surgical planning. Solidified photopolymer models visualize cranial vessels, while milled urethane models detail intracranial pathologies and skull base anatomy for improved simulation.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Solid models aid in understanding complex neurosurgical pathologies.
  • Preoperative simulation is crucial for successful neurosurgical interventions.

Purpose of the Study:

  • To present and examine two types of 3-D reconstructed solid models for neurosurgical pathologies.
  • To appraise the clinical usefulness of these models through neurosurgical simulation.

Main Methods:

  • Solidifying liquid photopolymer based on 3-D MR angiography data for cranial vessel models.
  • Milling urethane block based on CT data for intracranial pathologies and skull base anatomy models.

Main Results:

  • Photopolymer models offered visual and tactile perception, aiding aneurysm origin visualization and preoperative planning for transarterial embolization.

  • Milled urethane models effectively demonstrated middle fossa lesions and anatomical relationships, facilitating surgical approach decisions.
  • Both methods proved advantageous for visualizing complex or minute structures and anatomical details.

    • Conclusions:

    • 3-D reconstructed solid models, utilizing photopolymer or milled urethane, are valuable tools for neurosurgical simulation and preoperative planning.
    • These models enhance understanding of complex anatomy and pathologies, improving surgical strategy and potentially patient outcomes.
