Area of Science:

  • Medical Education
  • Anatomical Modeling
  • Surgical Anatomy

Background:

  • Learning hepatic segment anatomy presents challenges for medical students.
  • Traditional anatomical atlases lack the depth for effective spatial understanding.
  • Three-dimensional visualization (3DV) aids anatomy teaching but lacks tactile feedback.

Purpose of the Study:

  • To develop a novel three-dimensional printing (3DP) model of hepatic segments.
  • To compare the educational effectiveness of 3DP models, 3DV models, and traditional anatomical atlases.

Main Methods:

  • A 3D model of hepatic structures was created from CT scans.
  • The model was adapted for both 3DV and 3DP hepatic segment representations.
  • A randomized controlled trial evaluated the teaching effectiveness against anatomical atlases.

Main Results:

  • Both 3DV and 3DP models demonstrated superior teaching effectiveness over traditional atlases.
  • Experts rated the realism of 3D models highly, with no significant difference between 3DV and 3DP.
  • Students using 3D models showed better retention, unlike those using traditional methods.

Conclusions:

  • A novel 3DP hepatic segment model was successfully developed.
  • Both 3DV and 3DP models significantly enhance the teaching of hepatic anatomy.
  • 3D modeling offers a more effective and engaging approach to anatomical education.
