This study presents a craniofacial surgery planning system using 3D models from tomographic images. It enables accurate simulation of surgical actions for complex procedures like Frontal Orbital Advancement (FOA).

Area of Science:

  • Medical Imaging
  • Surgical Planning
  • Computer-Aided Surgery

Background:

  • Craniofacial surgery relies on tomographic image-slices for pre-operative planning.
  • Reconstructing 3D geometric models from these slices aids visualization but lacks simulation capabilities for complex interventions.

Purpose of the Study:

  • To develop a comprehensive operation planning system for craniofacial surgery.
  • To integrate geometrical and haptical models with interaction methods for accurate and intuitive surgical simulation.

Main Methods:

  • Reconstruction of 3D geometric and haptical models from tomographic image-slices.
  • Development of simulation methods for surgical activities (drilling, milling, deforming, positioning).
  • Integration of interaction methods for intuitive planning.

Main Results:

  • The developed system generates precise anatomical models from image-slices.
  • It allows for the simulation of complex surgical actions, including cutting trajectories and bone manipulation.
  • The system provides physicians with tools for accurate and intuitive surgical planning.

Conclusions:

  • The developed operation planning system enhances craniofacial surgery planning by combining 3D modeling with advanced simulation.
  • The system is already in clinical use, demonstrating its practical applicability and effectiveness in Heidelberg.
