Area of Science:

  • Medical Imaging
  • Computer-Aided Surgery
  • Artificial Intelligence

Background:

  • Maxillofacial surgery planning often requires patient-specific implants.
  • Current methods for implant design can be time-consuming and complex.
  • Existing shape completion networks primarily address neurocranial defects.

Purpose of the Study:

  • To evaluate shape completion neural networks for reconstructing 3D meshes of maxillofacial defects.
  • To develop a pipeline for automatic 3D mesh reconstruction from CT data for surgical planning.
  • To address defects in both the neurocranium and splanchnocranium.

Main Methods:

  • A novel dataset of CT scans with pre-processed point clouds and virtual defects was created.
  • State-of-the-art point cloud completion networks were compared.
  • The most effective network was evaluated by expert surgeons on a clinical case.

Main Results:

  • Two promising shape completion networks were identified for reconstructing 3D meshes.
  • The best-performing network demonstrated potential in a clinical evaluation.
  • The study successfully adapted shape completion for complex maxillofacial defects.

Conclusions:

  • Shape completion networks offer a promising avenue for automating personalized implant design in maxillofacial surgery.
  • This approach can streamline the surgical planning process for complex craniofacial reconstructions.
  • Further development could significantly enhance clinical decision-making and patient outcomes.
