Summary
This study aims to create a database of 3D CT scans to compare patients with craniofacial defects to average anatomy. This will aid in planning surgical interventions for improved patient outcomes.
Area of Science:
- Medical Imaging
- Computer-Aided Surgery
- Craniofacial Surgery
Background:
- Achieving ideal patient appearance in craniofacial surgery is crucial.
- Reconstruction aims to restore the patient's natural appearance, free from defects.
- A reference standard for normal craniofacial anatomy is needed for comparison.
Purpose of the Study:
- To establish a database of 3D computed tomography (CT) images.
- To create age- and sex-matched "average" anatomical models for comparison.
- To facilitate the planning of craniofacial surgical interventions.
Main Methods:
- Collection of 3D CT data from patients without pathologies.
- Collaboration with radiology institutes in Mannheim and Heidelberg.
- Classification of over 100 CT datasets by age and sex.
- Selection of appropriate statistical methods for norm data calculation.
Main Results:
- A database of over 100 3D CT datasets has been collected and classified.
- The foundation for creating age- and sex-matched average anatomical models is established.
- Methodology for statistical norm data calculation is being determined.
Conclusions:
- The developed CT image database is a critical first step towards personalized craniofacial surgery.
- The creation of average anatomical models will enhance surgical planning and outcomes.
- This approach supports the goal of achieving near-natural patient appearance post-intervention.
