Volumetric fibular transfer planning with shape-based indicators in mandibular reconstruction
Summary
This study introduces new simulation software for mandibular reconstructive surgery. The system optimizes fibular segment placement using direct volume manipulation and quantitative analysis, improving surgical planning.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Medical Imaging
Background:
- Preoperative planning for mandibular reconstruction requires precise osteotomy and segment placement.
- Current virtual surgical planning software often involves manual, iterative refinement.
Purpose of the Study:
- To develop and evaluate novel volumetric fibular transfer simulation software for mandibular reconstruction.
- To enhance preoperative planning efficiency and accuracy through direct volume manipulation and quantitative comparison.
Main Methods:
- Developed simulation software with direct volume manipulation and quantitative shape indicators (volume ratio, contour error, maximum projection).
- Implemented a parallel computation algorithm for semi-automatic fibular segment placement.
- Conducted a retrospective study using computed tomography data from nine patients.
Main Results:
- The developed software enables quick preoperative plan design.
- Combining direct volume manipulation with real-time local search improved planning system applicability.
- Quantitative indicators facilitate optimized mandibular reconstruction.
Conclusions:
- The volumetric fibular transfer simulation software offers a more efficient and accurate approach to mandibular reconstruction planning.
- This technology has the potential to optimize surgical outcomes in complex cases.
