Summary
Preoperative virtual planning for mandible reconstruction using virtual surgery and CAD/CAM techniques significantly improved surgical accuracy and patient outcomes, focusing on esthetics and occlusion.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- 3D Medical Imaging
Background:
- Mandible reconstruction presents challenges in achieving optimal esthetics and functional occlusion.
- Virtual surgical planning offers a potential solution for complex reconstructive procedures.
Observation:
- A prospective study involved 9 patients undergoing mandibulectomy and simultaneous fibula reconstruction.
- Preoperative CT scans were utilized for virtual surgical planning and fabrication of surgical templates.
Findings:
- Virtual planning enabled accurate surgical execution, with all fibula flaps surviving.
- Patients reported satisfactory aesthetic results and improved occlusal relationships post-reconstruction.
Implications:
- Preoperative virtual planning enhances the precision of mandible reconstruction, leading to superior functional and esthetic outcomes.
- This approach allows for individualized planning of the mandible and fibula graft spatial relationship.
