Summary
Computer-assisted surgery significantly improves mandibular reconstruction outcomes. This method enhances graft fit, reduces surgical time, and leads to greater patient satisfaction with esthetic results.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Mandibular reconstructive surgery aims to restore function (mastication, speech) and aesthetics.
- Vascularized iliac crest bone grafts are commonly used for mandibular reconstruction.
Purpose of the Study:
- To compare computer-assisted (CA) with conventional mandibular reconstruction techniques.
- To evaluate functional and esthetic outcomes of CA mandibular reconstruction.
Main Methods:
- Comparison of 5 CA reconstructions with 15 conventional reconstructions using vascularized iliac crest bone grafts.
- Preoperative imaging (CBCT/CT) guided virtual surgical planning and rapid prototyped surgical guides.
- Intraoperative measurement of graft ischemic time and bone volume assessment.
- Postoperative patient-reported esthetic outcome scoring using a visual analog scale at 3 months.
Main Results:
- Perfect graft fit in all patients, minimizing intraoperative adjustments.
- Shorter graft shaping time and reduced ischemic time in the CA group.
- Virtual planning optimized bone harvesting, reducing excess bone removal.
- Patients in the CA group reported higher satisfaction with their outer appearance.
Conclusions:
- Computer-assisted mandibular reconstruction using iliac crest bone grafts is a promising method.
- This technique optimizes surgical results, achieving excellent functional and esthetic outcomes.
- The described CA approach enhances patient satisfaction in mandibular reconstruction.
