Summary
Computer-aided design and stereomodels enabled accurate mandibular reconstruction using vascularized iliac crest flaps. Patients reported excellent satisfaction with facial appearance and function post-surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Mandibular defects pose significant reconstructive challenges.
- Vascularized iliac crest flaps are a common method for mandibular reconstruction.
- Preoperative planning is crucial for optimal outcomes.
Purpose of the Study:
- To evaluate the accuracy and outcomes of mandibular reconstruction using computer simulation and stereomodels with vascularized iliac crest flaps.
- To compare actual surgical results with preoperative computer-generated plans.
Main Methods:
- Fourteen patients underwent mandibular reconstruction using vascularized iliac crest flaps.
- Computer simulation was used to superimpose iliac crests onto mandibular defects for optimal donor site selection.
- Stereomodels were utilized to replicate the preoperative surgical plan during the operation.
Main Results:
- Successful bony union and good occlusion were achieved in all 14 patients.
- Actual surgical outcomes closely matched the computer-generated simulations.
- All patients reported excellent or good facial appearance at 1-year follow-up.
Conclusions:
- Computer simulation and stereomodel-assisted planning enhance the accuracy of mandibular reconstruction with vascularized iliac crest flaps.
- This technique facilitates the achievement of ideal neomandibular contour and function.
- High patient satisfaction with facial appearance and function is achievable.
