Summary
This study presents a novel technique for mandibular reconstruction using living bone from the skull. The method ensures excellent shape, vascularization, and successful functional and cosmetic restoration for patients with mandibular defects.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Biomedical Engineering
Background:
- Mandibular defects require reconstruction to restore facial function and aesthetics.
- Reconstruction necessitates living bone of suitable quality and shape to withstand masticatory stress and resist infection.
Purpose of the Study:
- To report a technique for mandibular reconstruction using full-thickness calvarial bone.
- To evaluate the criteria, vascularization, and success rates of this specific reconstruction method.
Main Methods:
- Utilizing a pedicled galeal flap (superficial temporal artery) for vascularization of the calvarial bone graft.
- Reconstructing mandibular defects with full-thickness bone grafts suitable for dental implants.
- Analyzing patient cases based on defined reconstruction criteria.
Main Results:
- The calvarial bone flap demonstrated good shape and reliable vascularization.
- The technique achieved a high success rate in both functional and cosmetic outcomes.
- The living bone graft effectively resisted infection and masticatory stress.
Conclusions:
- This pedicled calvarial bone flap technique is a reliable method for mandibular reconstruction.
- The approach offers excellent cosmetic and functional results, suitable for implant placement.
- The study highlights the importance of vascularized bone grafts in complex reconstructive surgery.
