Summary
Free vascularized radius bone grafts offer a viable alternative for mandibular reconstruction, enabling successful osseointegrated implant placement. This technique improves oral function and aesthetics after oromandibular resection.
Area of Science:
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
- Biomaterials Engineering
Background:
- Oromandibular resection presents significant challenges for oral rehabilitation, including impaired speech, mastication, and aesthetics.
- Osseointegrated implants and free vascularized bone grafting have improved reconstructive outcomes.
- The iliac crest is a common graft source, but alternatives are explored for specific defect types.
Observation:
- This study reports on four cases of mandibular reconstruction utilizing free vascularized radius grafts.
- Osseointegrated implants were subsequently placed in the reconstructed mandible.
- The radius graft was employed for small to moderate lateral mandibular defects involving oral mucosa loss.
Findings:
- The free vascularized radius graft proved successful in reconstructing mandibular defects.
- Enosseous implants were successfully placed and integrated within the radius graft.
- The radius graft provided a stable foundation for prosthetic rehabilitation.
Implications:
- The radius is a suitable alternative for mandibular reconstruction, particularly for lateral defects.
- Combined free vascularized radius grafting and osseointegrated implants enhance functional and cosmetic restoration.
- This approach offers improved oral continence, denture stability, and reduced deformity.
