Summary
Particulate cancellous bone and marrow (PCM) grafts achieved an 88% success rate for mandible reconstruction. Dynamic bendable defect bridging plates with cancellous cortical grafts also successfully rehabilitated all patients, showing promise for complex defects.
Area of Science:
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
- Biomaterials in Medicine
Background:
- Mandibular defects pose significant reconstructive challenges.
- Various surgical techniques exist for mandibular reconstruction, each with unique indications and outcomes.
Purpose of the Study:
- To evaluate the efficacy of different reconstructive techniques for mandibular defects.
- To compare the success rates of particulate cancellous bone and marrow (PCM) grafts versus dynamic bendable defect bridging plates with cancellous cortical grafts (DBDB plate with CCG).
Main Methods:
- Retrospective analysis of 45 patients undergoing mandibular reconstruction.
- Application of particulate cancellous bone and marrow (PCM) crib grafts in 34 patients.
- Utilization of dynamic bendable defect bridging plate with cancellous cortical graft (DBDB plate with CCG) in 7 patients.
- Assessment of reconstructive success based on primary operation outcomes and secondary rehabilitation.
Main Results:
- Particulate cancellous bone and marrow (PCM) crib grafts demonstrated an 88% success rate in the primary operation (30 out of 34 patients).
- All 7 patients treated with the DBDB plate with CCG were successfully rehabilitated, achieving a stable mandibular arch.
- Osteomyocutaneous flaps were effective in restoring function and form for tumor patients.
Conclusions:
- Particulate cancellous bone and marrow (PCM) grafts are a reliable first-line approach for mandibular non-union.
- The DBDB plate with CCG is increasingly relied upon for large bony defects resulting from trauma or tumor surgery.
- Osteomyocutaneous flaps are highly successful for anterior mandibular reconstruction in oncologic cases.
