ABSTRACT:Background: Distraction osteogenesis (DO) has emerged as a transformative technique in maxillofacial reconstruction, offering a biologically driven method for bone lengthening and repair of severe defects. Traditional methods often involve grafting, which may present challenges such as limited donor sites and graft rejection. DO has provided a reliable alternative, promoting natural bone regeneration and minimizing the need for extensive grafting. Aim: The study aimed to evaluate the role of distraction osteogenesis in maxillofacial reconstruction, specifically its efficacy and safety in bone lengthening and the repair of severe maxillofacial defects. Methods: This retrospective study was conducted from June 2023 to June 2024, involving 50 patients with severe maxillofacial defects treated using distraction osteogenesis. Clinical data, including pre- and post-operative radiographs, surgical outcomes, and patient-reported satisfaction, were analyzed. Key metrics assessed included bone regeneration rates, complication incidence, and aesthetic and functional outcomes. Results: The study demonstrated that distraction osteogenesis effectively addressed severe maxillofacial defects, achieving a mean bone lengthening of 12.5 ± 2.3 mm. The success rate was 92%, with minimal complications, including minor infections (8%) and device-related issues (6%). Conclusion: Distraction osteogenesis proved to be a safe and effective modality for maxillofacial reconstruction, offering significant improvements in bone lengthening, defect repair, and patient satisfaction. Its ability to facilitate natural bone regeneration makes it a valuable alternative to traditional methods. Future studies could explore advanced technologies to further optimize outcomes and reduce complications.
