Autologous double barrel vascularized fibular bone graft for reconstruction after hemi resection of mandible due to ameloblastoma: Surgical case report

INTRODUCTION: Mandibular abnormalities caused by ameloblastoma present significant surgical and reconstructive difficulties. This study investigates double barrel fibular bone graft to correct these abnormalities and improve mandibular function and appearance. CASE PRESENTATION: A 28-year-old male presented with a mandibular lump and facial asymmetry. The radiographic and histologic examination detected was subsequently diagnosed as ameloblastoma. After undergoing a hemi mandibulectomy procedure, a free vascularized fibular bone graft was harvested from the patient's left leg and transplanted to reconstruct the mandibular angle. The evaluation of the patient's functional outcomes was assessed utilising the University of Washington Quality of Life (UW-QOL) questionnaire. The patient UW – QOL Score has increased 62.5 pre-treatment to 93.75 post-treatment. DISCUSSION: The suggested strategy to treating aggressive ameloblastomas is radical surgery, involving the use of wide resection and following bone reconstruction. Vascularized grafts, including the double-barrel fibular bone graft, are usually preferred in relation to mandibular defect reconstruction for their ability to offer improved stability, height, and thickness, which enhances functional results. In contrast to conventional approaches, our case did not show any signs of facial deformities or bone resorption. The utilization of the vascularized fibular bone graft proved to be a valuable option for early rehabilitation in patients with mandibular continuity defects, offering promising outcomes in terms of patient well-being and quality of life. This final result provides proof supporting the potential of this technique for managing mandibular defects. CONCLUSION: Double-barrel fibular bone grafts and dental rehabilitation can restore mandibular continuity defect from ameloblastoma.
