Abstract: Objective To explore the effect of stage-I reconstruction with nonvascularized rib grafts or iliac grafts post mandibular segmental resection. Methods The analysis was based on the 16 patients admitted in our hospital from 2004 to 2012. They developed with severe mandiblular defects resulting from benign tumors and mandibular segmental resection and were chosen to undertake stage-I reconstruction with autologous nonvascularized rib grafts or iliac grafts. Results Incisions of all cases recovered in phase I. During the follow-up period of 1 to 12 months, one case of fistula and one case of graft necrosis were observed in all cases. All grafted bones survived with satisfied occlusions and appearances. The effects of the cases with half mandible defects were also accepted with appearance repair and basic occlusive function. Conclusion Satisfactory effect can be achieved by applying nonvascularized rib or iliac grafts to stage-I postoperative reconstruction post mandibular segmental resection. The operative procedure is relatively simple and no vascular anastomosis technique is needed. Taken together, it makes nonvascularized rib or iliac grafts to be an applicable method of mandibular defect repairing.
