[Free nonvascularized bone graft evolution after mandibular resections: 45 cases report]

The resection of mandibular benign tumors often require reconstruction. The purpose of our study is to present the middle and long-term results of 45 patients, treated by free no-vascularized bone graft after resection of benign tumors, dominated by the ameloblastoma. The PSIM type III hemimandibulectomy was the most frequent (58%). A combined approach was necessary in the majority of cases. The immediate reconstruction by corticospongeal iliac grafts fixed by screws plaques with intermaxillary blockage was the most used technique (95%). The mean follow was 4.5 years. The evolution was marked by good osteointegration of the graft, with good functional and morphologic results in 40%. The infection and bone resorption represented the major complications and were interrelated, so the infection was noted in 9 cases. The bone resorption hampered the evolution with a bad functional and morphological result in 4 cases (9%).
