Reconstruction of the Mandible Bone by Treatment of Resected Bone With Pasteurization

The results of long-term follow-up for reimplantation of the mandibular bone treated with pasteurization are reported. Mandibulectomy was performed for mandibular malignancy in 3 cases. The resected bones were subsequently reimplanted after treatment with pasteurization in 3 cases to eradicate tumor cells involved in the resected bone. Although postoperative infection was observed in 2 of 3 cases, reimplantation of the resected mandibular bone treated by pasteurization was finally successful. Ten to 22 years of follow-up was carried out. Pasteurization was able to devitalize tumor cells involved in the resected bone and to preserve bone-inductive activity. Reimplantation of pasteurization could be a useful strategy for reconstruction of the mandible in patients with mandibular malignancy.
