A New Regenerative Approach to Oromandibular Reconstruction After the Resection of Head and Neck Malignant Tumor

Abstract

We developed a new regenerative oromandibular reconstruction technique. In our technique, bone marrow was removed from surgically resected mandible, and then the mandible was heat-treated and prepared into a cortical bone tray. This tray was fixed on the defect area, iliac cancellous bone was grafted into its lumen, the entire circumference was covered with the muscle part of pectoral major myocutaneous flap, and the oral defect and the skin defect on the lower jaw were reconstructed with the skin paddles of the skin island of the flap. Two patients were treated with this technique after the removal of oral cavity cancer. The patients did not develop postoperative complications, the reconstructed mandible as well as the flap were completely taken, and normal shape of the mandible was regained. This technique would be one of the useful oromandibular reconstruction methods.
