    Abstract:
    Over the past 15 years, reconstruction following excision of malignant oral tumors was performed on 27 patients with segmental resection and five patients with hemiresection of the mandible. Following segmental resection, the mandible was reconstructed using an autogenous bone graft in eight patients in whom the surrounding soft tissues were fairly well preserved. Bony union was achieved in six of them. In the remaining two, the graft was removed because of postoperative infection, and one patient underwent secondary bone grafting. A pedicled myocutaneous flap and bone graft was used in seven patients who underwent extensive resection of the surrounding soft tissue. Bony union was achieved in three patients, and one developed pseudoarthrosis. The graft was removed in the remaining three because of postoperative infection. Reconstruction with only a metallic plate for stabilization of the mandible was carried out in six aged or sarcoma-affected patients. In two of them, the postoperative course was uneventful for 4 to 7 years. In the remaining four patients, plate removal was required because of exposure or tumor recurrence. In 5 of 11 patients in whom reconstruction was carried out with a combination of a pedicled myocutaneous flap and metallic plate, the postoperative course was uneventful for 2 to 8 years. Two of these five patients underwent secondary bone grafting. In four of the remaining six patients, the plate was removed because of exposure or improper adaptation to the stump. Two others died of disseminated intravascular coagulation syndrome within 1 month. A prosthesis was used more frequently by patients when reconstruction was performed using a pedicled osteomyocutaneous flap. The metallic reconstruction plate was helpful for restoring mandibular contour.(ABSTRACT TRUNCATED AT 250 WORDS)
