抄録
Facial swelling is a postoperative reaction of mandibular osteotomy. Several methods of evaluating facial swelling have been reported, but they are technically complicated. In this study, we examined the factors contributing to postoperative facial swelling and its quantitative assessment using the postero-anterior cephalogram.<BR>The subjects were 40 patients who underwent mandibular osteotomy.<BR>A preliminary study of various parameters on cephalograms taken at three time points: immediately after, 3 months after, and 6 months after, surgery, showed that the width of the soft tissue on the occlusal plane line was most useful in evaluating postoperative swelling, because it decreased most significantly at 3 months, as compared to immediately after surgery, and it remained unchanged at 6 months.<BR>When the swelling index was defined as the ratio of the width immediately after surgery to that at 3 months, there were significant correlation among the index, the amount of hemorrhage and the number of segmental leukocytes. The index for sagittal split ramus osteotomy was also different from that for intraoral vertical ramus osteotomy.<BR>In conclusion, the swelling index, calculated from the frontal cephalometric radiograph, is effective for quantitative assessment of facial swelling.
