• 論文抄録 / 内容記述: Jaw deformity is a growth and developmental disorder that indicates malocclusion accompanied by deformity of the upper and lower jaw, which both oral and maxillofacial surgery concern. Planning and evaluation of orthognathic surgery have based on hard tissue such as jaw bones and teeth, because they were suitable for incorporating tomographic imaging technologies. But the changes in the soft tissues that cover the repositioned jaw bones and teeth vary among individuals and have been left to the empirical decisions of the surgeons. Possible problems in the facial appearance after surgery, however, throw even greater negative impact on the patients' quality of life. Soft tissues need more accurate treatment to be considered. Silhouettes of patients' profile faces used for evaluating soft tissues in the past do not necessarily show cheek bulges that are critical to considering the factor of personality. This research proposes a computer-assisted image analysis method that is capable of quantitatively measuring the effect of orthognathic surgery over soft tissues. It reads a cephalometric image of the patient's profile face before and after repositioning jaw bones by surgery, locates the cheek region, and measures both the amount and the direction of cheek due to changes of soft tissue. The first experiment quantified the results of orthognathic surgery in the cases of both mandible (lower jaw) deficiency (Class II) and maxilla (upper jaw) deficiency (Class III) and visualized the changes in both regions of cheek and mouth using the proposed method. The second experiment calculated the changes in both cheek and mouth regions and compared those averages over patients between two surgey conditions, i.e. one conducted genioplasty for chin reposition in maxilla adjustment for treating Class III and the other did not. The proposed method quantitatively clarified how the soft tissues of cheek and mouth changed after surgery when the maxilla had moved in the treatment and the result was consistent with what oral surgeons have recognized only by looking in the past.; ------------------------------; This is a preprint of an article intended for publication Journal of; Information Processing(JIP).
