title: Evaluation and prediction of the facial appearance after surgical correction of mandibular hyperplasia.
abstract: The response of the entire facial soft tissue to correction of mandibular hyperplasia was evaluated in 25 patients by moiré topography. Postoperative changes were quantitatively analyzed by a computer-aided superimposition technique. Posterior displacements occurred in the lower third of the face. A marked retraction was observed around the chin, but the changes gradually decreased in the coronal and posterior directions with distance from the chin. The upper lip was slightly reduced; however, no direct effect was found in the cheeks. The results of this study constitute a database that, if used in conjunction with an interactive imaging system, would allow surgeons to predict accurately the postoperative appearance of the patient.
