3D Topographical Surface Changes of the Malar Region in Response to Compartmental Volumization of the Deep Medial and Lateral Cheek.

Materials and Methods Volumization of the deep medial cheek (DMC) and lateral cheek compartments were performed on nine cadavers at 1cc intervals up to 4cc. To define the zone of augmentation (ZOA), computer-overlay of interval 3D photographs with baseline surfaces was performed and color projection maps generated. The lower limit was set at 1mm projection change from baseline, as this corresponded to a clinically significant difference. Topographic changes in surface area, projection, and perimeter were studied.
