Abstract

Background: Autologous fat grafting is an increasingly preferred method for aesthetic facial rejuvenation. The authors' group previously described the concept of "lipotopography" as topographic surface changes that occur with fat grafting to discrete facial fat compartments. The purpose of this study was to define the "augmentation zone" of the lateral suborbicularis oculi fat compartment to understand the topographical surface changes following augmentation. Methods: Nine cadaver hemifaces were injected with fat analogue at intervals from 1 to 4 cc. Three-dimensional photographs were taken at baseline and following each 1-cc incremental injection. The interval surface changes were calculated using three-dimensional software including perimeter, diameter, and projection. Results: The augmentation zone of the lateral suborbicularis oculi fat compartment was characterized by a consistent shape and boundary. The shape was an elongated oval bound superiorly by the lid-cheek junction and inferiorly at the level of the zygomaticocutaneous ligament. Vertical and horizontal diameter and perimeter showed initial increases between 1 and 2 cc and then a plateau between 2 and 3 cc. Projection changes demonstrated an initial slow increase from 1 to 2 cc injection followed by nearly linear growth from 2 to 4 cc. Conclusions: Three-dimensional photography and computer analysis provide tools to understand the surface anatomy change in response to fat grafting specific facial fat compartments. Targeted volumization of the lateral suborbicularis oculi fat compartment also results in a unique surface change with consistent shape and anatomical boundaries. The lid-cheek junction and zygomaticocutaneous ligament were observed to restrict the expansion of fat analogue for all injection volumes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.
