Quantification of Facial Fat Compartment Variations: A Three-Dimensional Morphometric Analysis of the Cheek.

Abstract

Cheek contour is a main determinant of facial attractiveness. The aim of this study was to evaluate the relationship between age, sex, and body mass index (BMI) and cheek fat volume in a large cohort to better understand and treat facial aging. The authors performed a retrospective review of the archives of the Department of Diagnostic and Interventional Radiology, University Hospital of Tübingen. Epidemiologic data and medical history were assessed. Cheek superficial and deep fat compartment volumes were measured on magnetic resonance images. Statistical analyses were performed using SPSS and SAS statistical software. A total of 87 patients with a mean age of 46 years (range, 18 to 81 years) were included. The superficial and deep fat compartment volumes of the cheek increased with BMI ( P < 0.001 and P = 0.005), but there was no significant relationship between age and volume. The ratio of superficial versus deep fat did not change with age. No significant difference of the superficial or deep fat compartments was found between men and women in a regression analysis ( P = 0.931 and P = 0.057). Cheek fat volume measurements on magnetic resonance imaging scans using reconstruction software suggest that the fat volume of the cheek increases with BMI but does not change significantly with age. Further studies are needed to elucidate the role of age-related changes of bone structures or sagging of the fat compartments.
