Abstract
Background
Volume restoration was no more a fresh theory for midfacial rejuvenation. However, lack of knowledge regarding the natural aging process of fat compartments often leads to an insufficient or excessive clinical result. The aim of this study was to reveal the age-related changes in midfacial fat compartments and the correlation between midfacial grooves and related fat compartments.
Methods
This study included 60 Asian females in defined age-based categories. The fat thickness of the infraorbital fat compartment, the nasolabial fat compartment, and the cheek fat compartments were measured with computed tomography (CT) images. Analysis of correlations between midfacial grooves and related fat compartments was performed by SPSS software.
Results
A tendency of fat thickening in the infraorbital fat and nasolabial fat compartments with age was observed. The superficial layer of cheek fat compartments was found to be thinner, and a similar tendency was observed in the medial part of deep medial cheek fat. However, it was thicker in the lateral part of deep medial cheek fat. There was a negative correlation between the fat thickness of deep medial cheek fat and both the severity of tear trough deformity and the nasolabial fold. A positive correlation between the lower third of the nasolabial fat compartment and the severity of the nasolabial fold was found as well.
Conclusion
Different midfacial fat compartments tended to undergo selective hypertrophy or atrophy with aging. The findings of this study suggested that augmentation of the deflated fat compartment and liposuction of the hypertrophic fat compartment can provide a more natural effect in facial rejuvenation.
