A Three-Dimensional Construct of the Aging Eyebrow: The Illusion of Volume Loss

Abstract

Although overall eyebrow volume does not change with age, the relative contribution of fat and soft tissue to the total volume does seem to change. This pattern also differs between males and females. As women age, the fat volume increases and the soft tissue volume decreases. In men, the shift from soft tissue volume to fat volume is less pronounced. Although many clinicians have been drawn to the concept of fat volume deflation as a key element of facial aging, this study does not support this perspective in the eyebrow fat pad. An increasingly refined understanding of the dynamics of facial aging is mandatory for clinical diagnosis and will likely provide the framework from which to develop more innovative treatment options.

Long-Term Evaluation of Eyebrow Soft Tissue Expansion in Thyroid Eye Disease

“…Patients with TED may be subject to the same volumetric deflation of the aging face, but the level of initial expansion is not age dependent. Papageorgiou et al, 15 examined eyebrow volume in 52 healthy individuals and, similar to this study, did not find eyebrow volume to change significantly with age at diagnosis. One could propose that the initial fat expansion in the brow during the transitional stages of TED may offer some buffer for regular age-related deflation changes.…”

Volumetric and Functional Evaluation of the Gluteus Maximus Muscle after Augmentation Gluteoplasty Using Silicone Implants

“…Computed tomographic scans are used for three-dimensional reconstruction, and the bone and soft-tissue volumetry often shows good results. 25,33,34 The isolation of muscle tissue by the difference in tissue density prevents manual selection and variations caused by human error. In the present study, the muscle showed atrophy when submitted to the surgical procedure for the insertion of implants; however, the chart showed an upward curve 3 months after surgery (the time when the patient can exercise), revealing a tendency to recovery.…”

An analysis of Asian midfacial fat thickness according to age group using computed tomography

“…Papageorgiou and colleagues obtained similar results from their study on the 3D volumetric analysis of galeal and brow fat. 4 In their study, men showed a tendency toward fat enlargement with age. However, there was no change in overall thickness with age.…”

“…2,3 However, recently, a threedimensional (3D) volumetric analysis of eyebrow soft tissue revealed that fat volume increased with aging. 4 Hence, this study did not accept the common concept of lipoatrophy as a key element of facial aging.…”
