Differing Behavior of Facial Fat Compartments
A recent cadaver study of facial subcutaneous fat compartments provides insight as to how these different compartments behave following injection with soft tissue fillers, shedding light on the effects of aging. Authors Thilo L. Schenk, MD, PhD, et al, used 3D imaging and contrasting agents to identify subcutaneous fat compartments in 30 specimens.
