Thermal and elastic response of subcutaneous tissue with different fibrous septa architectures to RF heating: Numerical study
Abstract
Radiofrequency currents are commonly used in dermatology to treat cutaneous and subcutaneous tissues by heating. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells. The architecture of this network, namely density and orientation of septa, varies among patients and, furthermore, it correlates with cellulite grading. In this work we study the effect of two clinically relevant fibrous septa architectures on the thermal and elastic response of subcutaneous tissue to the same RF treatment; in particular, we evaluate the thermal damage and thermal stress induced to an intermediate‐ and a high‐density fibrous septa network architecture that correspond to clinical morphologies of 2.5 and 0 cellulite grading, respectively.
