Title: An Evaluation Of The Biomechanical Properties Of The Superficial Musculoaponeurotic System
Author: Ruff, Matthew David
Abstract: The Superficial Musculoaponeurotic System (SMAS) is a well defined tissue layer of the face commonly utilized in facial surgery, including facelifts. There are several reasons for the utilization of this tissue, including aesthetic results and reliability. Basic to the outcomes for these procedures are the inherent biomechanical properties of the SMAS. Most important for the surgeon in this regard are tissue burst pressure, elasticity, stress-relaxation under load, and creep. This study experimentally determines the biomechanical properties for human cadaveric tissue specimens. As well as defining the cited biomechanical properties, the study examines how they change, as sampled from different regions from the face. This information evaluates the regional elastic properties of the SMAS in relation to the aging face and its surgical correction in facelift surgery. Results of this analysis indicate that the lateral SMAS has sufficient elasticity and strength to sustain the loads typically applied during facelift surgeries. Following the discussion of results, additional studies are recommended to determine the post surgical strength and elasticity of the SMAS, in order to further improve surgical outcomes.
