Question:
Can you explain what the SMAS is and what it means to tighten them during a face lift?
Answer:
The SMAS (subcutaneous musculoaponeurotic system) is the extension of your plastysma muscle (the fan shaped muscle that is just under the skin of your neck). In the face it becomes a very strong layer of supporting tissue. It has very thin fibers that extend from it to the skin. If you move the SMAS, you will move the skin. In most face lift techniques this layer is moved or tightened to elevate the facial skin. I most often use a SMAS flap technique which elevates the SMAS about 1-2 centimeters bring the skin with it.
