The SMAS is a superficial fibromuscular structure involved in different facelift techniques. There are multiple ways to work with it: naming it does not describe the entire operation.
Deep Plane refers to approaches that work in deeper planes, releasing and repositioning tissues according to the technique. Extent and strategy vary between patients and procedures.
