What is "behind ear" muscle tightening of neck?

With facelifts and neck lifts, both the skin and muscle are address to rejuvenate.  The excess skin is repositioned and removed.  The muscle is tightening in the cheek and neck to improve the jawline and neck contour.  Additionally, fat may be added or repositioned for facial aesthetics.  Similarly in isolated neck lifts, the skin and muscle are repositioned and "tightened".

A lower neck lift with partial tightening can be done with incisions behind the ear, but this will have a very limited effect in my experience on the upper neck, jawline, and the face.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search.
