A platsymaplasty is a procedure to tighten a sagging neck. There is a thin muscle that attaches from the collar bone to the jaw bone. There is one muscle on each side. With age the muscle tends to separate in the midline and sag. Think of the older neck that has two midline bands. A platysmaplasty takes the neck muscle and reattaches it in the midline to provide support and tighten the neck. It can be combined with liposuction in a younger patient’s neck and achieve results and is usually performed as part of a facelift in older patients.
