In platysmaplasty (neck-lift surgery), an incision is made under the chin and the skin is lifted all the way to the Adam's apple (larynx). It is lifted several inches wide of the midline. Fat is cleaned off the paired muscles of the neck. Dr. Daniel Kapp, Plastic & Reconstructive Surgery, answered on behalf of MDLIVE. A platysmaplasty is an operation of the muscle of the neck called the platysma. Typically a platysmaplasty is used to treat a sagging neck, also known as a turkey wattle.
