There are two components of the neck that can contribute to neck aging. Skin laxity or wrinkles and the underlying muscle changes with time. A rhytid is the medical term for a wrinkle and ectomy means to remove. So rhytidectomy is literally removing wrinkles in the neck by removing the extra skin. Another term for a neck lift is “platysmaplasty.” The platysma is the most superficial muscle of the neck and contributes to vertical bands. plasty means to repair. So a platysmaplasty repairs and tightens the muscle resulting in a more defined, sharper neckline.
