Chin liposuction is most frequently sought by those who have an amount of fat in the area beneath their chin and hanging below the jaw, a condition sometimes referred to as “double chin.” A plastic surgeon uses a tube called a cannula to suction out the unwanted fat. The incisions used for this procedure are relatively small, and only local anesthesia is needed. After surgery and healing time, patients see a firmer appearance in their profiles, with tighter-looking skin under the neck.
