the lines of aging or skin folds on either side of the chin & in front of the jowls. These lines are caused by the presence of a ligament between the skin in this area & underlying deeper structures. As adjacent skin descends with the process of aging the skin directly over the ligament stays in place creating this fold. The name comes from the observation that these lines are reminiscent of the lines in the same area on puppets with moveable mouths. This ligament is disrupted & the jowls removed in facelift surgery.
