Harry Mittleman, MD, Stanford (Calif) University, described a geniomandibular groove implant as an adjunct to facelift surgery at the fall meeting of the American Academy of Facial Plastic and Reconstructive Surgery in Washington, DC. Two factors contribute to the groove lines anterior to the common jowl defect: (1) atrophy of the soft tissue anterior to the jowl, and (2) absorption of mandible in this region. Mittleman demonstrated that aging of the mandible causes not only lowering of the alveolar ridge height, but also resorption of the lateral mandibular border in this area. Merely liposuctioning and tightening the jowl area will not correct the "geniomandibular groove." A jowl and a chin-jowl implant is utilized to augment the geniomandibular groove alone or with chin augmentation. This implant, which is 10.2 to 10.6 cm in length, is inserted subperiosteally through a 1- to 2-mm submental incision. A tunnel is made subperiosteally along the
