The decrease in chin projection frequently accompanied by a loss of vertical dimension is a significant component of the changes associated with aging in the lower third of the face. In addition, there are patients presenting for aesthetic surgery who developmentally have developed chins that are either too weak or strong for idealized perioral facial proportions. The two principal operations designed to add additional dimensions to the chin either in a sagittal or vertical plane are the alloplastic chin augmentation (mentoplasty) and sliding genioplasty. Both procedures are described, including the indications and contraindications for each as well as the operative techniques employed. Methods to reduce the overly projecting chin and the ptotic chin are also discussed.
