During the pre-surgical consultation, the face will be examined, and the expectations and methods of surgery will be discussed. In most cases, chin augmentation can be performed under local anesthesia. Currently, most chin augmentations are aimed at increasing or emphasizing the chin area when the chin is small and drawn backwards. Chin enlargement can be accomplished via placement of silicone implants or other permanent materials, or injection of fat tissue (from another location on your body) or other absorbable filling material. Chin reduction is more commonly performed under general anesthesia, and is achieved via planing or filing, or removal of excess bone (every case according to specific need). Needless to say, the decision is made after the cause of chin protrusion is determined, sometimes necessitating an x-ray of the area.
