Chin surgery, or mentoplasty, is a surgical procedure to reshape the chin either by enhancement with an implant or reduction surgery on the bone.
Plastic surgery, and other minor office procedures, can often be performed on the lower jaw line and chin area to improve proportions of the face and to help with one's confidence and self-esteem. These types of interventions are frequently suggested by board-certified plastic surgeons to improve the harmony of facial features and improve the chin/jaw/cheek/forehead balance.
Sometimes bone from the jaw itself can be moved forward in an operation called a mentoplasty or genioplasty. Alternatively, shaped silicone implants can be used to give more projection to the chin. Conversely, bone can be removed to decrease an overly projecting chin. Furthermore, modifications to the upper and/or lower jaw can be advised for improved chewing dynamics and occlusion—or how the teeth fit together. These operations can range from simple to very complex.
