Chin Surgery Overview
Chin surgery, also called genioplasty or mentoplasty, is sought by people wanting to augment the shape, height or size of their chin. There are numerous options for chin augmentation including chin implants and genioplasty, as well as non-surgical techniques with injectable fillers. Fillers let you "try out" the look of a larger chin.
Chin implants are most common in chin surgery, however, some surgeons augment the chin area by using your own tissue and bone. Implants can be removed and are thus, reversible. can be done under local anesthesia. The implant augmentation is somewhat predictable. The downside of implants is that it does not reduce the vertical chin height when this is desired. It can increase chin height (the distance from the lower lip border to the bottom of the chin) if placed lower on the mandible (jawbone). Also, an implant can carry risks of migration or infection.
Genioplasty is a procedure that moves the bone forward to increase projection. A genioplasty can provide the appearance of increasing the vertical dimension of the lower portion of the face. It has the advantage of no 'large' implants. Also, the vertical height of the chin can be reduced if necessary. The recovery takes much longer to subside in most chin augmentation cases.
Most patients opt for the chin implant, as the benefits outweigh the risks, especially in comparison to sliding genioplasty.
