Chin surgery, also known as mentoplasty or genioplasty, aims at reshaping the chin either by enhancement or by reduction of the bone.

Men and women look best with certain types of chins. A small chin can make a large nose look even bigger and conversely, a large chin may even make a large nose look tiny for the face. This chin/nose relationship must be harmonious.
Indication
A central consideration in deciding whether chin remodeling is appropriate is whether dental occlusion (the way your teeth meet) is correct.
If dental occlusion is satisfactory, the appearance of the chin can be dealt with by chin surgery alone.
If it is not, orthognatic surgery (jaw surgery) may be needed. The entire lower jaw will be set back or advanced forward, to correct the functional problem in the relationship of the lower and upper jaws.
This process can take as much as two years, because often orthodontic preparation is needed.
Chin augmentation surgery
Chin augmentation surgery, also called chin advancement surgery, can be one of the most striking cosmetic facial procedures. Many individuals have very recessive profiles due to the fact that their lower face and jaw have not developed properly. This is frequently a genetic situation and other family members may exhibit similar traits. In many men and women, chin projection is lost due to aging.

Correction of poor projection of the mentum by chin surgery is desirable in approximately 20% of patients undergoing rhinoplasty and about 25% of patients having a rhytidectomy. However, the patient must often be educated that this deficiency exists and that, with surgery, an overall balanced cosmetic result may be achieved.
Chin augmentation surgery in Agave Clinic is performed via a sliding genioplasty. This is one of the most advanced, precise and sophisticated types of chin surgery. It uses your natural bone and if done properly will not move around at all. This procedure is more involved than placing a chin implant and requires making incisions in the bone and also stabilizing it at the end with space age technology of rigid fixation.
This chin surgery procedure is favored by most oral and maxillofacial surgeons and not liked by other specialists performing chin surgery because of its complexity.
Procedure for a chin augmentation surgery
The chin surgery is carried out under a general anaesthetic and takes about one hour.
Incision
An incision is made inside the mouth, so no scar will be visual on the outside.
Osteotomy (bone cut)
The chin is cut from back to front on both sides, using a powered saw with a special blade to separate the edge of the chin.
Sliding and Fixation
The bony piece is then slided forward and secured with titanium miniplates and screws. These will never be removed.
Although you will be able to feel an abrupt "shelf" tissue will cover your new chin and it looks very natural.
Chin reduction surgery
The purpose of chin reduction surgery is to decrease the size of a chin which ‘juts out’ or is perceived as being too large, in order to give the face a more balanced and aesthetically pleasing appearance.
Width and height chin reduction surgery
A large chin may look acceptable and strong for a male but too masculine for a woman.
An large chin may look acceptable and strong for a male but too masculine for a woman. Notice the feminizing effect of this procedure.
Chin reduction is accomplished either by reshaping the bone with a burr to produce a smooth contour or by removing a small piece of bone and repositioning the chin.
Projection chin reduction surgery
Sometimes a sliding genioplasty is used to change the projection of the chin. The projection of the chin is how much (or little) the chin extends from the face in the profile view. The procedure is the same as in the chin augmentation procedure, except the chin bone is slided backwards.

Procedure for a chin reduction surgery
The chin surgery is usually carried out under a general anaesthetic and can take 1-4 hours, depending on complexity. Sometimes local anaesthetic with sedation may be used.
Incision
An incision is made inside the mouth, so no scar will be visual on the outside.
Osteotomy (bone cut)
The chin is cut from back to front on both sides, using a powered saw with a special blade to separate the edge of the chin.
Width and height chin reduction surgery
A second cut parallel to and a few millimetres over the first one can be made, and a slice of bone removed. This will reduce the height of the chin. The middle part of the horseshoe-shaped bone can be removed to make the chin more pointed.
The bleu areas indicate where bone is removed during a chinplasty.
Projection chin reduction surgery
If the projection of the chin needs to be changed, the tip op the chin is slided backward to correct the problem (sliding genioplasty). This procedure is the same as for a sliding genioplasty in chin augmentation surgery.
Fixation
The bone parts are fixed using titanium miniplates and screws. These will never be removed.
Recovery
After chin surgery a tape will be left over the chin to reduce hematoma. It can be removed on the next day.
The chin will be swollen for about 6 weeks, but even until 6 months postoperative the patient will notice a reduction of the volumes.
There will be little pain.
Complications
Infections are possible but rare and extremely rare is permanent numbness of one half of the lower lip and chin due to damage to the mental nerve.
