Chin augmentation using surgical implants can alter the underlying structure of the face, providing better balance to the facial features. The specific medical terms mentoplasty and genioplasty are used to refer to the reduction and addition of material to a patient’s chin. This can take the form of chin height reduction or chin rounding by osteotomy, or chin augmentation using implants.
This operation is often, but not always, performed at the time of rhinoplasty to help balance the facial proportions. Chin augmentation may be achieved by manipulation of the jaw bone (mandible) and augmentation utilizing this technique usually provides a more dramatic correction than with the use of prosthetic implants.
Chin implants are used to build a better profile.
Chin augmentation is still popular because it is a relatively easy operation for the patient while producing noticeable changes in the silhouette of the face.
Cosmetically, there is a profile of an ideal vertical line from the forehead which passes through the nose to the horizontal base of the chin. If the chin goes beyond this line, it is protruding. If the chin is located behind this line, it is receding.
In case of excess fat, a bit of liposuction is used before beginning the genioplasty procedure.
There is complementarity between the chin and the nose. This is why rhinoplasty is often performed at the same time as chin surgery to give a matching set. The combined operation is called profiloplasty.
If chin positions anomalies result in lesions of the lower gums with teeth that might come loose, or problems with dental articulation, such as discomfort when closing the mouth, the patient will be sent to see a smile specialist, who will treat the whole lower face with maxillofacial surgery techniques
According to the surgical technique used, the operation of the chin is done under anesthesia, local or general, with one night of hospitalization or ambulatory and lasts between half an hour to an hour and a half.
The incision is hidden in the mouth on the lower gum or it is done very discreetly under the Chin.
Moving back a protruding chin
Two techniques are possible:
- Reducing the bone of the jaw: The surgeon files down the lower edge of the mandible in order to decrease the projection of the chin.
- Osteotomy of the drop in the chin: The surgeon cuts the excess bone and then reattaches the front part of the chin by using metal plates and screws.
Advance a receding chin
Three techniques are possible:
– a Chin implant placement: there are either silicone or Medpor (POREX) prostheses. These two types of implants with good results. The choice depends on both the aesthetic failure to correct, the wishes of the patient and the habits of the surgeon. Chin implants also have various forms: central prosthesis, prosthesis with small side wings, etc. The surgeon then inserts the chin implant into a space tailored to the level of the bone of the lower jaw. The prosthesis is concealed by the thickness of the fat and muscles of the chin.
– The progress of the chin osteotomy: the surgeon cut the chin bone in the horizontal direction in order to create a bone fragment that is then advanced and fixed in the position desired using pads and metal screws.
– The bone graft: the surgeon takes the transplant he needs on the bump in the nose when he made a profiloplasty or on the skull, the basin, etc. to reshape the chin.
Genioplasty is a painless procedure. The patient can move the jaw safely. He wears a bandage under the chin modeling for five to eight days. There are blue for seven to fifteen days and edema for ten to twenty days. It is advisable to eat semi-liquid or soft food and preferably cold the first two days. The recovery in activity is done after eight days.
The result: Reshaping the chin
The result is visible immediately and takes its final appearance after three months, until the swelling subsides.
