Augmentation mentoplasty; Genioplasty
A chin augmentation is a surgical procedure to reshape or enhance the size of the chin. It may be done either by inserting an implant or by moving or reshaping bones.
Surgery may be performed in the surgeon's office, a hospital, or an outpatient clinic.
You will have x-rays taken of your face and chin. The doctor will use these x-rays to determine what part of the chin to operate on.
When you need only an implant to round out the chin:
It may also be necessary to move some bones:
Surgery to correct bite problems can be done at the same time as chin surgery.
Chin augmentation is usually done to balance the face by making the chin longer or bigger compared to the nose. The best candidates for chin augmentation are people with weak or receding chins (microgenia), but who have a normal dental bite.
Before your surgery, discuss your expectations about looking and feeling better with the plastic surgeon. Keep in mind that the desired result is improvement, not perfection.
The most common complications of chin augmentation are:
Other possible complications include:
Rare side effects include:
Although most patients are happy with the outcome, poor cosmetic results that may require additional surgery include:
Nicotine from smoking can delay healing.
You will feel some discomfort and soreness, which you can easily control with medication.
You may feel some numbness in your chin for up to 3 months, and a stretching sensation around your chin for 1 week. Most of the swelling will be gone by 6 weeks, depending on the type of procedure you had.
You might have to stick to a liquid or soft diet for at least a day or two.
You'll probably have the outside bandage removed within a week of surgery. You may be asked to wear a brace while you are sleeping for 4 - 6 weeks.
You can resume light activity the day of surgery. You should be able to return to work and your usual activities within 7 - 10 days. Your doctor or nurse will give you specific instructions.
If the cut was made under the chin, the scar should not be noticeable.
Most implants are good for life. However, implants made from bone or fat tissue that was taken from your body will sometimes be reabsorbed.
Because you may have some swelling for months, you might not see the final appearance of your chin and jaw for 3 - 4 months.
