Chin augmentation

Definition

A chin augmentation is a surgical procedure to reshape or enhance the size of the chin.

Description

Chin augmentation is usually done to balance the face, by extending the chin in relationship to the nose. Thousands of these surgeries are done successfully each year. Surgery may be performed in the surgeon's office, a hospital, or an outpatient clinic.

X-rays of the face and chin are taken, and used to determine what part of the chin will be operated on.

One surgical approach is to make a cut inside the mouth along the lower gum. This gives the surgeon access to the chin bone. The surgeon uses a bone saw or chisel to make a second cut through the jaw bone. The jaw bone is moved forward to the desired position and wired or screwed in place. The cut is closed with stitches and a bandage is applied. Since the surgery is performed inside the mouth, you can't see any scars.

When only a little bit of chin augmentation is needed to round out the chin, the surgeon may use real bone or an implant made of silicone, Teflon, or Dacron. For this procedure, a cut is made either inside the mouth or outside under the chin. A pocket is created in front of the chin bone and under the muscles, and the implant is placed inside. The cut is closed with stitches and a bandage is applied. The resulting scar is barely visible.

Surgery to correct bite problems can be done at the same time as chin surgery.  

Indications

The best candidates for chin augmentation are people with weak or receding chins (microgenia), but with a normal dental bite. Discuss any expectations of looking and feeling better after surgery with the plastic surgeon before any surgery. Keep in mind that the desired result is improvement, not perfection.

Risks

The most common complications are bruising, swelling, and movement of the implant. Other possible complications include loss of sensation in the chin and injury to teeth. Infection and blood clots are rare. Nicotine from smoking can delay healing.

Expectations after surgery

There is some discomfort and soreness, which is easily controlled by medication. A liquid diet may be advised for a day or two. Light activity can resume the same day as surgery.

Convalescence

Return to work and usual activity is allowed within 7 to 10 days. Within a week of surgery, the external bandage is usually removed.
