Chin augmentation - series

Toggle: English / Spanish

Normal anatomy

The mandible, or lower jaw, determines much of the facial profile and the alignment of the upper and lower teeth. The teeth must be properly aligned for a normal dental bite.

Normal anatomy

Indications

The best candidates for chin augmentation or genioplasty are patients with weak or receding chins (microgenia), but with a normal dental bite. Expectations of looking and feeling better after surgery should be discussed with the plastic surgeon before any surgery, keeping in mind that the desired result is improvement, not perfection. The facial profile can be balanced by extending the chin in relationship to the nose. Reconstructive genioplasty to correct bite dysfunction can be performed in conjunction with jaw surgery. Thousands of genioplasties are performed successfully each year. Surgery may be performed in the surgeon’s office-based facility, a hospital, or an outpatient facility.

Indications

Incision

One surgical approach is to make an incision inside the mouth along the inferior sulcus (a landmark inside the jaw) to gain access to the chin bone. There is no incision made on the skin.

Incision

Procedure

A horizontal cut (called an osteotomy) is made through the jaw bone (mandible) with a bone saw or chisel. The lower portion of the separated bone is moved forward to the desired position and wired in place. The neurological nerves are carefully protected. The incision is closed with sutures and an external pressure dressing is applied. There is no visible scarring since the surgery is performed through an incision inside the mouth.

Procedure

Aftercare

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