Chin surgery (Mentoplasty)

What is the Chin surgery (Mentoplasty)?

Also known as mentoplasty, or chin implant surgery, chin augmentation alters the shape of the chin by increasing its projection and/or width. An implant — which is made either of solid silicone or a porous biocompatible material – is used to achieve the desired effect.

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.

What is the procedure?

When you need only an implant to round out the chin, 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 surgeon may use real bone or fat tissue, or an implant made out of silicone, Teflon, Dacron, or newer biological inserts. The implant is usually attached to the bone with sutures or screws. Sutures are used to close the surgical cut. When the cut is inside the mouth, the scar is barely visible.

It may also be necessary to move some bones. Then the surgeon will 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 to the desired position and wired or screwed in place. The cut is closed with stitches and a bandage is applied. Because the surgery is performed inside the mouth, you will not see any scars. The procedure takes less than an hour to approximately 3 hours.

What kind of result can you expect?

Chin augmentation surgery is most beneficial to those who have a naturally “weak” chin in proportion to facial bone structure and other features. Chin augmentation is often suggested as a complementary procedure to balance out the facial features of those considering rhinoplasty.

Recovery period and recommendations

Most patients can return to non-strenuous work as soon as 24 hours after surgery, although you should avoid driving while on pain medications. Strenuous work or exercise should not be resumed until at least 2 to 3 weeks have passed. It is important that your chin is not subjected to excessive force or motion during this time, such as with contact sports. Please note that these guidelines can vary widely based on the patient’s personal health, the techniques used, and other variable factors surrounding the surgery.

While recovering, you may experience a feeling of tightness in the chin area, and it is normal for some facial movements to be temporarily restricted or impaired. Any severe pain should be reported to your doctor.

Most swelling should subside within the first 4 to 6 weeks, although your final result may not be fully realized until up to 6 months following your procedure. When incisions are placed on the inside of the mouth, you will have no outwardly visible scars.

Possible side effects and complications

Risks and possible complications include: unfavorable scarring and/or skin discoloration, infection, which requires removal of the implant, excessive bleeding or hematoma, skin or fat necrosis (tissue death), poor wound healing or wound separation, blood clots, anesthesia risks, deep vein thrombosis, cardiac and pulmonary complications, persistent edema (swelling) or fluid accumulation, persistent pain, temporary or permanent change/loss of skin sensation, unsatisfactory aesthetic results requiring revisional surgery, shifting of the implant’s position, possibly causing pressure on surrounding facial structures or nerves, excessive scar tissue formation, firmness around the implant, and/or skin contour irregularities.
