Chin Surgery (Mentoplasty)

Chin surgery refers to the surgical reshaping of the chin, either by enhancement or reduction. It can be performed for aesthetic purposes, to give patients better facial proportions, or for reconstructive purposes, to correct congenital or injury-related chin malformations.

Chin enhancement or augmentation is performed to increase the size and prominence of small or receding chins, characterized by the condition called microgenia. This is achieved either by inserting an implant under the chin’s skin, or by moving a piece of jaw bone forward, which is a technique called sliding genioplasty.

Meanwhile, chin reduction is performed to decrease the size of oversized or protruding chins. It can be done through direct reduction, in which excess bone is removed through an incision. Alternatively, a backward sliding genioplasty, which is similar to that in chin augmentation except for the fact that it involves a backward mobilization of the bone segment, may also be utilized.

Prior to the actual surgery, the surgeon will conduct a thorough analysis of the patient’s face, taking into consideration his or her complete dental and medical records. This is to gauge whether the problem of facial disproportion can be corrected using chin augmention or reduction techniques, or whether said problem is of such serious extent as to require corrective jaw surgery or orthognatic surgery.

When done correctly by an expert plastic surgeon, chin surgery resolves issues of asymmetry and disproportion on one’s facial features, and can also improve the jaw’s functional capabilities. The procedure may be complemented by nose surgery to ensure optimal proportions, and may be covered by medical insurance if performed for reconstructive purposes.

What patients need to know about Chin Surgery


For chin augmentation using implants, an incision is made under either the chin or inside the mouth, and through said incision, a pocket is made in the connective tissue inside the chin close to the bone. A sterile implant is then inserted into said pocket before the incision is sealed.

For direct chin reduction, excess bone is removed through an incision made under either the chin or inside the mouth.

For a sliding genioplasty, a part of the jawbone is first cut and removed, and said part is then moved forward or backward, depending on whether the procedure is to augment or reduce the chin. The mobilized segment is subsequently held in its new location using metal plates and screws.
Length 1 to 2 hours
Anesthesia Local or general
In/Outpatient Usually outpatient
Side Effects - Slight and temporary pain and swelling
- Temporary feeling of tightness or stretching around the jaw
- Need to maintain a soft or liquid diet for several days
- Need to avoid unnecessary touching of or sleeping on the chin area
Risks - Infection
- Bleeding
- Allergic reaction
- Chin deformity due to infection
- Paralysis of the chin muscles due to injury to the major nerve in the chin
- Bone erosion due to implant
- Implant dislocation or displacement
- Undercorrection or overcorrection of the defect
- Failure of the transposed bone segment to properly reconnect with the other jaw parts
- Damage to teeth roots
- Hematoma
Recovery Patients may return to work in 7 to 10 days, but need at least three weeks before they can resume strenuous physical activities. Pain relievers and antibiotics may be prescribed to treat discomfort and reduce the risk of infection, respectively. Surgical dressings may be removed after 2 to 3 days, while stitches, within 1 week. Patients are also advised to rinse their mouth with hydrogen peroxide and warm water for two to three times a day, and to avoid unnecessarily touching and/or sleeping on the chin area. Swelling will completely subside in about 1 month.
Duration of Results For chin augmentation using implants, results are not permanent as the implant may be removed or changed. Results are more or less permanent for chin augmentation using sliding genioplasty, and for chin reduction.
