Chin Augmentation

At our practice in Austin, Texas, chin augmentation (also known as genioplasty or augmentation mentoplasty) can reshape or enhance the chin’s size and position by inserting an implant or reshaping the bone. In most cultures, a prominent chin and distinct jawline are considered attractive facial features. There is actually a science to “sexiness” and universal agreement on what we humans typically find attractive. When it comes to chins, women tend to be attracted to a broad, prominent male chin. Men are typically drawn women with pointed chins and smaller, more delicate jaws.

Is Chin Augmentation Right for You?

Chin augmentation is an ideal procedure for those who were born with a diminutive chin or find that theirs has receded with age. By providing structure and contour to a recessed chin, chin augmentation enhances facial harmony and balance not only from the profile view but also from frontal and oblique views. It can add definition to the jawline while giving the neck a smoother, more refined appearance. Chin augmentation is also often combined with other restorative cosmetic surgeries such as rhinoplasty, neck lift, or facelift. This approach can create an overall well-contoured and aesthetically pleasing face.

The Ideal Chin

How do we determine what is an ideal chin? There are traditional measurements analyzing facial proportions and facial angles that were designed over the years to help in determining what would be an ideal chin for any given face. The most common ways of the determining the ideal chin projection is dropping a vertical line that crosses the root of the nose (between the eyes) and evaluating the position of the chin – the projection should be within 2-mm of that line. Another method is to draw a line that touches the edge the chin and the lips and determine the angle that this line makes with the horizontal facial plane – this angle should be between 75 and 85 degrees.

Left image: Goode’s method of determination of the ideal chin position: a vertical line crossing the root of the nose and the projection of the ideal chin should be within 2-mm of that line.
Right image: Merrifield’s method of determination of the ideal chin: an angle is formed at the intersection between the horizontal plane and another line between the anterior portion of the chin and the most protruding region of the lips. The ideal angle should be between 75◦and 85◦(80◦± 5◦).

If the chin projection is not adequate, it needs to be determined if the issue is whether the patient has a poorly developed chin or has a dental/orthognatic problem (overbite). In patients with a deficient (“weak”) chin, the nose usually appears to be disproportionally large, even though the projection may be appropriate for the length.

The Chin-Nose Balance (& The Nose-Chin Balance)

The nose and the chin have a very special relationship, particularly when looking at a person’s profile. When assessing a patient for the chin size, the nose must always be evaluated. And vice-versa.

When considering chin augmentation, it is important to understand that the chin does not exist alone. A successful chin augmentation depends on consideration of the chin as part of the larger whole of the face. Harmony is especially important when it comes to the nose-chin balance of the face. For example, the nose may appear larger than it actually is if the chin is small. When chin augmentation or rhinoplasty is being considered, the nose-chin relationship, along with entire facial harmony, must be taken into account to make sure balance and beauty are achieved.

The photos above have been morphed as an example of how much the chin position and contour affect the perception of the size of the nose and the overall facial harmony. We can all appreciate how, on the original photo, the chin gives a great balance to the face and nose. However, when the position of the chin changes, either receding or being overly large, it will affect how we perceive the size of the nose and also overall facial harmony and attractiveness.

Our Approach

Chin augmentation can be performed in 2 different ways: (1) Augmentation with synthetic implants a (2) Sliding genioplasty.

The chin implant technique uses a small incision made under the chin. On the other hand, sliding genioplasty is a different approach that involves cutting the chin bone and advancing it forward and possibly downward to achieve the desired results. Once in place, the chin bone is secured using a small titanium plate and screws.

Chin Augmentation with Synthetic Implants

Chin augmentation, or augmentation genioplasty, uses a synthetic chin implant placed in the front of the mandible to augment bone contour. Chin implants have been used successfully since the 1960’s and are the most common method to treat a poorly projected chin. There are several types of materials used in chin implants, the most common ones are solid silicone and porous polyethylene (Medpor®).

Chin implant sizers. These sizers are placed along the chin during the procedure and evaluated to see which one will give the best projection and contour for the patient. Once a decision is made on which size, the actual implant is selected and placed.

There are two ways of inserting the chin implants: (1) through the skin or (2) through the inside of the mouth. Like all synthetic implant materials, chin implants should be exposed to a little contamination as possible. Even though inserting the implant through the mouth prevents a skin incision, intra-oral insertion also exposes the implant to saliva. Due to the fact that the incision to insert the implant through the skin is a small skin incision beneath the chin that is unlikely to result in a visible scar, extra-oral insertion is generally preferred for chin implant placement. In addition to reduced contamination of the implant, skin insertion also results in less tissue dissection with a corresponding reduction in risk, pain, swelling, and recovery time.

Chin Augmentation with Genioplasty

Sliding genioplasty is another method of achieving chin augmentation that involves making a controlled cut (osteotomy) in the bone of the chin itself.

The bone of the chin is then advanced forward (and on occasion downward if increased vertical length of the face is wanted) and secured into position using a small titanium metal plate and screws. This approach must be done using an incision inside the mouth. Sliding genioplasty has a longer recovery time than chin implantation, but the versatility and ability to create changes to the chin in a horizontal and vertical dimension make this procedure very valuable.

In Austin, chin augmentation requires planning and a clear discussion of your desired outcomes and expectations. If you are considering chin augmentation, a skilled an experienced surgeon such as Dr. Antunes can carefully examine your entire face and head to determine what adjustments will create the most natural-looking, aesthetically appealing results. Remember that the chin does not exist independent of other facial features. The best chin augmentation will not only alter the appearance of the chin but also will restore harmony to the entire face.

Chin Augmentation at a Glance

Goal: To bring harmony and attractiveness to the face by enhancing the profile and contour of the chin.

Procedure: Chin implants are inserted through a small incision under the chin. Sliding genioplasty involves adjusting the placement of the chin bone.

Anesthesia: General anesthesia or local anesthesia with intravenous sedation

Length of procedure: 1 to 2 hours

Aftercare: When surgery is complete, the chin will be bandaged for proper healing and protection. Most patients can comfortably go home on the same day and are cared for by family. Pain is not common after surgery. Instead, some patients describe a tightness or numbness along the chin and lower lip. You will be given specific instructions that discuss how to care for the surgical site, which medications to apply or take orally to aid healing, and any postoperative symptoms to watch for.

Recovery: 1 to 2 weeks, on average. The bandages placed after the surgery will be removed during a follow-up appointment. Post-procedure instructions typically include plenty of rest, fluids, and avoiding any sort of trauma to the chin. Dr. Antunes will see you several times during the first 2 weeks after surgery, and you’ll always have direct access to him. During the initial recovery period, you’ll likely have many questions. Having a series of appointments set up in advance eases anxiety about the recovery process. Dr. Antunes’ core objective is to provide a safe, comfortable surgical experience that creates your desired results.


  • Surgery
  • Day 3 to 5: Bandage removal
  • Day 7: Suture removal
  • 1 to 2 weeks: Return to work and social activities
  • 2 to 3 weeks: Return to exercise
  • 4 to 6 weeks: 75% healed
  • 6 months: 100% healed
