Facial asymmetry exists whenever one side of the face does not match the other in size and shape. The most common reason this occurs is due to different development patterns of the underlying facial bones and is most commonly seen in people who have some facial bone development issues such as cleft lip and palate and other craniofacial birth defects. Sometimes it may just be soft tissue only and the facial bones are fairly symmetric. But aside from these types of patients, some people merely have a light or mild facial asymmetry of which the cause is not obvious or will ever be known. In essence, it is just you.
In many cases of facial asymmetry the most common finding or cause is that the lower jaw is different between the two sides. Because the lower jaw is moveable (the only facial bone to do so) and has an L-shape in the back above which the jaw joint hinges, it is the one facial bone that is most prone to having differences between the two sides. Most commonly, these differences are back at the angle area and along the jawline that comes forward. This can create a very visible difference between the jawlines when looking straight forward. It is the most common type of facial asymmetry that I see. Sometimes I will see someone who has a crooked chin, where the chin point if offline, but the origin of the crooked chin usually comes from differential jaw growth between the two sides.
In cases of facial asymmetry it is initally important to make sure that the jaw asymmetry is not best corrected by actually moving the whole jaw and putting the teeth into a better bite relationship. If one is young and the jaw asymmetry is significant, how the teeth come together will determine if this is the best long-term solution. But assuming that jaw bone movement is not a good solution, the more common approach is to correct it with the placement of implants.
Jaw angle and jawline implants can be fairly simple methods of improving jaw asymmetry. These implants are almost always placed through inside the mouth. Off-the-shelf jaw angle implants exist but there is no off-the-shelf jawline implant. Jawline implants have to be fashioned at the time of surgery, usually out of a block or thick sheet of semi-soft material. (Gore-tex or SAM is what I prefer) The key to success with implant augmentation is to be certain of exactly where the jaw asymmetry is. Implants will do little good if they aren’t in the area of bone deficiency or asymmetry. Sometimes this is obvious by feel, other times it may be better to get a 3-D CT scan and have an exact skeletal image to work off of. In rare cases, I have even had a 3-D model made from the CT scan and custom-fabricated the shape of the implants prior to surgery. This is the most exacting method but also the most costly.
When having implants placed for any type of facial asymmetry it is important to walk into surgery with the understanding that the outcome will be better…but not perfect. Surgical facial augmentation with implants is as much an art as it is an exact science.

The use of facial implants for male face enhancment is common and the traditional areas include the chin, cheeks, and jaw angle areas. Every none and then, I get a request or see a patient who really enhancement in a different area of the jaw….the vertical dimension. Making the jawline longer in the vertical dimension to increase lower facial height and put the face in better overall balance. Most of these unusual cases exhibit an underlying jaw deficiency problem, often with a significant overbite relationship at their teeth, indicating a jaw that is both short in the front-back dimension (horizontal development) and in the up and down dimension. (vertical development at the ramus)
In correcting this type of jaw problem, the ideal solution for most of these patients is a course of orthodontics followed by traditional orthognathic surgery. While this may be ideal, most of these patients are beyond their teenage years and do not want to make the multi-year investment of time to make a formal anatomic correction based on the bone. A ’short-cut’ solution is to augment the deficient areas with a synthetic implant. While the actual procedure is not difficult to do, the problem is in finding a commercially-available implant that will match the patient’s problem. When it comes to vertical lengthening of the mandible from one side to the other (wrap-around), there is no such off-the-shelf implant option.
Sometimes a standard chin implant, combined with a jaw angle implant, that is positioned low on the bone below the native bone edge may suffice. But there will be a gap between where the chin implent ends and the jaw angle begins. In some cases, it may work but it is a piecemeal approach that is fraught with problems such shifting of the implants after surgery. (in this case , the jaw angle implant)
A better solution is to have a custom wrap-around implant made off of a computer-generated model. A 3-D CT scan can be done from which an exact replica of the jaw (mandible) can be created. Then a mock-up of the implant (by me) can be done in acrylic to create a one-piece wrap-around jaw implant that sits on the inferior border of the jaw, lengthening it throughout. The acrylic mock-up is then sent to a manufacturer where they make a formal silicone rubber implant. While a lot of work is done on the front end, the implant is easily placed through a small incision under the chin. (it is flexible so it easily folds on itself to be easily inserted through a small incision) It is fixed with a single screw underneath the chin so it does not ever move. It really is nothing more than a long extended chin implant that runs from one jaw angle to the other, but is on the bottom edge of the bone.
I have done this procedure several times over the years and found it to be quite successful. There is some significant cost upfront fron the CT scan, jaw model, and final implant (around $5,000, surgery costs are additional) but it is the best way to go when one is looking for this type of jaw implant)
