Hello, this is Woori Plastic Surgery.
Some people feel stressed when they look in the mirror and see that the center line of their face seems tilted to one side, or that their jaw looks asymmetrical.
In particular, when the corners of the mouth are at different heights while smiling, or when the jawline appears shifted to one side, many people visit for consultation because of concerns about facial asymmetry.
However, facial asymmetry is not always just a matter of facial bone size. In some cases, the position of the jaw and the bite structure also play a role, so an accurate analysis can be important.
The Difference Between Facial Contouring and Double-Jaw Surgery
When people are concerned about facial asymmetry, they often wonder about the difference between facial contouring surgery and double-jaw surgery.
Facial contouring surgery is performed in a way that refines the facial outline, such as the cheekbones or square jaw, whereas double-jaw surgery adjusts the position of the upper and lower jaws themselves.
In particular, when facial asymmetry comes from jaw position and bite issues, there may be limits to how much improvement can be achieved by simply refining the face shape.
Double-jaw surgery can approach the problem by adjusting the positions of both the upper jaw and lower jaw together to create a more balanced facial center line and jaw angle.
Facial Asymmetry Caused by Jaw Position Issues
Facial asymmetry often appears when the jaw is twisted to one side or the facial center line is shifted.
For example, in cases of a protruding jaw where the lower jaw is excessively developed, the jaw may appear pushed to one side, and in cases of a receding chin, the jawline may look less defined, making asymmetry stand out more.
Also, when the positions of the upper and lower jaws differ, as in protruding mouth or a long face shape, facial asymmetry may be accompanied as well.
That is why it can be important to analyze not only the current face shape but also the bite and jaw position together.
A Three-Dimensional Approach Is Important in Double-Jaw Surgery
Facial asymmetry is not only a frontal issue; it can also affect the side profile, jaw angle, and three-dimensional balance.
Double-jaw surgery can be performed in a way that improves the facial line and angles more three-dimensionally while adjusting the positions of the upper and lower jaws.
In particular, it has the characteristic of allowing consideration of the lower face length and facial center balance while making fine adjustments to the angles of the upper and lower jaws.
Therefore, during a facial asymmetry consultation, it is important to check the facial center line, jaw position, and bite condition together.
Surgical Methods That Differ Depending on Symptoms
The direction of double-jaw surgery may vary depending on the current jaw condition and bite structure.
IVRO (intraoral vertical ramus osteotomy) is a method in which natural adhesion is induced after moving the jawbone, while SSRO (sagittal split ramus osteotomy) can be applied as a method that cuts the jawbone and stabilizes it firmly with fixation pins.
Because the appropriate approach may differ depending on the degree of facial asymmetry and the condition of the jaw position, a thorough diagnostic process can be important.
Facial asymmetry is often not just a matter of facial bone size, but is closely connected to jaw position, bite, and even the facial center line.
Therefore, if you are considering improving facial asymmetry, it can be important to first thoroughly analyze the current facial structure and functional aspects, and then confirm through consultation whether it is the right approach for you.
