Every time you look at yourself in the mirror, does your face seem proportional?

The problems of disproportional face are very common, including asymmetric face, square face, and large jaw – all of which are mainly the result of the area around the “jaw” that causes a lack of confidence. The causes of disproportional face can be divided into three major causes, as follow

3 Major Causes of Square Face or “Large Jaw”

1. Genetics

Genetics can be regarded as the main cause of large jaws. It is natural to be born with features similar to your ancestors. Some may even have the face shape with large and prominent jaws since young.

2. Large Jaw Muscles

If you are one of those people who chew gums regularly or eat hard food that requires more effort in biting and chewing, the muscles around the jaw may develop. Overuse of muscles or regular contraction of muscles will naturally make them stronger and larger in size. However, once the muscles are no longer used or exercised, they will become smaller according to the body’s mechanism.

3. Large Jaws Caused by “Bone”

In the aspect of physiology, large jaws are caused by the bone that grows simultaneously with the physiological structure of the body. Some people may have jaws that are too large for their face structure.

Two Techniques of “Jaw Reduction V Line Surgery”

Initially, the jaw condition and structure of the patient will be examined with X-ray, which include the height and thickness of the jaws, the thickness of muscles around the jaw corners, the relationship between the jaws and upper facial bones, occlusion, abnormality of organs around the jaw such as maxilla, teeth, and chin. The x-ray results will be used to support the planning of jaw reduction surgery to be suitable for each individual’s face.​

1. Jaw Surgery is the removal of jawbone, which is suitable for those with a square face or large jaw.

2. V Line Surgery is the removal of jawbone and jawline that is the main cause of square face. V Line surgery is currently very popular amongst those who wish to have a slim and proportional face. This technique will make the jawline narrower, causing the face to appear slimmer in complementary with the chin. It is suitable for correcting asymmetric face that is caused by the jawbone. In addition, this technique is also suitable for those who wish to enhance the shape of the face for an improved appearance. The degree of jaw reduction will be decided by the medical specialist and according to the X-ray results of each individual.
