The “melon face” is the main concept of Chinese and Asian aesthetics, historically and currently most people think that “melon face” looks better than “square face” (especially for women). Bone cutting of the jaw angle and jaw edge is the only effective way to improve the shape of the face and make it “melon face” or close to “melon face”. The size of the “face plate” depends not only on the size of the jaw bone, but also on the size of the cheekbones and zygomatic arch. Some people with a wide face plate need to remove not only part of the jawbone, but sometimes part of the cheekbone and zygomatic arch in order to completely change their face shape. Chinese face shape is generally narrower than European and American face shape, but the phenomenon of enlarged jaw angle is also very common in China, but not all people may have a request for surgery for various reasons, such as some may be afraid of the pain of surgery, some think it is unnecessary, some because of economic problems, and in addition most people may not recognize where their own defects are. In fact, the general face shape improvement is precisely the surgical indications of orthognathic surgery, which is called “the art of face sculpture”, and these procedures have been proven by years of clinical practice to be safe, reliable and effective ways to improve the appearance. At present, it has become popular in Korea, Japan, Taiwan and Hong Kong. Some people already have a good-looking face, but if the small and inconspicuous jaw angle is removed, they will look more beautiful. Therefore, it is not necessary that only people with enlarged jaw angle are suitable for this surgery, even people with high requirements for face shape can also undergo this surgery, but the decision must be made after diagnosis and consultation by an experienced doctor.
