Zygomatic plastic surgery can reduce the height of zygomatic bone and change the abrupt and ugly face caused by hypertrophy of zygomatic bone. Although cheekbone plastic surgery is the most direct and effective method to change the face shape at present, it can't see the effect immediately after operation. Because there is a swelling period of the wound after zygomatic plastic surgery, the change of facial width is not obvious from the appearance, and some will even be wider. This period generally lasts about 15~30 days. As the swelling subsides, the surgical effect will gradually appear 1~3 months after operation.
