1. The appearance of congenital developmental malformation is mainly manifested as hypertrophy, high protrusion or low flatness of cheekbones. The phenomenon of zygomatic hypertrophy and deformity is more common in the East. It can be unilateral or bilateral, and bilateral is more common. Bilateral patients are not completely symmetrical, and sometimes one side is slightly higher than the other, so cheekbone plastic surgery is needed. 2. Zygomatic deformity is common in westerners, which shows that the zygomatic part is not full enough and the contour line of the upper part of the zygomatic surface disappears. Depression under cheekbones, deepening nasolabial groove and skin wrinkles often appear, and the above symptoms are more obvious in the elderly. At this time, cosmetic surgery for cheekbones should also be done. 3. Deformities caused by diseases, such as inflammation and tumor of zygomatic bone or adjacent tissues, can cause defects and deformities of zygomatic face and even disfigurement. This deformity can be repaired by zygomatic plastic surgery, thus improving the shape of zygomatic surface and playing a cosmetic role. 4. Traumatic deformity of zygomatic bone or zygomatic arch can be different according to fracture type, degree of injury, severity of injury and whether there is peripheral soft tissue injury at the same time. According to different situations, different surgical methods can be used for repair and improvement.
