Zygomatic plastic surgery: Face shape is also closely related to the height of zygomatic bone. The cheekbones are too high and the face is too angular, and too low is not good-looking. Zygomatic bone shaping is to flatten or grind the prominent or depressed zygomatic bone to beautify the facial lines. Zygomatic reduction is generally suitable for patients with anterolateral facial protrusion. Intraoral incision is often used to separate and expose the subperiosteal zygomatic bone, and special instruments are used to chisel and thin the zygomatic bone designed to be removed before operation, thus reducing the external contour of the face and improving the face shape.
