Protrusion of cheekbones can be improved by reduction of cheekbones. 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.
