High zygomatic osteotomy usually adopts oral incision, which is suitable for beauty seekers with anterolateral facial protrusion. The zygomatic bone is separated and exposed under the periosteum, and the zygomatic bone designed to be removed before operation is chiseled and thinned with special instruments, thus reducing the external contour of the face and improving the face shape. The biggest advantage of this kind of operation is that there is no scar and no trace after operation.

In addition, the curvature of zygomatic arch is too large, which is also one of the main factors causing "face width". Therefore, if the upper part of the face looks thinner, it is necessary to interrupt the zygomatic arch to fold inward. But be careful not to affect the adjacent temporal joints, so as not to affect the opening and closing of the mouth.
