Facial bone grinding surgery often uses an intraoral incision to separate and expose the zygomatic bone under the periosteum. Special instruments are used to chisel and thin the part of the zygomatic bone designed to be removed before surgery, thereby reducing the outer contour of the face. Improve facial appearance.

Facial bone grinding surgery performs minimal dissection through the intraoral approach, allowing most of the soft tissue to attach to the zygomatic bone and move with the zygomatic bone, thereby completely preventing cheek sagging caused by soft tissue. Using the bone grinding method to reduce the volume of the cheekbones does not change the three-dimensional structure of the cheekbones, nor the position of the cheekbone arch. It can only improve the face curvature in the 45-degree viewing angle direction, and the face width is exactly the same. The volume that facial bone grinding surgery can reduce is very limited. It is only suitable for people with slightly protruding cheekbones, and it can also help people whose cheekbone arches are not very wide. However, facial bone grinding surgery must be chosen carefully.
