In some patients, the zygomatic bone area in the middle of the face is more prominent, resulting in a slightly sunken appearance of the upper and lower face, forming a diamond-shaped face with poor aesthetics, and this type of patient can be treated with zygomatic bone inward thrusting surgery. The procedure truncates the zygomatic arch from the root of the zygomatic arch to the front of the temporomandibular joint, makes an L-shaped osteotomy in front of the zygomatic bone, pushes the zygomatic bone and the zygomatic arch inward after the truncation, and uses a small titanium plate and titanium nails for internal fixation after the surgery to avoid the formation of bone non-union. Zygomatic bone inward pushing surgery can be adjusted according to different prominent parts, which can effectively improve the face shape, but pay attention to the risks of the surgery, specifically the following points: 1. Facial sagging: it is generally more common, because zygomatic bone is attached with biting muscle and internal pterygoid muscle, and the muscle loses its pulling effect after bone grinding and inward pushing, which will make the face overall sagging, but with the extension of time, the muscle tissues will be reattached, and the muscle tension can be restored gradually afterwards Impact on periarticular structures: the inner pushing distance is small, and mild pressure can have a slight impact on the periarticular structures; 3. Facial step feeling: due to the wide zygomatic arch at the back, resulting in poor postoperative effect; 4. Impact on mouth function: due to the over-pushing of the inner pushing, resulting in the mandible and rostral protuberance being too close to each other; 5. Flaccid facial muscles: due to the excessive peeling of muscle attachment during the operation, the zygomatic bone can not be fixed in the inner fixation. sagging, zygomatic bone internal fixation is not good.
