There are obvious differences between bone grinding and bone cutting mainly in surgical methods, surgical principles, scope of application and other aspects. 1. Different surgical methods: Bone grinding surgery is often done after local anesthesia in the jaw area to make small incisions, through the subperiosteal stripping way to remove part of the bone, while bone cutting surgery is often done after general anesthesia in the mouth to make an incision to eliminate part of the zygomatic bone. 2. Different surgical principles: the principle of bone-setting surgery is to remove part of the cheekbone, which can generally change the face shape slightly, while bone-setting surgery mainly removes the excess bone and the change of the face shape is more obvious. 3. Different scope of application: Bone resurfacing surgery is suitable for people with lower cosmetic needs, while bone cutting surgery is suitable for people with obvious bone deformity, larger facial bones and higher cosmetic needs. You should go to the regular hospital for the relevant surgery, and if you feel uncomfortable after the surgery, you should consult the doctor in time and take active treatment, so as not to miss your condition.
