The operation method of grinding cheekbones is to adjust the shape of cheekbones. Generally speaking, it is to reduce the anterior zygomatic bone, keep the posterior zygomatic arch, cut the zygomatic bone into I-shape, remove a small piece of bone to reduce the width, fold the remaining zygomatic bone inward, and fix the zygomatic arch with bone nails, which will remain intact. This practice will use the method of grinding and cutting bones, and the operation will be carried out completely through the mouth, which can really reduce the width of the zygomatic body. Plastic surgery for grinding cheekbones requires delicate operation, so misoperation or improper postoperative care can easily lead to sequelae of grinding cheekbones, as follows:

1. Hematoma after bone grinding: All operations will involve a large number of blood vessels and nerves. Even if the bleeding is completely stopped, it is easy to have the sequelae of grinding cheekbones after operation, which can only be solved by grinding bones and face-lifting repair. So generally speaking, when surgical suture is performed, the doctor will place a drainage tube to draw out the congestion in the wound. This can avoid any sequelae similar to grinding cheekbones.

2. Left-right asymmetry: In the process of grinding cheekbones, doctors need to calculate the width of the resected bone very accurately, but the face of the human body itself is not completely symmetrical. If the doctor is not skilled or negligent, the width asymmetry between the two sides will increase.

3, facial numbness: when performing surgery on the mandible, it is easy to hurt the mandibular nerve and directly dominate the perception of the lower teeth and lips.
