In the early days, zygomaticoplasty was done by making an incision from the scalp, which was more damaging. With the advancement of technology, it has evolved to intra-oral zygoma-zygomatic arch surgery. The current method of plastic surgery involves cutting the bone and pushing it inward and then fixing it so that the candidate’s appearance does not change significantly and the zygomatic arch is still present, but the height and width can be significantly improved. The surgery mainly includes L-shaped, F-shaped or double-L-shaped, and the surgeon will choose the appropriate procedure according to the candidate’s own situation. However, surgery usually involves certain risks, specifically the following: 1, zygomatic zygomatic arch displacement or defect: the appearance of this symptom is mostly related to the improper choice of surgical method, the chance of occurrence is relatively high, most commonly in the zygomatic zygomatic arch front end osteotomy, while pushing the zygomatic arch inside, it is easy to make the zygomatic arch rotate down; 2, zygomatic zygomatic arch sagging after internal pushing plastic surgery: after the zygomatic zygomatic arch front end osteotomy, because of the destruction of its structure The muscles and tendons attached to its surface are prone to sagging. Even after the osteotomy, internal fixation is used, but due to the muscle pull in the area, part of the surgeon will still sag after surgery; 3, facial neuromuscular injury; 4, maxillary sinus injury and chronic maxillary sinusitis; 5, restricted mouth opening; 6, bilateral asymmetry; 7, bone does not heal: mainly due to poor bone alignment.
