Zygomatic arch reduction surgery, also known as zygomatic bone thrusting, is used to improve the protrusion of the zygomatic arch, which leads to an excessively wide and prominent midface and sunken temples and cheeks. The surgery is performed using an intraoral and preauricular hairline incision, and the posterior portion of the zygomatic arch is cut and folded inward, and finally fixed with a titanium bone and nail bone plate. This surgery is suitable for people with different degrees of protruding cheekbones and people who simply have high zygomatic arches partially but not high cheekbones. Since it is a surgical operation, the following risks may exist and should be noted: 1. Infection: Due to bacteria in the patient’s mouth and irregular surgical operation, infection may be caused, which requires careful cleaning and disinfection of the mouth before surgery and postoperative application of antibiotics for prevention; 2. Hematoma: If the pressure bandage is removed too early, it may lead to hematoma, so the pressure bandage should be removed about 5 days after surgery; 3. Facial Tissue sagging, enlargement of the lower part of the face, affecting facial morphology; 4. Facial nerve injury, difficulty in opening the mouth, poor bone healing, etc., mainly due to improper intraoperative operation or poor postoperative care. Therefore, it is recommended to go to a professional medical institution and find a professional physician for surgery, which can avoid as much as possible the intraoperative or postoperative hazards and risks, reduce complications, and also shorten the recovery time.
