Before deciding to do cheekbone surgery, you must first determine whether your cheekbones are obviously prominent. Of course, if the prominence is not obvious, you can also carry out cheekbone plastic surgery in pursuit of further perfection, but I believe most people are still unwilling to take risks for such a tiny defect. According to the degree of protrusion and the degree of covering the bridge of the nose and cheeks, the cheekbones can be divided into three levels: one is the protrusion of the cheekbones, and the boundary between the nose and cheeks is covered by the cheekbones from the side; Grade 2, zygomatic body is moderately developed, and nasal-buccal boundary is more visible; Grade 3, the cheekbones are not prominent, the cheekbones gradually turn to the side from the front, and the boundary between nose and cheek is clear. There are two anesthesia methods for zygomatic plastic surgery: local anesthesia and general anesthesia. The operator has no pain during the operation. If it is local anesthesia, you are awake. The method of zygomatic bone shaping is oral approach, with accurate positioning of ultrasonic pen and fine grinding of bone. For those whose cheekbones are indeed hypertrophy, only by surgically removing the hypertrophy part can the problem be truly solved. However, there are three cases of zygomatic hypertrophy, one is protruding forward, the other is protruding to both sides, and the third is protruding from the preauricular mandibular joint. The first two cases must be corrected by surgery to achieve the ideal effect, while the third case is not easy to operate. There are many options for surgical incision of zygomatic hypertrophy, such as scalp coronal incision, intraoral incision, lower eyelid incision, preauricular incision, combined preauricular incision and inner ear incision. The operation of extraoral incision is complicated and traumatic, and there is a risk of facial nerve injury. Oral route, most patients can operate in outpatient department without hospitalization. The operation is simple, less injury, less pain, no damage to the facial nerve and relatively safe. 1, healthy, no organic diseases of important organs, such as heart disease, hepatitis, nephritis, pneumonia and other diseases. 2. There is no source of oral infection, such as dental caries, periodontitis and oral ulcer. 3, female surgery should avoid menstrual period. 4. Routine health checks such as preoperative blood routine, urine routine, chest X-ray and electrocardiogram should also be done. 5. Routine facial front and side photos are taken for postoperative comparison and curative effect evaluation. Conditional can do three-dimensional skull CT. X-ray film of maxilla was taken to understand the development degree of maxillary sinus. Individual cases should take facial models and prepare to measure the bone mass that needs to be removed from the cheekbones.
