Zygomatic bone is a conical bone that can be divided into two parts: zygomatic body and zygomatic arch, which determine two important visual angles and affect the beauty of the face. After the surgery, not only the cheeks will be reduced greatly and the visual effect will be obvious, but also the surgery will be carried out completely in the mouth, which reduces the wounds. I. Zygomatic bone anterior internal fracture surgery Operation method: cut down the prominent zygomatic bone, remove a small section of the bone ready to be reduced, then fold the remaining zygomatic bone inward, and then use the bone nails to fix it, and the zygomatic arch portion will be completely retained in its original state. Suitable Face Shape: Suitable for those whose faces are not too wide, but whose frontal area protrudes more obviously. Advantages of the surgery: The incision is made completely inside the mouth, so there is no incision on the exterior and it does not affect the aesthetics. Difficulties of surgery: Since the zygomatic arch is not changed, the degree of reduction is limited and not very obvious. II. Posterior internal fracture surgery of zygomatic bone Operation method: use bone grinding method to reduce the volume of zygomatic bone protrusion appropriately and keep it in the original position; the incision is made in front of the ear, and the zygomatic arch is interrupted and folded inward. Suitable face shape: Wide face with some depression at the temples. Advantages: This method can effectively change the position of the zygomatic arch, and the zygomatic protrusion is also adjusted appropriately, so it can make the face shape significantly narrower. Difficulties of surgery: This surgery method is complicated and there are two hidden incisions in the mouth and in front of the ears. Third, zygomatic bone internal reduction surgery Operation method: interrupt both zygomatic protuberance and zygomatic arch, and remove the part of bone to be reduced, move the whole zygomatic bone inward, and then reassemble it. Suitable for face shape: face shape that is wide and prominent in both front and side. Advantages of the surgery: This is the most mainstream method at present, the cheeks are reduced to a larger extent and the visual effect is more obvious; the incision is made in the oral cavity, which does not affect the aesthetic appearance. Difficulties of surgery: the technology is quite complicated, so it needs a physician with very rich clinical experience to complete it safely. Zygomatic bone grinding surgery Detailed process of zygomatic bone grinding surgery: 1. Consultation The patient expresses to the doctor the part he/she wants to reduce and the degree he/she wants to achieve. The surgeon expresses to the doctor the area he/she wants to reduce and the degree of reduction he/she wants to achieve. The surgeon usually makes suggestions and determines the surgical method. 2.Anesthesia There are two kinds of anesthesia: local anesthesia and general anesthesia. In terms of results, when making the incision and performing the surgery, the person under local anesthesia will feel the vibration of the machine, so the doctor recommends the use of general anesthesia. Incision The incision is made on the inside of the mouth near the angle of the jaw or the cheekbone. Bone wax will be applied during zygomatic osteosynthesis surgery to prevent bleeding, and also to prevent muscle bleeding. Zygomatic bone resurfacing surgery is suitable for those who simply have high localized zygomatic bones without prominent or high zygomatic arches. Due to the fact that zygomatic arches are located at the lateral side of the face and the thickness of the zygomatic arches themselves, resurfacing zygomatic bone resurfacing surgery is not suitable for those who have high zygomatic arches. The lower angle of the zygomatic bone plays a very important role in maintaining the normal shape of the human face, so it is forbidden to remove all the lower angle of the zygomatic bone when doing zygomatic osteosynthesis surgery. According to the clinical observation, the effect of simple zygomatic osteosynthesis surgery is often unsatisfactory, so most of the hospitals with higher level of sophistication rarely use the method of simple zygomatic osteosynthesis surgery. After zygomatic osteoplasty surgery, your face can be beautified as a whole. If intraoral incision is used, in order to prevent postoperative infection, fasting for two days after the operation, mainly relying on fluids to maintain physiological needs. After 48 hours, you can start to eat fluids, such as milk, fruit juice, broth, etc. After 72 hours, you can eat half-fluids, such as sour milk, egg custard, rotten noodle soup, rice, etc. Later, you can gradually transition to a normal diet. Later gradually transition to normal diet. Patients do not have to worry about the discomfort during the operation, but the pain after the operation can also be completely avoided. At present, there are advanced “micro-pump” pain-relieving instruments, which can give painkillers continuously and in a small amount within 48 hours after the operation, so that the patient’s recovery is in a pleasant state of mind. 1, after zygomatic bone surgery need to be hospitalized for observation for three to five days to see if your situation is very stable. 2, after zygomatic osteoplasty hand need to use the head mask pressure bandage for five to seven days, in this process, if there are no special circumstances can not be removed, if necessary to remove the bandage in a timely manner, this time to see is to check whether there is no compression of the skin, if it is an intra-oral wound need to be placed on the drainage strip, can be pulled out 48 hours after the operation. 3, in the three months after surgery can not do facial cosmetic massage, can not be rubbed on the face. 4, 6 hours after the operation with mouthwash liquid rinsing until the operation until the removal of stitches. 5.After the surgery, you should eat liquid food until the fifth day, and try to avoid biting hard things in three months, that is to say, don’t eat things chewed with teeth in three months, and eat liquid food or semi-liquid food. 6, zygomatic osteoplasty 7 days after the start of the removal of stitches, do not eat spicy and stimulating food, try to enter the semi-liquid.
