1. Do I need and am I suitable for jaw angle and cheekbone surgery? Cosmetic surgery is the icing on the cake, and most of the patients are healthy people with no organic lesions, so it is difficult to answer the question of whether they need it or not. It is difficult to answer the question of whether or not the surgery is needed. The main criteria for determining whether or not the surgery is needed are the psychological needs of the patient and their work life, as well as the results of the doctor’s examination. If necessary, a psychological evaluation will be performed. As for the suitability of the procedure, the final decision should be made by a professional doctor based on a scientific clinical diagnosis and the necessary auxiliary examinations. Women should also avoid menstruation and pregnancy. Patients who have been taking diet pills and other medications for a long time are also advised to stop using them for at least one month before undergoing surgery. 2. How to avoid the risks of surgery? As with any surgery, facial contouring brings you a reshaped and beautiful face while also requiring you to take certain risks, so careful consideration should be given when deciding whether to operate and where to operate. Contouring requires a surgeon with extensive clinical experience and skilled surgical skills, as well as high requirements for hardware. (1) Anesthesia requirements: Safe anesthesia is a prerequisite for successful surgery, and the progress of many major complex surgeries in medicine has been made possible by advances in anesthesiology. Bone grinding surgery is mostly performed intraorally and it is vital to maintain the usual airway from start to finish. (2) Operator requirements: Bone surgery, like soft tissue surgery such as double eyelids and nose pads, is also a very delicate procedure, and in addition to careful pre-surgical design, the operation should be performed with great delicacy and patience. Every step from incision, visualization, hemostasis, osteotomy, suturing to dressing should be done carefully. Currently, contouring surgery is mostly performed using an intraoral incision, with the aim of avoiding external marks. This makes the surgical operation very difficult due to the narrow surgical field. Special revealing pulls are required, preferably with the aid of a cold light source, to facilitate the surgical operation. Nevertheless, it is sometimes necessary to operate under blind vision, which places higher demands on the operator. (3) Team requirements: A successful surgery requires each link to be closely interlocked. In addition to anesthesia and surgical operation, postoperative monitoring and care are also very important, and early detection of problems and timely and effective disposal can avoid serious accidents. 3.The cost of inpatient surgery? At present, the hospital deposit for jaw angle surgery is about 28,000-30,000 yuan, and the deposit for cheekbone surgery is about 35,000. The deposit for chin osteotomy is about 18,000. 4.Is it possible to apply computer simulation before surgery to predict the results after surgery? We can use the appropriate software to analyze CT or X-ray to determine the process of osteotomy and the approximate post-operative results. However, it is still impossible to predict the exact outcome. The human body is a very complex organism, which has a fine and rough side. The nature of the hard and soft tissues of each person is also different, and even the response of the left and right side of the same person will be different. Therefore, we think it is inaccurate and unrealistic to predict the post-operative appearance by computer before surgery. 5.Does the bite muscle need to be removed? The bite muscle removal surgery itself is not difficult. However, it is difficult to control and predict some complications during and after the operation. Clinically, we often see some cases of asymmetry, local unevenness, hemorrhage, atrophy or position change of the bite muscle after the bite muscle is removed, which is difficult to be corrected by surgery again, so our opinion is that the bite muscle should not be operated as carefully as possible. It can be improved with post-operative injection of botulinum toxin. 6.Can we ask the surgeon to remove the bones according to the face shape of the celebrity or do the surgery according to the patient’s idea? This is just a question of direction, we can refer to the celebrity’s face shape and the patient’s request for surgery, but the purpose of our surgery is to be more beautiful and coordinated. The basis of all these purposes is based on the premise of preserving normal physiological functions. Practices that are unrealistic, disregard medical safety and disregard the physiological functions of the maxillofacial skeleton are unacceptable to us. Our view is to develop a safe and reliable surgical plan by combining actual clinical and auxiliary examinations. We will re-sculpt the face on the basis of safety. 7.Will the soft tissues sag? Soft tissue sagging after jaw surgery is rare. Soft tissue sagging is mainly concentrated in the post-cheekbone surgery, which is also related to the texture of each person’s skin, bone structure, surgical operation and the degree of cheekbone reduction. For patients with looser skin and more reduced degree of soft tissue sagging can be improved by temporal uplift treatment. 8.How long is it appropriate to wear the elastic bandage? There is no specific technical statistics on this issue, but according to our clinical experience, it is best to wear it day and night for 1 month after surgery, with intermittent rest in between, for example, with 2 hours to take off 1 hour, which is conducive to the re-attachment of soft tissues and facilitates blood return and reduces swelling. 1 month later, it can be worn at night, and it is best to continue for more than 3 months. We clinically found that the long-term wearing of elastic headgear is beneficial to the shaping of the face and the rejuvenation of the skin. 9.How long does it take to recover from surgery? The surgery recovery is divided into: 1.Phase 1: 2 weeks after surgery, the sutures have been removed and most of the swelling has subsided, so you can carry out your daily work, study and life normally. 2.Second stage: 1-3 months after surgery, most of the swelling returns to the pre-operative appearance, and it is difficult for not very professional personnel to see that surgery has been done. The clinical recovery is achieved, which is in line with the theory of Chinese medicine that it takes 100 days to break a bone. 3.The third stage: more than 6 months after surgery, when the soft tissue swelling, venous reflux and nerve recovery enter the late stage, the vast majority of patients have completely recovered to normal. The resorption and reconstruction of bone tissue is also basically completed, and the postoperative effect is more stable. However, in some rare cases, it takes a longer time to recover. Therefore, clinically we often encounter patients who are worried about swelling and discussing the effect of surgery every day for 1 or 2 weeks after surgery, which is inappropriate, because it is impossible to judge the effect of surgery at this time, and worrying is futile and adds a lot of worries to oneself. Therefore, do not be anxious about this situation, the human body is a very wonderful organism, surgery has a rigorous scientific system, nerves, blood vessels, soft tissues and bone tissues follow the scientific law of recovery. Give it time, it will give you a surprise. 10.Can I recover from nerve damage and lower lip numbness? The surgery where this question appears most often is the chin osteotomy, because the chin nerve is right in the middle of our surgical field, and doing this surgery must carefully protect the chin nerve, which is what the craniomaxillofacial professional doctors have been training for years. We often say: the nerve is very sensitive, as long as you see it during surgery, reveal the nerve after surgery, he will have a reaction, there will be temporary numbness of the ipsilateral lower lip after surgery, but as long as the nerve will continue to recover. However, as long as the nerve continues to recover, it will definitely recover, unless permanent irreversible damage occurs in rare patients with anatomical variants. The length of recovery time varies, most of them can be fully recovered in 1-3 months after surgery, while some of them need 1-2 years. 11.Is jaw angle osteotomy or bone grinding surgery better? This is a question raised by artificial speculation, just like eating with chopsticks or knives and forks, as long as the purpose of eating is achieved, the tool is a secondary issue. Theoretically, each has its own advantages and disadvantages, but it depends on how the operating surgeon applies them. We believe that bone grinding and osteotomy cannot be separated. As long as a good treatment effect is achieved, it is fine. 12.Is there a sense of bone step after surgery? There are two main aspects of this issue, the first jaw angle surgery after surgery, the second is the chin osteotomy after plastic surgery. In the early days of the mandibular osteotomy surgery, there are some surgical procedures do exist the second jaw angle, local unevenness and bone step feeling phenomenon, but after years of clinical and theoretical development, this problem can almost be avoided, the reason is that we currently use the curved continuous osteotomy line, can achieve a very good osteotomy area and unstepped area of the excess, the second jaw angle problem almost does not exist. The feeling of step at the bone joint after chin osteotomy can be vaguely felt by careful touch in the early stage after osteotomy, but it is not observable in appearance. The reason is that firstly, we have improved the osteotomy range of the chin and extended the length of the osteotomy, which can achieve a smooth transition of the broken end of the bone, secondly, the bone surface is covered with thick facial soft tissue, so the step feeling cannot be observed, and thirdly, after 3 to 6 months of bone regeneration and reconstruction, the broken end can be completely bone healing, and the only small step feeling that remains disappears. 13, jaw angle surgery is only the jaw angle surgery? Jaw angle osteotomy is a name that is easily understood by the general public. The exact name of our surgery should be mandibuloplasty, which includes the body of the jaw, the outer plate of the jaw, the lower edge of the jaw and the chin. It is not only the corner, but the overall design and surgical operation of the entire jawbone that affects the shape of the face, to achieve the purpose of slimming the face beauty. 14.Am I suitable for chin osteotomy or chin augmentation? For friends with mild or moderate chin deformity, you can consider silicone or Medpor for chin augmentation. However, for moderate and severe small chin, receding chin and skewed chin, etc., chin osteotomy is needed. The titanium plates and nails used for fixation can be carried for life with little rejection and can pass through flight security freely. If you want to remove them, you can do so after six months. The removal of titanium plates and nails is a very simple and minor procedure.
