The term “thin face” is a popular term in recent years. It seems that every girl dreams of having a standard small face like Zhou Xun or Zhang Ziyi, but not every girl is born with a beloved melon face or goose egg face. However, the development of modern cosmetic surgery still provides many girls with the dream of a big face to a small face. However, not every friend is able to understand what kind of surgery they need and are suitable for to achieve the purpose of face slimming, as a cranial and maxillofacial surgeon working in the Chinese Academy of Medical Sciences Plastic Surgery Hospital for many years, I feel the need to do some basic Q&A for everyone. First of all, friends seeking beauty should first consult a doctor to do a comprehensive evaluation of their own face shape, to know where the problem lies in order to prescribe the right medicine. Simply put, there are three main reasons for a large face: overdeveloped bones, more soft tissue or both. The surgeon will choose the appropriate surgical procedure to treat and improve the patient’s specific situation. For skeletal problems, we commonly see clinically hypertrophy of the jaw angle development, wide chin bone development, and oversized cheekbones or wide zygomatic arches. The symptoms of severe jaw angle hypertrophy are mainly manifested as a square face or Chinese face, and a milder jaw angle hypertrophy will also look like the lower part of the face is not soft enough, especially when viewed from the side; the chin bone is too wide and the chin is too wide; and the cheekbone is too high or the zygomatic arch is too wide, which is not in line with the aesthetics of the Chinese people, not only does the face plate look big, but also “ke-husband”. The problem of soft tissues Soft tissue problems are mainly manifested by excessive facial subcutaneous fat, overdeveloped cheek fat pad and benign hypertrophy of the bite muscle. Many people do not understand the location of the buccal fat pad, which is actually the location of the proverbial “baby fat” in the bilateral cheeks, and many girls with baby faces generally have buccal fat pad hypertrophy. The easiest way to check yourself is to bite your teeth hard and feel the hard part of the jaw angle on both sides with your hands. Once you determine where the problem lies, the doctor can choose the appropriate surgical method to improve it. For skeletal problems, a professional craniomaxillofacial surgeon is needed because they are trained in craniomaxillofacial surgery and can perform the “bone reduction” surgery for you, but it is very risky for surgeons who are not trained in this area to perform this surgery. Patients with an enlarged jaw angle can undergo jaw angle osteotomy and/or mandibular outer plate grinding or outer plate removal, and there are many different types of osteotomy, the author uses the jaw angle curved osteotomy, the formation of the new jaw natural and smooth articulation, there will be no secondary jaw angle. If the chin is wide, you can directly carry out osteotomy or bone grinding on both sides of the chin to narrow the chin. Generally speaking, many square-faced friends have both an enlarged jaw angle and a wide chin, and the author performs a one-time ultra-long arc osteotomy of the jaw angle and the chin, which can solve the jaw and chin problems in one operation and form a smooth jaw curve. Those with high cheekbones can also undergo zygomatic osteotomy or bone grinding surgery, depending on the specific situation. All of these methods involve an intraoral incision and leave no scarring on the face. For soft tissue problems, there are also corresponding methods to improve, if the bite muscle is thick, the easiest way is to inject botulinum toxin into the bite muscle, which is commonly known as the “slimming needle”, but need to be injected every six months, very simple and safe, belongs to the most effortless cosmetic projects, generally about two weeks can be seen The effect is obvious. If the fat is thick, facial liposuction is needed, mainly according to the different parts of the fat suction, generally speaking, the fat suction needle is relatively thin (1.5-2.5 mm in diameter), and the eye of the needle is relatively hidden, so you do not have to worry about leaving a scar on the face. However, there are still certain risks associated with facial liposuction surgery, and you need to choose an experienced surgeon to perform the surgery. Buccal fat pad partial removal surgery, on the other hand, is a relatively simple procedure that only requires a small 1-2 cm incision in the mouth and can be removed in a few minutes by an experienced surgeon. The above-mentioned surgeries can be done for different reasons to achieve the purpose of face slimming, the main thing is to clarify where your problem lies in order to prescribe the right medicine, of course, there are many friends with multiple problems, so it is necessary to carry out multiple surgeries, the general author is willing to do bone surgery first, and then do facial liposuction after recovery, cheek fat pad surgery can be carried out directly and bone surgery at the same time. Overall, choosing the appropriate hand case according to the specific conditions of the individual, slimming the face is not just a dream. Of course, all surgeries need to be tailored to each patient’s specific situation, and not every patient can be made to have a “V” face or a cone face, our common goal is to achieve the best surgical results while ensuring safety.
