Hyaluronic acid, also known as hyaluronic acid, is a polymer polysaccharide. Hyaluronic acid has a better biological compatibility, can quickly fill the tear trough, the effect is immediate. However, at present, hyaluronic acid filling can cause serious complications such as inflammatory reaction, infection and necrosis once vascular embolism occurs, so it is recommended to go to a regular hospital for the procedure to avoid irreversible consequences. Autologous fat filling of tear trough is to inject the autologous active fat cells into the tear trough to achieve the effect of filling the tear trough. Autologous fat filling of tear trough will not have any rejection, and the fat cells will survive for a long time after getting blood supply to eliminate the tear trough permanently. However, autologous liposuction may have a low fat survival rate, and multiple fillings are required to achieve the perfect result! Considering that the skin in the tear trough area is relatively thin and wrinkled, my recommendation is to prefer granular fat, especially fine particulate fat filler as a good choice. With the ringing of the bell of 2020, we also crossed into the new year, although it is said that the new year is a new phenomenon, but there are many beauty seekers are still suffering, the Spring Festival is still no boyfriend how to do? What if your family is urging you to get married? If you are also suffering, you may want to see how I use 20 days, you step by step to become beautiful. Many beauty seekers are not satisfied with their facial contour, thinking that their face is too big or too square. At the same time, there are also many candidates complaining with me, I am obviously not fat, why is the facial contour not good? If you want to know the answer to this question, you have to be clear about what kind of face shape we think is beautiful. Oriental face is relatively wide and short, in the aesthetic oval or goose egg shaped face for the most beautiful, requiring a soft facial curve, side view with a beautiful arc. With the increasing perfection of medical technology and the continuous improvement of medical devices, facial reshaping by lowering the cheekbones, jaw angle and chin bone osteotomies can also “create” a desirable face shape. What is the most beautiful face shape? In terms of facial contour aesthetics, symmetry is the first element, followed by the harmonization of upper, middle and lower facial proportions. Often encountered some beauty women requesting face slimming, think that the narrower the face the better, in fact, this is a kind of misunderstanding. Putting aside the technical issues, on an individual basis, the surgery is not the same for each person due to their different facial features. The purpose of surgery is to moderate the size of the facial contour, proportionality, therefore, according to each person’s specific situation to design a personalized surgical program, in order to obtain good cosmetic results. Another misconception is that the more surgeries done, the more pronounced the results will be, which is not true. Sometimes a simple surgery can receive the effect of the finishing touch; on the contrary, the more surgery, the larger, the greater the trauma caused. To create a perfect face, it is necessary to localize zygomatic osteoplasty: zygomatic osteoplasty includes zygomatic bone heightening and zygomatic bone lowering two categories. The former is relatively rare and is mainly used for people who have low zygomatic bones on one side and asymmetrical zygomatic bones on both sides due to various reasons, while the latter is more commonly used for people who have protruding zygomatic bones. Zygomatic bone protrusion can be categorized into simple zygomatic body protrusion, simple zygomatic arch protrusion and zygomatic complex protrusion. Those with simple zygomatic body protrusion can use zygomatic bone grinding to achieve the purpose of lowering the zygomatic bone; while those with zygomatic arch protrusion or zygomatic complex protrusion resulting in the middle of the face being wide should use zygomatic bone osteotomy to lower the method to be corrected. Mandibular Angle Osteotomy: Mandibular Angle Hypertrophy, also known as Mandibular Angle Projection or Square Cheek Deformity, is a special type of face shape that is wide in the lower face due to the overly protruding or outwardly turned bilateral mandibular angles, sometimes accompanied by different degrees of biting muscle hypertrophy, also known as Square Face Syndrome. When combined with chin dysplasia, the lower part of the face is even wider and shorter, resulting in a disproportionate relationship with the upper and middle face, which seriously affects the appearance. According to the oriental aesthetics, oval or melon shaped face is beautiful, so the treatment of mandibular angle hypertrophy is one of the common cosmetic surgeries in craniomaxillofacial surgery. The surgical approach for mandibular angle osteotomy is mainly an intraoral approach, with the aim of leaving no traces on the face after the surgery. There are many methods of osteotomy, including continuous arc osteotomy of the mandibular angle, tangential osteotomy of the mandibular angle, mandibular debridement, mandibular bone grinding, and so on. However, when performing mandibular angioplasty, the choice of surgical method is dependent on the specifics of the patient’s jaw angle, and in most cases is a combination of the above methods. Chin aesthetic plastic surgery: The chin, commonly known as the chin, is an important part of the face, and its own form and its coordinated proportionality with the upper and middle face is one of the most important factors in facial aesthetics, and affects the form and function of the lips. Underdevelopment of the chin bone can lead to pointed mouth, pointed face or bird-shaped face deformity, overdevelopment of the chin can lead to long face or horse face deformity, and deviation of the chin can lead to asymmetry of the whole face. The cosmetic surgery of chin deformity can be divided into chin filling surgery and chin contouring surgery: the former refers to the use of silicone or other biological substitutes after sculpting and shaping placed under the front of the chin bone, in order to increase the length and protruding degree of the chin to improve the facial contour of the surgical method, is mainly suitable for the occlusal relationship between the normal mild and moderate small chin deformity of the orthopedic treatment. The latter refers to the reshaping of the chin by means of chin osteotomy and displacement, which is an ideal method for correcting all kinds of chin deformities, and is suitable for the correction of chin retraction, chin overshortening, chin overlonging, giant chin, and deviated chin. In recent years, it has been recognized that jaw widening is not only caused by protruding mandibular angle, but may also be accompanied by widening of the mandibular body and chin, therefore, it is emphasized that the mandibular angle, the mandibular body and the chin are viewed as a whole aesthetic unit during the surgery, and the concept of comprehensive cosmetic surgery of the jaw has been put forward.
