Many people with unattractive chins ask the question, “Doctor, what do you think about my chin? Should I get a prosthesis, injectable material or bone amputation?” Similar to this problem, every day to repeat the answer many times, now I will be over the years about the chin plastic surgery options, summarized below, I hope you will help! A, prosthetic implants chin augmentation: common prosthetic implants include silicone, medpor, expansion and so on. This kind of surgery is suitable for those patients with a receding chin, because this kind of prosthesis (especially silicone) is usually placed in front of the lower edge of the jawbone, can only improve the front and rear direction of the deficiency, of course, if the prosthesis is sculpted into a certain shape, placed below the bone edge is also possible, but then the stability of the prosthesis will be greatly reduced. medpor is hard, porous structure, implantation of the oral incision is larger However, its histocompatibility is good and it can solve the problem of short chin to a certain extent. The texture of the expanded body is softer, but once the postoperative infection occurs, it is more difficult to remove. At present, the more widely used clinical prosthesis is silicone, because it has the advantages of stable nature, easy to sculpt, realistic feel, easy to remove, etc., after implantation, if there is no infection, generally can not be removed for life. However, many people who have undergone this procedure will ask the question, “Why is the chin not as curved as before as time goes by, when the chin shape is very satisfactory after the surgery? That is because the bone beneath the silicone will have a certain degree of absorption after surgery, and the amount of absorption varies from person to person, so patients with long-term implants will have a prosthesis-shaped depression underneath the prosthesis when the prosthesis is removed. Second, injection chin augmentation: can be divided into autologous tissue and artificial material chin augmentation. Commonly used autologous tissue is autologous fat particles, fat extraction from their own fat, fat particles centrifugal purification, injected into the chin, there is a certain degree of fat absorption after surgery, the amount of absorption varies from person to person, generally about 50%, can be injected again after six months, generally can be injected 2-4 times. The chin is often more rounded after autologous fat filling chin augmentation, and for those who want a particularly pointed chin, the fat seems to have a less than ideal effect. Artificial material injection chin augmentation has become more popular in recent years, and the commonly used material is hyaluronic acid, which has a more ideal injection effect and a strong sense of three-dimensionality, and can create a sharp chin, but its effect can only be maintained for 8-12 months, after which it has to be injected again to maintain the surgical effect. This kind of surgery is minimally invasive surgery, small trauma, short recovery time, in recent years more and more accepted by the beauty of the beauty! Third, the chin osteotomy: If the chin shrinkage is more powerful, through the implantation of prosthesis has been difficult to achieve the purpose, or patients want to chin longer, you can use the chin osteotomy forward lengthening surgery. This type of surgery requires hospitalization and titanium plates and nails for fixation after surgery, which can generally move the chin forward about 1cm and lengthen it about 5mm. The nail plate implanted in the body may or may not be taken out, and if it is to be taken out, it is mostly done six months after surgery.
