Although autologous fat grafting is a minimally invasive surgery, the internal wound still needs to be taken care of after the surgery in order to achieve the best surgical results. Here are two parts of how to care after surgery: Fat grafting site 1, 5-7 days after surgery to avoid activities in the transplantation area Fat transplantation is a delicate work, the smaller and purer the particles, the better the blood supply in the injected area, the easier the fat. The small particles just transplanted to the recipient area get nutrition through local infiltration and the growth of new blood vessels, and these new blood vessels are very fragile. In this case, the volume change after filling is not visible in the early postoperative period. When the liquefied fat droplets are gradually absorbed by the body, there will be a significant fat absorption effect, which occurs about one month after surgery, so one month is the peak absorption period after surgery, and the fat that can survive this time can basically survive most of it. Correspondingly, if it is a filler for the cheeks (apple muscle, tear trough, and decency lines), it is necessary to reduce the expression and chewing activities during this period so that the filled fat can grow properly. In the case of temporal (temple) fillers, it is not recommended to have bite muscle toxin injections at the same time, and a soft diet is required after the procedure. This is because when the bite muscle is injected with botulinum toxin the temporal muscle will increase its compensatory activity to help chewing, which affects the fat transplanted in the temporal area. Therefore, experienced surgeons will choose headgear or bandages for about five days to wrap the grafted area after surgery. On the one hand, light pressure immediately after surgery can compress the bleeding caused by the intraoperative needle, on the other hand, it can help fix the fat and prevent displacement, and the third consecutive fixation for five to seven days can remind the patient that this area should be carefully protected, not to move freely, and not to sleep with random pressure. Sometimes when the amount of filling is very small, it is not recommended to apply compression because the transplanted fat may be squeezed out from the eye of the needle. 2, local not hot or ice, unlike other plastic surgery, fat grafting surgery after the fat or ice, hot compresses to promote fat metabolism, fat cells are large, but very fragile cells, not hot compresses. Nor ice, local vasoconstriction is not conducive to fat viability. 3, the eye of the needle to keep dry and clean Small surgery is also afraid of infection, although the eye of the transplant needle are in the hidden parts, but hidden parts such as hair, oral cavity are not easy to clean, so we must pay attention to disinfection protection, until the wound grows well. Do not wash your hair and take a shower when the wound is not healed and let the sewage enter the eye of the needle. 4, six months to avoid strenuous aerobic exercise exercise can reduce fat, if you do not want to transplant in the fat quickly absorbed, transplant surgery within three to six months after the whole body as far as possible do not itch exercise. Because the fat transplanted in will increase or decrease with the fat of the original parts. Questions you may have are: 1. How long does it take for the swelling to go down after surgery? Generally, most of the swelling subsides in about three weeks for patients with full body grafting, and the recovery is faster for those with small localized fillers. The time to reduce swelling is related to the amount of transplantation and the gentleness of the physician’s technique. 2.What should I do if there is local unevenness after surgery? Since the transplanted fat itself is granular, unevenness may occur after transplantation, some of which are temporary and will be improved by subcutaneous fat remodeling in about three months, while some unimprovable ones can be corrected by secondary transplantation. 3.What about asymmetry after transplantation? Because fat grafting is a dynamic process, with the absorption of fat before the final shape, the amount of survival is closely related to the surgical operation, the patient’s own physical condition, and post-operative care. If it is a unilateral filling, it can be corrected by secondary surgery. If the filling is bilateral, it is necessary to pay attention to the sleeping posture after surgery, or the usual way of chewing, etc., and try to achieve bilateral symmetry. 4.How long can I have the second filling? It is recommended to carry out the second transplantation more than 3-6 months after the first transplantation because it takes at least three months for the fat transplantation to be stable, and some patients can have fat regeneration after nine months after the operation. After the early absorption of fat, the living fat cells will further increase in size. Therefore, it is more economical to perform a second graft after stabilization. The best post-operative fixation products are lap bands and elastic pants, which can, on the one hand, stop bleeding by compressing the liposuction area immediately after surgery, on the other hand, help the skin to fit under the skin and promote healing, thirdly, relieve pain and prevent pain caused by coughing and other vibrations, and fourthly, also help local body contouring. Fixed supplies for a large amount of liposuction can generally be worn for three months, and if a small amount of aspiration can be worn until the trauma does not hurt. The entry point should also be kept dry and clean until the eye heals, and if there are sutures, they need to be removed on time, so as not to cause scar growth if they are not removed after the expiration date. In case of inadvertent infection or hyperplasia and local itching, you should never scratch with your nails as this will further stimulate scar growth. The problems you may encounter are: 1. Problems of exudation When a large amount of aspiration is done, there may be light bloody fluid exuding locally in the first two days, which is a normal phenomenon, and the gauze must be changed diligently to keep the wound dry. A small amount of aspiration usually does not occur. 2.The problem of local hardening The aspiration site is hard to the touch in about a month, that is the formation of scars under the skin, which is a normal phenomenon. 3.The problem of numbness of the skin The local numbness of the skin at the aspiration site is due to the possible damage to the dermal nerve during the aspiration, and the nerve will be regenerated and repaired after three to six months. 4, skin bruising Skin bruising and bruising usually occurs in the case of large area aspiration, a small amount of aspiration is not common, and is related to the surgical operation and the patient’s own blood clotting function.
