In the field of plastic surgery, it is very common to perform filler surgery by transplanting autologous tissues or implanting artificial materials for therapeutic or cosmetic purposes. To measure the safety of a certain filler (implant), it is mainly based on whether it is easy to produce rejection, whether its physical and chemical properties are stable and not easy to change, whether its long-term existence in the human body will have carcinogenic and teratogenic effects, and whether it can be removed completely and safely once problems occur. In terms of commonly used materials, autologous tissues should be the safest, with good histocompatibility and no rejection, which is incomparable to other artificial materials. However, autologous tissues are after all limited and cannot meet all the surgical purposes, so artificial materials should be used. With the development of material technology, the tissue compatibility of the material has been greatly improved compared with the past, and it is also more suitable as a filling material for rhinoplasty from the viewpoint of form and texture. There are also polymer materials such as ePTFE, which have a softer texture, but the relatively high price limits their application. As a beauty seeker, it is important to have a detailed understanding of the hospital and physician before undergoing cosmetic surgery. According to the relevant national regulations, clinics and physicians who perform invasive operations (surgeries) must have the relevant qualifications, and the materials embedded in the human body must pass the test and meet the relevant national standards, and it is illegal to perform such surgeries in beauty salons and some private clinics. There are strict indications for facial fillers In addition to patients with deformities of facial soft tissues caused by trauma or congenital disorders, those who feel that their facial features are not perfect can also be considered for related surgeries. For example, patients with temporal sunkenness can consider using autologous fat extraction for filling or silicone gel implantation to make the temporal area appear fuller bilaterally. For people with low nasal dorsum, short jaw and low cheekbones, artificial fillers can be implanted to correct the defects and make the facial features more three-dimensional. Before and after surgery, you should fully communicate with your surgeon, let him/her understand your own characteristics and the purpose of your consultation, and work out a personalized surgical plan with him/her, be well prepared for the post-operative effects and possible situations, and cooperate with him/her in the pre-operative routine examination. The surgery should be avoided during menstruation to reduce intraoperative bleeding and postoperative swelling. Do a good job of personal cleaning one day before surgery, if you have symptoms of infection in the mouth and nasal cavity, you should wait for recovery before performing chin augmentation, rhinoplasty and other surgeries. Although rhinoplasty and chin augmentation are not very traumatic, postoperative care is also important to recover naturally as soon as possible. The incisions of facial filler surgery are relatively hidden, and the incisions are coated with antibiotic ointment after surgery, exposed, not bandaged, and there will be a small amount of blood oozing, which can be gently wiped away with sterile cotton swabs, and do not touch the wound with unclean things to avoid contamination. On the second day after surgery, it is recommended to use alcohol cotton balls to clean the incision, wipe away the blood scab on the surface of the incision, and keep it dry, wait for self-healing, and remove the stitches in 5-7 days. After surgery, you should quit smoking and avoid alcohol, avoid stimulating food, and eat cold liquid after chin augmentation to avoid incision burns and cracks; you should be careful to wear framed glasses within one month after rhinoplasty to avoid external forces causing displacement of the nasal prosthesis. Because of the rich blood circulation of the face, the swelling is more drastic after the trauma, but the swelling is not painful and fades quickly. This is related to factors such as rough operation, trauma, bleeding, and defective coagulation mechanism of the patient. However, the majority of people do not have heavy postoperative swelling. Generally, it becomes more natural in about 10 days, and it is not even visible that they have done rhinoplasty; for those who have a slower recovery progress, it takes roughly 2-3 weeks, so their own psychological adjustment during the post-operative recovery period is also very important. Special reminder: do not believe in “gold silk beauty” “beauty gold silk” is short for “pure gold collagen high energy beauty silk”. Beauty institutions using these products claim that “this product can remove the harmful nickel elements through nanotechnology, the addition of trace elements and high energy collagen made of gold wire implanted under the skin, can achieve the effect of wrinkle removal.” According to the national “on the law to investigate and deal with unlicensed products” pure gold collagen high energy beauty wire “notice”, “beauty gold wire” is a product implanted in the human body, according to the management of three types of medical devices, the state has not yet approved the “beauty gold wire “products, the market is selling and use of such products are unlicensed products.
