Breast augmentation (also known as breast augmentation) is a procedure to enlarge small underdeveloped or underdeveloped breasts. There are 3 common types of breast augmentation surgery: breast implants; breast augmentation with autologous fat transfer; and breast augmentation with injection. There are obvious pros and cons of each method, but the information people learn from advertisements or individual medical institutions for breast augmentation is often more one-sided. For example, the advertisements only say that the method is good without mentioning the shortcomings of this method, and individual doctors who only do breast augmentation will exaggerate the advantages of breast augmentation and avoid its shortcomings. Some will even talk about other breast augmentation methods as being useless. If you want to have breast augmentation surgery, it is necessary to fully understand and carefully compare the advantages and disadvantages of various breast augmentation procedures before surgery. Find a trusted plastic surgeon to learn more or go to several hospitals to listen to the opinions of different doctors, do not trust doctors or institutions that only describe one method as perfect. A, breast implants As early as the 1960s after the birth of silicone implants this method is widely used around the world, is the traditional, mature breast augmentation method; implants have silicone and water bladder. The biggest advantages are: 1. it has been used for decades and is a mature method of breast augmentation; 2. it can be removed completely when not needed. However, this method also has defects: 1. scars will appear with surgical incisions; 2. the feel is different from normal breasts. However, with the development of technology, the surgical incision is more concealed and the scar is smaller; the new level of breast augmentation, under the pectoral muscle fascia (on the pectoral muscle and under the mammary gland), double plane (a large part of the implant is under the pectoral muscle and a small part is under the mammary gland), makes the post-operative appearance and feel better; the shape and quality of the implant are improved, which also makes the formation of the envelope, the implant rupture and other complications less. Therefore, breast implant is the mainstream of modern breast augmentation. Second, autologous fat transfer breast augmentation is theoretically the most ideal breast augmentation method: because there is no rejection reaction, plus the feeling of “real breast”, psychologically very well accepted, but unfortunately: the survival rate of fat transfer is very low at present. It has been reported that the survival rate of autologous fat transplantation for breast augmentation is generally less than 30%, and most of the transplanted fat cells will be necrotic and liquefied. If the amount is smaller, the body can absorb and decompose; if the amount is larger and exceeds the body’s ability to absorb and decompose, the body will form a “package” and “post-operative hard knot”; if the amount is larger, the body will decompose some hydrolytic enzymes and break through to the superficial layer to discharge, if accompanied by bacteria If it is accompanied by bacteria, “abscess” will be formed. Therefore, it is said that autologous fat transfer is the most ideal method for breast augmentation, but also the one with the most complications. Injection breast augmentation is an artificial chemical filled into the breast gap by injection to augment the breast. It was introduced and approved for clinical use in China in 1997, which caused controversies from all sides. 1998, the use was suspended for 3 months, but in January 1999, the State Drug Administration held an expert demonstration in Beijing, “it can continue to be used”. Since 1997, a large number of women have received breast augmentation injections in China, and the vast majority of the results are good. However, due to the simple operation and lax management, it is also used in large quantities even in beauty salons. So there are also many complications: such as infection, bleeding, uneven distribution, hard knots, etc.
