Full and perky breasts are not only a sign of sexiness, but also the key to a woman’s curvaceous beauty. Flat breasts cause adult women to suffer and lose their confidence, and the ever-sophisticated breast augmentation surgery has brought hope to flat-chested women. Currently, the most common and safest method worldwide is still breast implant augmentation, and it is estimated that more than 3 million women have undergone breast augmentation surgery in the United States alone, with tens of thousands of new recipients still coming in each year. In China, women generally have small breasts because of their race, so the number of people who want to have their breasts surgically augmented is by no means a small number. There are many methods of breast augmentation, but the most commonly used and safe method is breast augmentation with implants. Silicone breast implants have been used for nearly forty years now. Silicone breast implants have a natural feel, simple surgery and good results, so they are favored by doctors and candidates. There is a difference between elemental silicone and polysilicone. Medical-grade silicone is usually a special polymorph of high-purity dimethylsiloxane. It is one of the least biologically reactive materials available for medical use. All breast implants are based on a silicone rubber shell consisting of fully polymerized silicone gel with a non-crystalline silica filler, which can be single or double-layered, smooth or rough, or covered with polyurethane foam; filled with various concentrations of silicone gel or sterile saline, called silicone gel implants and saline implants, respectively. For safety reasons, most of the current silicon capsules of breast prostheses use new processes and formulations that are leak-proof, and are made with rough surfaces, called gross surface prostheses, which minimize the incidence of contracture of the envelope. The physical formation of silicone gel is like a sponge-like matrix composed of cross-linked single silicone macromolecules filled with various chain lengths of silicone oil, if silicone oil penetrates through the silicone rubber capsule to the outside of the capsule, it is harmful to the human body, so the United States had banned the use of silicone gel prosthesis, only allowed the use of saline prosthesis, with the improvement of the process, gradually solved the problem of leakage and rupture, improve the safety, recently the United States announced the lifting of the ban on the use of silicone gel prosthesis. A, silicone gel breast implants placed in breast augmentation is a relatively safe surgery, but there are a variety of complications, common surgical complications are: 1, periosteal contracture: is the most common complications. Silicone implants are foreign to the body and are likely to stimulate the surrounding fibrous tissue to proliferate and form an envelope, which is generally not contracted. The cause of contracture is not well understood and may be related to the quality of the prosthesis, the size of the separation space, postoperative hematoma, infection, and individual differences. Contracture can occur shortly after surgery or several years later, asymmetrically on both sides or unilaterally. The clinical grading created by Baker’s (grades I-IV) is still the most practical grading method. Contracture of the envelope is not a health risk per se, except for the possibility of interfering with mammography, but it does reduce the surgical outcome. Evaluation of the available data with current techniques and equipment reveals that over 90% of cosmetic patients and approximately 85% of reconstructed patients have breasts that can achieve Baker grade I or II, are relatively soft and imperceptible to the prosthetic form, and generally do not require treatment. However, a small number of patients develop severe contracture and hardening, and the shape of the implant can be seen. Once the contracture hardens, closed or open periosteotomy is required, and if the lesion is still not released, periosteotomy is required. 2.Prosthesis rupture: not common, but serious consequences. It usually occurs about 10 years after breast augmentation and is characterized by breast discomfort or pain. Once the rupture of the breast implant occurs, the implant needs to be removed in time for surgery. At present, the good quality of the prosthesis, generally rarely occur rupture phenomenon. 3, other: less common. Such as bleeding, hematoma formation, breast pain, breast implant displacement, asymmetry, poor shape, calcification of tissue around the implant, etc. There is no evidence about cancer and malformation. Second, breast augmentation surgery is not very complicated and is a relatively mature routine surgery. As a candidate who needs breast augmentation, before doing the surgery, you should consider the following issues: 1, go online to learn some knowledge about breast augmentation surgery, so that you can have a good idea of your chest. 2, choose the right hospital and trustworthy doctor, and communicate. 3.Psychological and physiological preparation: full estimation of the effect after surgery and the degree of acceptance by yourself and others, mental preparation and ability to bear the risks of surgery, financial ability, sufficient recovery time for surgery, etc. There are no serious diseases affecting the surgery, and the surgery cannot be done during menstruation. 4, the choice of surgical method, in fact, is mainly the choice of surgical incision and the choice of breast implant placement level. At present, the commonly used incisions are axillary incision, areolar incision and inframammary fold incision, each of which has its own advantages and disadvantages, and the levels of breast implant placement are mainly the posterior mammary space and the posterior pectoralis major muscle space. The choice of which incision and which level should be determined according to your own conditions, personal desires, and doctor’s recommendations, which can be discussed with your surgeon. 5, the choice of prosthesis, including the choice of size, shape, type and brand. Selecting the size of the implant generally needs to be considered from several aspects: (1) natural aesthetic: in line with the aesthetic concept accepted by the public, that is, the size of the breast is proportionate to the body fat and thin; (2) personal aesthetic concept: each person may have different requirements for aesthetics, preferences, occupation, etc.; (3) personal physical conditions: including height, weight, the state of breast development (breast development size morphology position, other soft tissue thickness, the (3) personal physical conditions: including height, weight, breast development status (size and location of breast development, thickness of other soft tissues, tissue elasticity, breast shape, etc.), etc. When choosing the implant before surgery, the patient needs to fully communicate with the surgeon and make clear his or her wishes and requirements, while the surgeon will check the patient’s body condition and propose a reasonable plan, and both sides will agree on the final decision. The choice of shape can be disc-shaped, teardrop-shaped, high protrusion-shaped, etc., according to the different circumstances discussed with the doctor. The types of silicone gel prosthesis, saline prosthesis, glossy type and hairy type, saline prosthesis has the possibility of leakage, although leakage is harmless to the human body, but the morphological changes still need to be re-operated, due to the full estimate. Hairy implants have less chance of post-operative membrane contracture than glossy implants, but are much more expensive. Breast prosthesis brand is very much, there are domestic, there are imported, you can choose a quality breast prosthesis according to their economic strength. 6, post-operative care Breast care in the first few days after surgery is very simple, do not shower during this time. You will need a support bandage or tape, which can be removed after a few days and replaced by a support bra. Once your sutures are removed, your doctor will instruct you to use some topical medications early on to prevent scar growth. Elevation of the upper extremities is prohibited for 2 weeks after breast augmentation with axillary incisions to prevent the implant from shifting outward and upward. In addition, early breast massage should be performed with the aim of allowing some movement of the implant and avoiding the occurrence of encapsulation contracture.
