Breasts are not only a nursing organ, but also an important part of a woman’s beauty. A round and firm breast shape, with a slim waist and belly curve, coupled with a delicate face, this is the image of beauty in people’s minds. However, due to physical reasons, many women still have flat breasts after adulthood, or do not take proper care of them after breastfeeding, resulting in breast atrophy, thus forming the embarrassment of “flying airport”. The best way to solve this problem is through breast augmentation surgery, so let’s learn what the secret of breast augmentation surgery is. The common breast augmentation methods are breast implants and breast augmentation with autologous fat transplantation. Breast augmentation is a method to increase the volume of the breast by implanting a molded artificial breast implant into the breast. It has the advantages of one-time completion, short operation time, realistic feel, and immediate post-operative effect, etc. By choosing different specifications and models, the ideal surgical effect can be achieved. And autologous fat transplantation for breast augmentation is a fat transplantation process in which excess fat from other parts of the body is suctioned out, purified through steps such as cleaning and filtering, and then injected into the breast. There is no incision in the surgery, recovery is quicker and does not affect daily activities. Breast Implants Breast implants are a more applied and technically very mature form of surgical plastic surgery. The surgeon first needs to understand the social as well as natural attributes of the candidate, the candidate’s occupation, personality, attire, hobbies, social circle, etc. so that both parties can reach a consensus on aesthetics and the physician can determine the candidate’s desired goals. Secondly, we need to measure the height, weight, circumference ratio, chest shape and aspect ratio, breast skin condition, as well as the symmetry, sagging, flare, skin texture, elasticity and color of the breast, etc. Simply put, we need to do a good job of doctor-patient communication and pre-operative measurement. There are various types of implants on the market today, and only by choosing the right implant can we ensure a perfect surgical performance. Unsuitable implants may cause post-operative effects, complications and great economic losses. The size of the breast implant should not be pursued as large, but should be determined by the size of the original breast, the size of the breast contour, and the laxity of the breast skin, as the implanted implant is too large, which is not only easy to be seen but may also bring a series of complications. Also, for people with fuller bodies and certain breast tissue, or women with similar breast height and width, you can choose round implants to get a firm and full breast curve, while people with thin chest wall skin and women with mildly sagging breasts after breastfeeding choose teardrop-shaped implants as more appropriate. After anesthesia, we must first choose the appropriate site for the incision. There are three incisions commonly used for breast augmentation surgery: axillary incision, areola edge incision, and inframammary fold incision. The axillary incision is the most concealed, the incision is consistent with the skin folds, and the post-operative scars are extremely inconspicuous, which can meet the needs of some special professional women (such as actors, models, etc.) and has a wide range of application. The areolar incision is small, and the peeling is done under direct vision without any special instruments. After the incision is healed, the areola skin color is dark brown and the nodular areolar sebaceous gland is masked, so the scar is not obvious and meets the aesthetic requirements. For married women with large breasts and a certain degree of sagging, it is more appropriate to choose the inframammary fold incision because there is no breast tissue in the lower part, which does not damage the breast and neurovascular, and it is more convenient and practical to reveal the tissue level and surgical operation. Then a certain cavity is separated to facilitate implantation of the implant. Nowadays, surgeons mostly choose the subpectoral space to place the implant into this space, which can make use of the massage effect of the pectoralis major muscle to reduce the chance of contracture of the envelope, and is far away from the breast tissue, while it is wrapped by the muscle and fascia, so the implant is not easy to reach, which is especially suitable for people with less breast tissue and thinner subcutaneous fat. For women who have some breast foundation after childbirth, choosing the posterior breast gap level is the best choice, first of all, the breast shape is easy to control, the breast position, the appearance of the form is very natural, and the breast is not deformed after the contraction of the pectoralis major muscle. The surgeon should prevent excessive damage, prevent bleeding and hematoma, prevent foreign body from entering the breast augmentation cavity, prevent postoperative breast injury, etc. If improperly handled during the operation fails to stop bleeding completely, or if postoperative drainage is not complete it will cause the appearance of hematoma. During the operation, we should correctly grasp the separation level, moderately separate the cavity, place drainage after the operation, add pressure and fixation, and closely observe the change of breast tension. When stripping the cavity for placement of the prosthesis, attention must be paid to bilateral symmetry. Too high a peeled cavity will cause the upper pole to be too full and reveal an illusion, while too low will not correct mild sagging of the breast. The size of the peeled cavity should be just right, too large a cavity may displace the prosthesis, especially the teardrop-shaped prosthesis, which may cause an upside-down condition; too small a cavity will not work either, as it will cause contracture of the envelope due to the excessive pressure on the prosthesis. In short, the doctor’s rich experience and exquisite technology are the keys to guarantee the success of breast implants. Autologous fat breast augmentation Autologous fat breast augmentation is to aspirate a non-excess fat, filter and purify it, and then inject it into the breast to augment the breast. There are two keys to the success of a perfect autologous fat breast augmentation, first of all, to ensure that the aspirated fat cells are as complete as possible and the fat purification step should be done in the best way, so that one can ensure the survival of the fat cells after transplantation and also avoid the impurities from affecting the breast augmentation effect. Secondly, the surgeon should have a precise grasp of the injection site, the amount of injection, and the level of injection, because fat cells have a certain absorption rate, so it is difficult to play an obvious breast augmentation effect with too little injection, and it is also difficult to make the fat cells viable with too much injection, and it is easy to cause the liquefaction of fat and the formation of breast lumps. The main advantages of autologous fat breast augmentation are as follows: the surgery is simple and can be completed in an outpatient clinic without hospitalization; the recovery after surgery is fast and the scar is not obvious, leaving only pinhole marks; the body can be slimmed and breast augmented in one go; the surgery is safe and reliable as it can be repeatedly injected several times; the injected fat and the autologous breast fat are dissolved into one, so the postoperative feel is good and there is no concern about the real or fake. In terms of surgical indications, breast implants are suitable for almost all women who need breast enlargement, such as breast dysplasia, breast atrophy after childbirth or weight loss, mild breast sagging, etc. Autologous fat transfer breast augmentation is more suitable for women who have enough excess fat in other parts of the body, and whose breasts have a certain volume but are not big enough or have mild breast sagging. Therefore, the choice of which method depends more on personal conditions, there is no best, only the most suitable method for you.
