What is Breast Augmentation? Breast augmentation, also known as breast enlargement, is a surgical procedure that involves filling the breasts with implants to enlarge the breasts and restore the beauty of a woman’s physical curves. The development of breast augmentation has restored the confidence and beauty of some women with breast defects. Who is suitable for breast augmentation? Women with underdeveloped breasts and flat breasts without obvious reasons during puberty; spontaneous breast atrophy after pregnancy (or after sterilization); micropapillarism, bilateral breast asymmetry Breast underdevelopment caused by lesions of breast tissues (e.g., infections) or traumas before puberty; and after simple mastectomy with preservation of nipple and areola. In addition, the breasts themselves are not small, but have the following conditions: those who want their breasts to be larger, and their chest contour has the conditions to be enlarged; asymmetric size of both sides of the breasts; those who have mild ptosis and have the desire to increase the size of the breasts. What biomaterials are used in breast augmentation? Biomaterials used in breast augmentation are divided into two categories: autologous tissues <"3">(autologous dermal tissue, autologous fat, muscle, etc.); and tissue substitutes (artificial prosthesis). Autologous tissue filler breast without any rejection, but it has the following disadvantages: increase the body surgery area, increase the trauma surface; limited amount of tissue in the donor area, breast volume increase is limited; autologous tissue is not easy to shape, the shape of the postoperative period is not good or due to the absorption of the volume of the breast will be re-smaller; increased body scarring Silicone gel and gel prosthesis has been widely used in cosmetic breast augmentation since the 1970s. However, after years of observation, it is found that silicone gel prosthesis can cause some people’s immune dysfunction, resulting in scleroderma, lupus erythematosus and other diseases, so it has been rarely used. Moreover, silicone gel and silicone gel breast implants affect the penetration of X-ray, so after using them for breast augmentation, the X-ray examination of the breast and chest will be affected. Saline-type breast implants are filled with saline, which is harmless to the human body. However, when the saline is not enough, the implant is easy to rupture due to the folds in the outer membrane, and the sound of “running water” can be heard occasionally when the position is changed. As saline is filled in open condition, it is very easy to be contaminated, which may cause the formation of mold in saline, and once the prosthesis is ruptured, it is absolutely harmful to the body. The incision problem of breast augmentation? Breast augmentation surgery involves implanting breast implants into the pectoralis muscle of the body, which means that incisions have to be made on the skin, and after the incisions heal, more or less, longer or shorter, they will leave eschar scars. However, breast augmentation patients do not want to leave obvious and easily detectable marks, which is related to the location, length and operation of the incision. The incisions of breast augmentation are roughly categorized into anterior axillary line incision, axillary incision, areola margin incision, inframammary fold incision, and so on. Anterior axillary incision: it refers to the outer side of the breast in the downward extension of the anterior wall of the armpit, which also happens to be the lateral edge of the androgynous muscle. Therefore, in this incision, it is very easy to peel off and form the implantation cavity of the breast implant behind the androgynous muscle, and the tissue damage is slight, and it is easy to control the shape and position of the breasts after breast augmentation. However, the incision here will often form a big esch, which cannot even be covered by bra. Axillary incision: The incision is more hidden, the incision is made at the top of the armpit, the incision is transverse, which coincides with the direction of the skin line, the echidna formed is small, and covered by the armpit hair, so the incision is very hidden. However, since the armpit is farther away from the normal breast, the damage is relatively larger. As the posterior pectoralis major muscle cavity formed by peeling is from top to bottom, it is easy to cause excessive separation of the upper pole and insufficient separation of the lower pole, which will easily form the unnatural appearance of upward breast position and downward nipple after breast augmentation. Areola margin incision: it is the incision entry at the junction of areola and skin. As the incision is chosen on the normal contour line, the postoperative traces are relatively hidden and can be completely covered by the bra. This kind of incision approach for breast augmentation is equivalent to the operation in the normal breast position, so it is easier to fully and evenly peel off the posterior pectoralis major muscle cavity, but the operation more or less destroys some of the normal breast tissues and there is also the possibility of injury to the mammary ducts and the sensory nerves of the nipple. Inframammary fold incision: The inframammary fold is the reflex line formed between the lower pole of the breast and the breast crease. As it is a contour line, the incision here is not very obvious and the operation is simple with little damage. However, it is regrettable that the traces of the operation are exposed and can be found when one pays attention to it. Others: In recent years, with the development of endoscopic surgery, especially the application of endoscopy in cosmetic surgery, saline-filled breast implant breast augmentation can be carried out through an incision of about 1 cm in length at the edge of the navel by using endoscopy. There is also the development of polymer hydrophilic polymer breast augmentation in the last two years, which can be performed without incision, but through an injection needle. What are the precautions for breast augmentation? Before surgery, the patient should be fully prepared psychologically and physically, according to their respective objective conditions . Such as height, weight, age and body shape, choose the right size of implant. After the operation, the patient should follow the doctor’s instructions to insist on massage for 3-6 months, which can effectively prevent contracture from thickening of the periosteum. Remove the stitches seven days after surgery and take antibiotics to prevent infection. It should be noted that, such as suffering from chronic heart disease, chronic hepatitis, chronic kidney disease, collagen tissue disease, breast fibrocystic disease and scar body should not do breast augmentation. Inadequate postoperative appearance: In terms of the appearance of breasts after breast augmentation, no matter how “simulation”, more or less will leave traces of artificial “sculpture”: can not form “cleavage”. Normal breast has 2/3 covered in front of the pectoralis major muscle, 1/3 covered in front of the rectus abdominis muscle and extra-abdominal muscle, and breast augmentation is placed in the breast implant in the male large muscle thickness, so after the operation of the bilateral breasts relatively outward, generally can not form a “cleavage”, for the wider thoracic contour of the person’s performance is particularly prominent. Cannot form the “armpit tail”: the perfect breast outer and upper part of the breast protrudes toward the armpit, forming the “armpit tail”. However, after breast augmentation surgery, the breasts often cannot form the “armpit tail”, so the appearance is not real and vivid, especially for those who have poor breast foundation before the surgery, the performance is more prominent. Unable to highlight the dynamic beauty of the breasts: When walking, the well-developed breasts will flutter slightly with the rhythm of gait, and when the body position changes, the appearance of the breasts will also change, while the breasts after breast augmentation can not, often, show the dynamic beauty of the breasts.
