Beauty is the pursuit of all ladies. As we all know, one of the most important criteria of female beauty is to have full, well-proportioned and elastic breasts. However, not all women can have ideal breasts, due to congenital or acquired reasons, there are often deficiencies, causing great mental pain. Fortunately, this is not irreparable. The development of modern plastic surgery has made it possible to treat all kinds of breast deformities significantly and effectively. Moderately full breasts are a symbol of femininity. The majority of cases of micromastia are due to congenital underdevelopment, while a few cases are due to atrophy after breastfeeding. Breast augmentation has evolved to be a safe and convenient procedure that simply involves placing an artificial material underneath the mammary glands or the pectoralis major muscle to augment the breasts. The surgery can be performed through three incisions in the lower breast crease, areola or armpit, usually 3-5cm long, and the scars are very hidden after healing. Breast filling materials are currently used in two main categories: silicone gel breast implants and saline-filled breast implants. The former has a better feel and shape, but is slightly more difficult to place, with a larger incision, and there are concerns about the adverse effects of silicone gel on the human body; the latter is easier to place and remove, with a smaller incision and greater safety, but has a slightly worse feel. It is worth mentioning that now there is a method of breast augmentation through liquid material injection, although it seems to be faster and less traumatic, but once complications arise, the consequences will be serious, and even to remove both mammary glands, so it is not worth promoting. Breast loss caused by various reasons is very common, and the most important one is breast loss after radical mastectomy for breast cancer. Due to the continuous progress of modern treatment methods, the survival rate of breast cancer patients has been greatly improved, and the requirements for the quality of life have been raised accordingly, and the development of breast reconstruction has become more and more popular. The most basic indication for breast reconstruction is that patients have the desire and requirement of restoring the shape of the breast, and benign breast tumors, congenital breast dysplasia such as Poland’s syndrome, etc. are all indications for breast reconstruction. For post-mastectomy breast cancer patients, the timing of breast reconstruction should be chosen according to the specific situation when the general condition is good and there is no disease of vital organs. Timing of breast reconstruction after mastectomy Immediate breast reconstruction is feasible after radical mastectomy for stage II breast cancer; radical mastectomy for stage III or IV breast cancer can also be carried out after one year of systematic anticancer treatment without metastasis or recurrence and in good general condition. Preoperative preparation A comprehensive examination should be carried out before surgery. Over-obesity, radiological injury of chest wall, diabetes and smoking are regarded as risk factors for this surgery. If a transverse rectus abdominis muscle flap is used in the lower abdomen, upper respiratory tract infection, constipation, and all factors that may increase intra-abdominal pressure should be avoided before surgery. Preoperative sit-up training is beneficial in increasing flap blood flow. Patients with a history of smoking should quit smoking for at least three months. A low residue diet should be given for one week before surgery, 1~2 units of blood should be prepared, fluids, rehydration, antibiotics should be given on the day before surgery, and clean enema should be given on the morning of surgery. Surgery Breast reconstruction is usually performed under general anesthesia or epidural anesthesia. The surgical procedure includes reconstruction of breast volume and shape, repair of skin defects and reconstruction of nipple areola. At present, the commonly used methods of breast reconstruction are as follows: 1, abdominal transverse rectus abdominis myocutaneous flap (TRAM) with tibial or free grafting: at the same time as breast reconstruction, abdominal wall plastic surgery, the donor area is hidden, which is one of the more commonly used methods with better results. 2, broad back muscle flap (TRAM) with tibial or free transplantation: in breast reconstruction at the same time as abdominal wall plastic surgery, hidden donor area, is one of the more common and effective methods. 2.Broad back muscle flap with tip transplantation combined with artificial breast prosthesis implantation. 3.Skin expansion and implantation of breast implant: skin expander is implanted first, and when the skin expands to a sufficient area in about two months, the expander is replaced by artificial breast implant. The reconstruction of nipple and areola is usually carried out half a year after the first stage of surgery. Postoperative precautions The drain is usually removed about two days after the operation, and the stitches are removed one to two weeks after the operation. Lower abdominal transverse rectus abdominis muscle flap breast reconstruction patients should be taken to bend the knees in a semi-recumbent position; fasting, bowel sounds recovered carefully given fluids; one day after the operation to remove the urinary catheter; to avoid the tip of the pressure and the flap near the overheating; abdominal elastic bandage, one day after the operation, you can get out of bed, but do not do the straight waist action, generally two weeks after the gradual extension of the flap, six weeks after the normal activities can be gradually.
