Do you have to lose your breasts if you have breast cancer? No! At present, breast reconstruction technology after radical breast cancer surgery is relatively mature, and breast reconstruction can be performed after breast cancer surgery. Breast reconstruction can restore (or restore) the original volume and shape of the breast to the maximum extent possible, and to achieve proportionality with the opposite breast, or even to create larger and more beautiful breasts, thus returning women’s body shape to perfection, which is very helpful to restore self-confidence and improve the quality of life. There are various surgical procedures for breast reconstruction, and different surgical procedures have different indications. The surgeon should choose a suitable surgical procedure according to the patient’s requirements, taking into account her physical, psychological and economic conditions. Breast reconstruction can be divided into three categories according to different reconstruction materials: 1, breast reconstruction with implants, mainly silicone gel implants; 2, breast reconstruction with autologous tissues, mainly with rectus abdominis muscle flap, latissimus dorsi muscle flap and other autologous tissues; 3, combined reconstruction with autologous tissues and prosthesis, of which combined reconstruction with latissimus dorsi muscle flap and prosthesis is the most common. The specific surgical procedures commonly used for breast reconstruction after mastectomy are simply breast reconstruction with implants, which often do not provide sufficient local soft tissue coverage, limited size of the reconstructed breast prosthesis, risk of prosthesis exposure, inability to present softness and proper sagging, and the effect of the reconstructed breast can be affected if radiotherapy must be received after surgery. Breast reconstruction surgery should minimize the surgical incision, reduce secondary trauma, and avoid complications in order to reduce patients’ surgical concerns and increase their acceptance of reconstructive surgery. Therefore, the trend of minimally invasive breast reconstruction surgery is an inevitable one. The Breast Reconstruction Group of the Department of Plastic and Reconstructive Surgery of North Medical College has reorganized the traditional breast reconstruction methods and established a relatively minimally invasive method as follows: dilator tissue expansion + endoscopic assisted small incision of latissimus dorsi muscle flap transfer + silicone implant placement Features: The overlying skin tissue is expanded with a dilator, and then a portion of the latissimus dorsi muscle is removed through an axillary incision or lateral thoracic incision (using a radical breast cancer surgery incision) with the assistance of an endoscopic system. A portion of the latissimus dorsi muscle is removed through an axillary incision or lateral thoracic incision (using a radical breast cancer surgery incision) and transferred to the front of the chest to increase the thickness of the encapsulated tissue of the prosthesis, and then a small prosthesis is placed to increase the volume of the reconstructed breast, thus forming a new breast organ. Compared with the traditional method, this method: 1. reduces the length of the incision to obtain a myocutaneous flap, avoiding a long incision scar on the back. 2. uses an expander to expand the breast skin tissue, avoiding the transfer of skin from other parts of the body to form a “patch” on the front of the chest and making the color and texture of the skin on the front of the chest consistent, with a better appearance. 3. continues the autologous 3. It continues the advantages of autologous tissue transplantation combined with breast implantation, and further reduces trauma to avoid obvious scarring (behind and in front of the chest) on the premise of obtaining good reconstructive effect, which is more acceptable to patients.
