For modern women, breasts are not just for breastfeeding, but more often than not, full, firm and symmetrical breasts bring women physical charm and psychological confidence. People gradually believe that full and firm breasts are a unique symbol of female beauty and an important sign of female charm, which has become a fashionable pursuit for more and more women. However, when women reach a certain age or after giving birth, there will be different degrees of breast laxity and sagging, which will affect the curve of women’s body shape ……. The medical term is breast sagging. After breastfeeding, most of the women will have atrophy, laxity and different degree of sagging of both breasts, and some of them will have mild asymmetry of height. In this case, if you take simple breast augmentation, you can not solve the problem of sagging and asymmetry. If a breast lift is performed, the scarring caused by the surgery is unacceptable to most women. So what can be done to maintain a beautiful breast shape with minimal damage and no visible marks after healing? Based on this, under the premise of a large number of clinical practice and summarizing the experience of peers, for mild to moderate ptosis and asymmetric breasts, we adopted the dual-plane technique of breast augmentation based on breast implantation under direct visualization of the areola incision, gland folding internal elevation technique and gland misplaced adhesion technique to correct the breasts, and achieved simple, easy to perform, safe, and satisfactory clinical results. The procedure was performed using the lower areola approach, with no extra incisions and minimal operative damage. The dual-plane breast augmentation technique used is a technical guarantee that effectively reduces the occurrence of periosteal contracture, in addition to obtaining a better feel in a short period of time and giving the breasts a certain sense of movement. In addition, for patients with a certain breast volume and mild ptosis, the “gourd” deformity can be prevented in the long term. The dual-plane approach to breast augmentation takes into account the position of the implant in relation to the soft tissue coverage, combining the advantages of the inframammary plane and the infraspinatus plane, while avoiding the disadvantages of both to the maximum extent possible.
