The small size of the breasts due to congenital or breastfeeding reasons is called hypo-breast volume, which is characterized by flattening or lack of augmentation of the breasts and a flat appearance of the breasts. This condition is a source of distress for many women. They want to have a pair of full and firm breasts to build up their self-confidence as a proud woman. Some women have resorted to wearing various bras with different ingredients and using various breast enhancement medications to stimulate breast growth, but the results are not satisfactory and may lead to physiological disorders. Many of them turn to plastic surgeons for surgery to restore the brightness of their breasts. Breast augmentation is a surgical procedure to increase the size of the breasts through the implantation of artificial breast implants or autologous fat injection grafts. Breast augmentation surgery has been performed for nearly 40 years in the world. It has also been performed in China for nearly 30 years. It is a relatively mature surgical method. Artificial Breast Implants Artificial breast implants are suitable for almost all patients who require breast augmentation. The incision is usually chosen in a more concealed area, and there are three commonly used incisions: ① axillary incision; ② areolar incision; ③ inframammary fold incision. Among them, the axillary incision is the most concealed and is generally difficult to be discovered by others after surgery. The incision is about 3 – 4 cm, and the surgeon forms a gap in the deep surface of the pectoralis major muscle and places an artificial breast implant of appropriate size. The advantages are: realistic appearance and excellent feel after surgery, the possibility of choosing breast implants of different sizes and shapes to meet the patient’s wishes, short operation time and cycle, and immediate results.
