Traditional prosthetic breast augmentation surgery needs to make a small incision in the armpit, inframammary fold or areola, then put in the pre-selected breast prosthesis, adjust the position and shape, suture the wound, and remove the stitches after the wound heals. You usually need to rest for 5-7 days. Methods: 1. According to the surgical incision, it is generally divided into axillary top incision, anterior axillary incision, areola incision and inframammary fold incision. 2. According to the implantation level of the prosthesis, it is divided into two levels: posterior gland and posterior pectoralis major. 3. Axillary top incision and posterior layer of pectoralis major muscle are generally used, because the incision is hidden and feels natural, and capsular contracture is not easy to occur.
