1. Manual traction: Puberty is the breast An important period of development and also an important period to correct nipple inversion. Frequent stretching of the nipple can cause the nipple, breast ducts, fiber cords and smooth muscles to stretch and lengthen, and the nipple will naturally gradually bulge outward. But it takes a long time and is done step by step to achieve good results.

2. Suction therapy: The principle of suction therapy is similar to that of manual traction. The negative pressure suction device is used to pull the inverted nipple to achieve the purpose of lengthening the breast ducts and fiber cords.

3. Surgical treatment: (1) Nipple correction using the bracket method. So far, this method is the only surgical method that can preserve the breastfeeding function. The sunken nipple is fixed to an external bracket through a steel wire. Continuous stretching for 3 to 6 months can achieve the purpose of lengthening the nipple and correcting the inverted nipple. Suitable for patients with mild, moderate and severe depression. This method does not require making incisions in the skin, does not damage the breast ducts, can retain the breastfeeding function, does not affect the feeling of the nipple, and has a low recurrence rate. The disadvantage is that the treatment time is longer and may cause inconvenience to life. (2) Incisional nipple correction surgery can be used for women who have given birth and do not consider breastfeeding in the future, or for patients with recurrent local inflammation and serious sunken deformities due to scar traction. During the operation, the breast ducts are completely cut off, the sunken nipple is fully released, and a tissue flap is designed to fill the tissue defect at the root of the nipple to strengthen the support of the nipple. Inverted nipple correction by incision can be completed in one stage and the treatment time is short. However, the incision method requires severing or partially severing the breast ducts, which affects the postoperative breastfeeding function; if contracture occurs in the scar deep on the nipple, it will cause the recurrence of nipple inversion.
