Nipples are a very important part of women's breasts. Nipple invagination will not only affect the beauty of breasts, but also affect health and breastfeeding. Therefore, it is best to reshape the nipple through nipple inversion correction surgery in time to make the breast more perfect! According to experts, nipple invagination can be divided into three categories: first, some nipples are invaginated, and the nipple neck exists and can be easily squeezed out. After extrusion, the nipple size is similar to that of ordinary people. Second, the nipple is completely sunken in the areola, but it can be squeezed out by hand. The nipple is smaller than normal, and most of them have no nipple neck. The third type is that the nipple is completely buried under the areola, and the invaginated nipple cannot be squeezed out. So, how to correct nipple invagination? The treatment of nipple invagination is generally based on corrective surgery. Primary nipple (congenital) invagination can be treated conservatively first. For example, the nipple is sucked under negative pressure with a breast pump, or pulled by hand. In severe cases, those with ineffective traction should be treated by surgery. Secondary nipple invagination is often caused by breast cancer and should be diagnosed first. The invagination caused by inflammation, trauma and surgical scar should be treated with corresponding etiology and plastic surgery in the later stage. The operation is mainly to cut off and loosen the fiber bundle pulling the nipple, cut off some nonfunctional shortened mammary duct when necessary, and fill local mammary tissue as the supporting tissue of the nipple; Local tissue was used for nipple reconstruction. The nipple invagination correction operation can make the nipple invagination correct and protrude on the breast surface, improve the appearance, leave no scars on the nipple and areola (the surgical traces in the above areas are not obvious due to nipple pigmentation in areola), and improve the breastfeeding function.
