Inverted nipple is a condition where the nipple is too short or it is trapped under the areola and cannot be pulled out by squeezing, traction, etc. It is called nipple invagination. If a patient has an inverted nipple, the first step is to determine if the nipple is truly inverted. The so-called true invagination is when you can’t pull or squeeze the areola to pull out the invaginated nipple, so it is called true nipple invagination. The indications for surgery are twofold: 1) the inverted nipple is not beautiful enough; 2) the surgery can be done in order to achieve smooth breastfeeding in the future. If you have mild nipple invagination, it can be partially improved by traction of the nipple for a period of time, including the secondary development of the breast during pregnancy, including the sucking of the nipple by the baby during breastfeeding, which can correct the nipple invagination. In the case of very severe nipple invagination, surgery may be required to correct it. Braces go only for relatively mild nipple shortening, or mild invagination, which can be corrected to some extent by continuous suction with negative pressure. But more serious invaginations are difficult to cure with orthotics. The reason for this is that the infant is able to massage the areola into his mouth through the negative pressure, so that he is able to feed the baby. But particularly serious nipple invagination may require some auxiliary means to achieve breastfeeding, such as using a breast shield, or using a breast pump to milk it out to feed.
