Congenital nipple inversion is divided into three degrees, and the treatments are also different, mainly as follows: 1, patients with degree I who are in puberty can be simply manipulated to reset, such as patients can lift the nipple outward several times a day with their hands, and if the patients with degree I are over 20 years old, nipple braces can be used to correct them; 2, if patients with degree II are in puberty, manipulation can be used to reset the nipple, and if the patients with degree II are 20 years old or over 30 years old, it is recommended to apply nipple braces; 3, patients with degree III who are in puberty can try to correct them with nipple braces, but the vast majority of patients with degree III need to receive surgery. If the patient of degree II is already 20 or 30 years old, it is recommended to apply the nipple aligner; 3. If the patient of degree III is in puberty, it can try to use the nipple aligner to correct it, but most of the patients of degree III need to undergo the surgical treatment. It should be emphasized that the current surgical treatment both corrects the shape of the nipple and at the same time ensures the function of breastfeeding of the nipple. Patients with nipple inversion at special times, such as during breastfeeding or pregnancy, should go to a specialized clinic for consultation, and a professional doctor will weigh the pros and cons and formulate a specific treatment plan.
