Inverted nipples are often overlooked in developing women. However, it is not known that nipple invagination is also a disease. It is a relatively common deformity. In congenital cases, genetic factors play an important role, and when the breast ducts and nipple muscles develop abnormally, it can lead to nipple invagination. In acquired nipple invagination, infectious factors are one of the main factors of their nipple invagination. There are three main effects of nipple invagination on women: 1. It affects the overall beauty and three-dimensionality of the breast. 2, breastfeeding: affects the breastfeeding function of unmarried or married people who have not had children. 3, the accumulation of dirt in the inverted nipple is prone to infection. For the treatment of invagination there are many methods, the lighter ones can be corrected through non-surgical treatment, but most patients seen in the clinic must be operated to achieve satisfactory results. The procedure is simple and can be done in an outpatient operating room under local anesthesia, but the choice of the specific method depends on the individual. For unmarried patients or those who wish to breastfeed in the future, it is preferred to choose a procedure that preserves the milk ducts in consideration of postoperative breast function. For patients with nipple invagination whose breast ducts are not seriously stretched, local flaps can be designed during surgery and bluntly separated from submammary duct adhesions to correct the invaginated nipples, such as purse-string nippleplasty, pike incision nippleplasty, areolar quadrangular star incision nipple invagination correction, areolar skin rhombic excision method, and small triangular areolar skin excision method. This method can be completed in one surgery. For patients who do not need to retain the function of breastfeeding, the crescent-shaped areola flap correction method and nipple dissection method can be used to completely cut off the fiber bundle between the breast ducts below the nipple to reset the invaginated nipple. This method has a low recurrence rate and is more suitable for patients with severe nipple invagination.
