Nipple reduction surgery generally includes shortening of nipple length, narrowing of nipple thickness, correction of nipple drooping, and correction of nipple shape unsmooth and bilateral asymmetry. The operation was performed under local anesthesia. Incisions are formed on the circumference of the nipple base or the nipple cylinder to remove excessive nipple tissue, and then sutured. After operation, the stitches will be removed only after 7-8 days of gauze covering. The possible complications of operation include nipple numbness, unsatisfactory appearance, nipple necrosis and the possibility of affecting breastfeeding. Nipple reduction is a very delicate breast plastic surgery, which requires the surgeon to be very familiar with the knowledge of nipple vascular neuroanatomy and be patient and meticulous in operation, otherwise it may affect women's later life, especially unmarried women who are not pregnant.
