Normal women's nipples are uniform and cylindrical, the thickness is proportional to areola and breast, and both sides stand forward symmetrically, which is full of beauty. (But the nipple is too long and thick, losing its normal proportion or even drooping, and its appearance is not beautiful. Women are beginning to worry about this, which can be changed by simple nipple reduction. Nipple reduction surgery generally includes nipple length shortening, nipple thickness narrowing, nipple drooping correction, nipple shape unsmooth and bilateral asymmetry correction. 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. For women with large nipples, the nipple diameter is 6 ~ 8 mm and the height is 7 ~ 9 mm If the nipple exceeds this range, the nipple is too large. The main reason is genetic factors or nipple sensitivity to stimulation. Nipples are too large to be primary, which is more common in unmarried women; It may also be caused by children sucking and pulling. If the nipple is too large and too long, annular, semi-annular, V-shaped and partial excision can be used. Cosmetic nipple reduction avoids damaging mammary ducts and nerves, and completely restores the "touch" feeling of nipples without leaving traces.
