A firm breast is the focus of a woman’s beauty, and the nipple is the “delicate point” of the focus. The nipple is sunken into the areola, and in the milder cases, the nipple loses its projection, and in the more severe cases, it is completely sunken under the areola plane, showing a crater-like deformity. The reason for this is shortened milk ducts, poorly developed muscles in the nipple, less fibromuscular tissue under the nipple, empty tissue under the nipple, lack of supporting tissue, and shortened fiber bundles filling the milk ducts. There are more than a dozen types of surgical correction, some prone to recurrence and some with significant scarring, here are a few methods that are described without surgery. Manual pulling. The teenage period is an important time for breast development and for correcting nipple invagination. The nipples are often pulled to make the breasts stand out and to increase the support of the surrounding skin, playing a “shaping” role. Several times a day, over time, the nipples will gradually bulge outward. If you can’t pull, you can push the skin of your breasts near the nipples outward first. Suction therapy. After pregnancy, apply suction to the nipple several times a day, using its negative pressure to encourage nipple bulging. Nipple Corrector. This is the method the author focuses on. For mild, moderate and severe nipple invagination of various degrees, use a 10 or 20 ml syringe, remove the inner core, cut about 5 cm syringe, cut the end at 0, 3, 6, 9 points to pierce a 1 mm diameter needle hole spare. After local injection of a small amount of anesthetic, the suture is drawn out of the nipple, 20 ml syringe needle from the base of the nipple deep puncture to export two wires, crossed vertically in the shape of a cross, will be led out of the syringe, the base of the syringe set in the nipple has been raised, the wire from the needle hole in the syringe, the two adjacent twisted together, the wire end downward bend, to prevent scratching, every two months tightening, continuous traction for 3-6 months. This method is simple and easy to use, no incision is needed, the principle is to give continuous traction, because the time is longer, so it is not easy to recur.
