When the nipple of an adult woman is trapped under the skin surface of the areola and does not protrude out of the areola plane, resulting in local mouth shape, it is called nipple invagination. The degree of nipple invagination varies, some only show nipple invagination, and the most serious performance is nipple depression or even inversion. Nipple invagination not only hinders the beauty of the breast, but also hinders the lactation function, and it is difficult to clean locally. The concave part is easy to hide dirt and accept dirt, which often causes local infection. The mammary duct is connected with the concave part, and inflammation can spread into the breast, causing mastitis, which should be corrected.

Nipple invagination is mainly congenital, but it can also be caused by trauma or surgery, breast tumor and fibroplasia after mastitis. The main cause of congenital nipple invagination is the dysplasia of smooth muscle of nipple and areola. These muscle fibers are pulled inward, and the lack of supporting tissue under the nipple forms nipple invagination. Entrapment usually occurs on both sides at the same time or unilaterally. The inverted nipple can come back as long as it is squeezed or pulled slightly, which belongs to mild nipple inversion, also known as reversible nipple inversion. This kind of nipple invagination can be corrected by non-surgical conservative treatment, and the best time for treatment is before marriage or early pregnancy. Specific methods include manual traction and instrument traction.

Hand traction: squeeze the nipple out of the skin surface by yourself, hold the nipple horizontally or vertically with your thumb and forefinger, and pull the nipple outward continuously or intermittently for about 30 minutes each time, alternating sides. 3-5 times a day. Instrument traction: that is, using the negative pressure principle to suck out the nipple with a manual or electric breast pump, or sucking out the nipple continuously or intermittently, 30 minutes each time, alternating on both sides, 3-5 times a day. After two months, the above two correction methods can get good results.

Irreversible nipple inversion, that is, severe nipple inversion, can only be corrected by surgery. The operation is to completely loosen the invaginated muscle fiber bundle and fill the surrounding tissue under the nipple, so as to enhance the supporting force of the nipple and make the nipple bulge and plastic. Surgery is generally performed under local anesthesia, and there are various surgical methods, which can be selected purposefully according to specific conditions. The operation is carried out in the areola, which is small and will not leave obvious surgical scars. Under normal circumstances, it will not damage the sensory nerve of the nipple, so it will not hinder the normal feeling of the nipple after operation. Surgery generally does not destroy the mammary duct, so it will not cause breastfeeding disorders.

It is worth mentioning that after surgical correction of inverted nipple, there is still the possibility of recurrence. Therefore, 5-7 days after surgical suture removal, it is necessary to manually pull the nipple for 1-2 months, and if conditions permit, it can also be pulled with instruments to consolidate the curative effect and prevent the recurrence of nipple invagination. Is it the same as above, but different? Let's go to the hospital to find out more about it.
