1, the cause of nipple invagination
1. Primary inverted nipple
(1) Smooth muscle dysplasia. The nipple has 15-20 openings of mammary duct, smooth muscle fibers are around the mammary duct, and the nipple is pulled inward by the muscle fiber bundles around the mammary duct and inserted into the nipple dermis. The texture of these muscle bundles is obviously different from that of mammary ducts.
(2) Lactic duct hypoplasia. The hypoplastic mammary duct failed to be ducted and showed a cord shape.
(3) Lack of supporting tissue under nipple.
2. Secondary nipple invagination
(1) is caused by disease. It is caused by the contraction of invading ducts, ligaments and fascia.
(2) Malignant tumor of breast. If a woman with normal breasts has nipple invagination without obvious reasons, mammography should be performed to check whether there is breast malignant tumor.
(3) breast surgery. When using dermal pedicle in breast plastic surgery, tension and scar contraction can also cause nipple invagination.
3. Other common reasons
(1) The clothes are too tight. If women's underwear is too tight during chest development, it is easy to cause nipple depression.
(2) Improper use of bra. If the bra is too small, too tight or used too early, it will cause nipple depression.
(3) It is related to heredity. Clinical observation: In the generation of mothers and their mothers, those whose grandmothers have a history of nipple depression are more likely to suffer from nipple depression in the next generation than normal people.
2. Symptoms of nipple invagination
1. Main manifestations of nipple invagination
One or both sides of the nipple are hidden under the skin of the breast. If there is periductal mastitis, the patient may have erythema or pain around the areola, and there will be a lump under the areola; If it is nipple invagination caused by breast cancer, the patient's breast may have skin diseases such as orange peel and nail.
2. A variety of people with inverted nipples
Primary nipple inversion mostly occurs in adolescent girls, while secondary nipple inversion is more common in lactating women. Because of mammary duct ectasia or periductal mastitis, breast tumors will be accompanied by breast masses and corresponding skin lesions.
3. Complications caused by nipple invagination
(1) local infection. Nipple invagination makes local cleaning difficult, and it is easy to cause infection and chronic complications, and local exudates will accumulate, and some even have symptoms such as stench and skin erosion.
(2) Breastfeeding is difficult. Due to nipple invagination, local uncleanness, milk deposition, secondary infection and even acute mastitis can be caused.
(3) affect the appearance. Nipple invagination will affect the beauty of women and need plastic surgery.
3. Preventive measures
First, any female in immediate family members, such as mother and nipple invagination during menstrual period, should be taken as the key prevention targets. After the birth of a baby girl with genetic tendency, the mother can gently pull the nipple outward, 1-2 times a day. Pay attention to the action must be gentle, it is best to ask experienced people to operate. In this way, we can see that the baby's nipple is mung bean-shaped or small round and higher than the skin, and the probability of nipple invagination is greatly reduced.
Second, pay attention to clothes. Close-fitting underwear should be made of cotton, changed frequently and exposed to more sun. If the nipple shows signs of redness and cracking, the underwear should be cooked and disinfected, and it is not too early for girls to use bras.
Third, prevent extrusion. Underwear and bra should be suitable, not too tight. For girls with big breasts, more attention should be paid to the looseness of breasts. For girls who have prone habits, it is necessary to correct them in time to prevent nipples from being squeezed, so as not to aggravate the degree of nipple invagination.
Fourth, pregnant women with inverted nipples should pay special attention to the health care and hygiene of nipples after delivery. Hangzhou nipple invagination correction experts said that if the nipple is slightly depressed, the number of sucking of the baby should be appropriately increased, and at the same time, attention should be paid to protecting the nipple, cleaning after breastfeeding, and beware of infection. Once the nipple is red and swollen, you should go to the hospital for examination in time to prevent mastitis.
