Many women will encounter some small embarrassment when dressing, both sides of the armpit always some fat exists, especially in the summer when these extra tissue nowhere to hide, some beautiful women will complain, “I have been very thin, but still very obvious”, some will seek to shape the bra to improve the shape, today we look at this is called Today we will see how the flab that is called “supernumerary” is a thing. The supernumerarybreast, also known as “polymastia”, as the name implies, is a redundant breast that has developed from the undegraded or incomplete mammary gland during the embryonic period and can occur in the armpit through the nipple to the original “breast line” of the groin. It can occur anywhere along the primitive “breast line” from the axilla to the groin. It occurs predominantly in women and occasionally in men. The incidence of parametrial breast in women is about 1-5%, and about 95% occurs in the axilla. The ectopic breast tissue is painful or swollen with the menstrual cycle, and behaves like a normal breast during pregnancy and lactation. Parametrium can develop benign or malignant tumors in the same area as the breast, and the glands of the parametrium are the histological basis for tumorigenesis. There is no conclusive evidence that ectopic breast tissue is more susceptible to malignancy than normal breast tissue, but it is important to observe changes in the parametrium during life. There are various ways to classify parametrial breasts, a more intuitive way is the Kajava classification scale, which divides them into eight categories, 1. intact breast (breast tissue, nipple and areola); 2. glandular tissue and nipple; 3. glandular tissue and areola; 4. glandular tissue only; 5. nipple areola with fatty areas but no breast tissue; 6. nipple only (polypoid); 7. areola only; 8. hair only Spot. In clinical practice, more attention is paid to the content of fatty tissue and breast tissue, which can guide the choice of surgical approach. Ultrasound of the breast is the most commonly used test for the diagnosis of parametrial breast. If the parametrial gland is accompanied by a tumor, needle aspiration biopsy, mammography and nuclear magnetic examination can clarify the diagnosis. For small parametrial glands with no obvious symptoms or with low requirements for appearance, no treatment can be done. When the following conditions occur, the parametrial glands should be removed: 1. For women, the surgery is to remove the ectopic nipple, areola and glandular tissue on the one hand, but more importantly, the scar is not obvious after the surgery to improve the appearance of bloating. To this end, plastic surgeons are constantly working on this goal. Currently, depending on the amount of fatty tissue and glandular tissue, fat aspiration, glandular excision, and a combination of both are selected, and incision locations are chosen to be as hidden as possible. And the incisions are cosmetically sutured to achieve a result that satisfies both the patient and the surgeon. Little TIP, the shape-shifting underwear may temporarily change the bloated appearance and make the breasts more upright and plump, but the tight bondage will lead to abnormal local hyperplasia, lymphatic reflux obstruction, and over time, breast hyperplasia, increasing local bulge with pain, and abnormal hyperplasia of breast tissue leading to the occurrence of parametrial cancer. Common doubts about surgery are as follows: 1. When is the right time to have surgery? Parametrial breast is more and more obvious after puberty with the change of menstrual cycle and breast development, so surgery is recommended after 18 years old. Please refer to the above for the specific indications for surgery. Just arrange your schedule, avoid your menstrual period, and make an appointment with your doctor in advance for the surgery. 2.Do you need to be hospitalized for the surgery? Depending on the way and size of the surgery, it is necessary to communicate with the surgeon in advance to decide whether to be hospitalized or not. 3.What kind of examination should be done before the surgery? Routine preoperative examination, such as blood routine, coagulation, biochemistry, chest X-ray, electrocardiogram, etc., in addition to ultrasound examination of the breast to exclude benign or malignant tumor of the breast. 4.Is the surgery under local or general anesthesia? The surgery is performed under local anesthesia, and general anesthesia is generally not required. 5.Does it hurt during and after surgery? Can you tolerate it? There will be some pain during local infiltration anesthesia, but there will be no pain during the operation, and mild pain after the operation. 6.What do you need to pay attention to after the operation? After the operation, you need to put pressure on the bandage and reduce the activity to avoid the occurrence of hematoma. 7.Does the surgery have risks? Any surgery has certain risks, the incidence of seroma and hematoma, flap necrosis, etc. is low. 8.Is the scar obvious? The incision is chosen in a hidden area, plastic surgery for cosmetic suturing, regular anti-scar treatment after surgery, the scar is not obvious.
