As the name implies, there are multiple breast developments, which are also known as multiple breast deformities in medicine. What are the causes of parastomastia? There are both congenital and acquired reasons for the occurrence of parametrium. The congenital factor is due to the fact that during embryonic development, the mammary gland development line from the armpit to the groin can develop into a breast. The pseudo-parametrium is caused by wearing tighter clothes that cause the local tissue to protrude, and over time the protruding tissue forms a mass; of course, it can also be caused by hormonal changes, as some women have hormonal changes in their bodies after having children, leading to the development of parametrium. What are the treatment methods for parastetals? Different treatment methods are available for different situations: 1. If the pseudo-parametrial breast is caused by improper dressing, it can be improved by correcting the dressing, and long-term local massage can also promote the fading of the pseudo-parametrial breast. 2, for the case of parametrial projection is not obvious, you can use the exercise of the upper arm and chest muscles to improve, this situation is generally not serious parametrial, exercise can make the slight enlargement of parametrial smaller. If the parametrial projection is obvious and seriously affects the beauty, it is necessary to take treatment, surgery is the most effective method, plastic surgery can be completed under local anesthesia, the incision is about 2-3 cm long, the surgery will be completely removed from the local parametrial subcutaneous glands, and then use cosmetic sutures, the post-operative scar is located in the armpit, not easy to find, and as long as the parametrial glands are removed, it will not recur.
