Summer is almost here again, this is the most favorite season for young girls, sun, beach, waves, girls and bikini …… these are always closely linked to the summer, they can wear beautiful clothes and skirts, free to show their beautiful body. Every now and then, a few girlfriends together shopping and dressing themselves, is also a very pleasant thing. ”Jing Jing, this weekend XX mall women’s clothing sale, we go together to see it. And, this year’s swimwear I have not yet purchased, it is said that there are also a lot of new it.” Beijing Union Hospital Plastic Surgery Department Wang Xiaojun “No, I still have some things to do at home this weekend, you guys go shopping.” ”You’re always like this, then we’re leaving, oh, bye.” ”Bye, buy back new clothes to show me well oh.” After sending off her friends in the same room, Jing Jing’s smiling face immediately dulled down, so many years, I do not know how many times, Jing Jing reluctant to go shopping with her friends, because the clothes suitable for their own wear is too little. Watching them confidently in the fitting room in front of the dressing mirror to take a look around, but she always as a companion, over time, T-shirts became her unchanging “uniform”. This is all because her breasts are too big, every summer has become a lingering worry for her. Since middle school, her breasts have developed faster than others, and the “size” is much larger than others. Gradually, she could not stand the strange stares of her classmates around her, and some naughty male classmates privately called her “bosom”, she was too shy to participate in group activities, reluctant to go to physical education classes, so she was also fatter than other girls, which added to her low self-esteem. Because of her breasts, she was even more afraid to go near swimming pools and public baths. The large breasts not only brought her psychological inferiority, but also brought her a lot of physical problems. First of all, it was difficult for her to buy a suitable bra, and the weight of her breasts made her shoulders and back heavy and uncomfortable, and she often felt painful, so she often had to hold her chest and arch her back; secondly, it was inevitable that her breasts would sag, and the lower crease of her breasts would feel very hot in summer, and she would sweat more and compost there, so she often had heat rash and skin erosion, and over time there would be sweat stains and pigmentation, which made Jingjing very distressed. It is very distressing for Jingjing. For her, summer is the season she dislikes the most. I believe that many girls are also troubled by the discomfort caused by huge breasts, just like Jing Jing. As the second sexual characteristic of women, breasts have the physiological function of nurturing offspring and also exist as a sexual organ in gender interactions, so their shape and beauty are especially important. The shape and size of the breast varies from person to person and is related to age, pregnancy and other factors. Oversized breasts are out of proportion to the body, making the breasts lose their beauty, and due to the pull of gravity on the breasts, large breasts are more or less accompanied by breast sagging, the areola also becomes larger, losing the ability to retract under gravity, the sensory nerves are stretched, and the sensitivity of the nipples is reduced. For oriental people 250~350ml of breast is appropriate, more than 500ml is considered as breast enlargement. A single breast of more than 1500 ml is called mega-breast. The causes of breast enlargement are not well understood and are related to genetics, endocrine and other factors. It is thought to be related to the increased sensitivity of estrogen receptors on breast tissue cells, since most patients with gigantomastia have breast enlargement. The psychological and physiological burden of breast enlargement is obvious, so plastic surgery is needed to reduce the size of the breasts and to solve their distress. Since ancient times, large breasts have been a symbol of femininity and fertility in both the East and the West, and women with oversized breasts are often looked at differently and their femininity becomes a deformity. As a result, surgery to reduce the size of oversized breasts and shape them into a normal shape has been explored for centuries. The first true breast reduction probably occurred in 1669, performed by the English physician William Dwiston, and has since been explored and developed by countless others, resulting in the current horizontal bicuspid flap, vertical bicuspid flap, Pitanguy method, and many other procedures. However, the results are not good enough, the shape of the breast is not natural, and most importantly, the scar of the surgical incision is too obvious and not suitable for oriental people. At the same time, it takes the nipple-areola complex as the center and shapes the breast as a whole, treating the skin and glandular tissue as two independent anatomical units, without worrying about the nipple-areola complex It is especially suitable for oriental people who do not have large breast size. Based on the anatomical research and the characteristics of Oriental people and previous literature, the plastic surgery department of Peking Union Medical College Hospital has gradually developed the technique of “Union Plastic Surgery”, which uses different treatment plans according to the situation of different patients. If there are not many breast glands and redundant skin to be removed, the simple “double ring method” can be used to correct breast enlargement, and the “skin bra” and “dermal bra” formed by the surgery can The “skin bra” and “dermal bra” created by the surgery can further ensure reliable results. If the sagging of the breast is significant, it means that the suspension system of the breast has been significantly damaged and the main goal of the surgery is to reposition the nipple and rebuild the suspension system. This method has been reported since 1981 and is equivalent to placing a breast shield inside the skin to support the breast, with excellent long-term results. If the breast volume is very large and the basal transverse diameter of the breast is also large, the surgery should remove the outer skin in addition to the excess gland and reduce the transverse diameter of the breast, which can achieve satisfactory results by combining the above techniques. In addition, the additional incision on the lateral side of the breast enables the incision scar to be hidden within the bra, so that normal dressing, swimming and sports are not affected, ensuring maximum aesthetics. With the encouragement of her friends, Jing Jing bravely went into the plastic surgery office and confided her worries to the doctor, who chose the most suitable procedure for her and performed the breast reduction surgery. With the doctor’s help, Jingjing finally got out of the shadow of the “T-shirt girl” and became more cheerful and confident, and she is already looking forward to the next summer.
