With the change of people’s lifestyles, most children like to wear I-vests or low-cut clothes in the hot summer, whenever this time there will be some children very low self-esteem, the reason is mainly because some children’s sternum is abnormally protruding outward, that is, affecting the beauty of the body shape, but also cause psychological burden, causing different degrees of psychological disorders, and even become a lifelong pain for the child. Due to the deformity of the chest, children often lack self-confidence, are introverted and withdrawn, have a sense of inferiority, and are reluctant to participate in outdoor activities or social activities, and it is difficult to cover the protruding chest wall with clothing, and to cover the raised chest when sitting or walking, resulting in hunchback. There is a rumor on the Internet that calcium must be supplemented to treat chicken breast, can calcium really treat chicken breast? Myth: Chicken breast is caused by calcium deficiency. In fact, there is a misconception that chicken chest cannot be treated by calcium supplementation. Chicken chest is a common thoracic deformity, manifested as: the sternum protrudes outward abnormally, like the sternum of birds, which is also the origin of “chicken chest”. It is a common thoracic deformity, as is funnel chest. So what exactly is the cause of chicken chest? In the past, it was believed that the development of chicken chest was mostly related to calcium and phosphorus metabolism, mostly caused by malnutrition caused by insufficient calcium intake or absorption disorders, so many people take calcium supplementation treatment. However, with the continuous improvement of people’s living standard, malnourished children have become more and more rare, but the incidence of chicken chest has not significantly reduced, and many chicken chest children’s laboratory tests do not indicate calcium deficiency, and calcium supplementation treatment does not show obvious effects. Therefore, in recent years, most scholars believe that the main cause of funnel chest or chicken chest is the overgrowth of ribs and rib cartilage, with the elongated rib cartilage bulging forward to form a chicken chest and sunken backward to form a funnel chest. As the anterior and posterior diameter of the thorax increases and approaches the maximal inspiratory state, the respiratory motion amplitude is reduced and lung compliance decreases, resulting in increased residual air volume and decreased lung capacity and reduced lung function reserve. Some patients in this group will have reduced activity tolerance and varying degrees of respiratory symptoms, and some may have shortness of breath, weakness and chest discomfort after activity, all of which are associated with potential impairment of lung function. Chicken chest can not only cause physiological effects, but also cause different degrees of psychological disorders. Due to the deformity of the chest, patients often lack self-confidence, are introverted and withdrawn, have a sense of inferiority, and are reluctant to participate in outdoor activities or social activities, and it is difficult to cover the protruding chest wall with clothing, which causes hunchback when sitting or walking to cover the raised chest. Therefore, once a child is found to have a chicken chest, do not blindly take calcium supplements, parents should take their children to a regular hospital for medical consultation. For adolescent children, the appearance of the defect is sometimes even more important than the physical impact, so the psychological impact of chicken chest on children is more common. For children with obvious cosmetic deformities that have a psychological impact on the child, treatment should be prompt. Minimally invasive sternal sinker surgery is a better treatment method for chicken chest because of its simplicity, few complications, and both minimally invasive and aesthetic advantages.
