1. First of all, chicken breast is also called pigeon breast. The sternum bulges forward, which looks like the breast of a chicken or pigeon, so it is called chicken breast. It is a common thoracic deformity, with an incidence of about one in 4 people, which is more common in children, with more males than females, and the male: female ratio is 4: 1. Most of them occur before the development of 11 ~ 14 years old, and some of them are caused by unbalanced rapid growth in a short period of time. It is generally believed that they are related to heredity as funnel chest malformation, and about 2 ~ 25% of them have family history.
2. Secondly, it is generally believed that it is caused by the overgrowth of ribs and costal cartilage, and the deformity of sternum is secondary to the deformity of ribs. Pectus excavatum usually occurs alone, with few systemic abnormalities, but it is also one of the symptoms of other syndromes, such as Turner syndrome, Noonan syndrome, Marfan syndrome, Ehlers-Danlos syndrome, Morquio syndrome, triploid trisomy 18 and 21 syndrome, hypercystinuria, osteogenesis imperfecta and multiple nevus syndrome (Leopard syndrome). In addition to the mental burden and personality influence caused by the deformity, the chest wall deformity that affects the respiratory and circulatory functions also needs surgical correction.
3. Finally, there are many reasons for this deformity, which are not only related to congenital dysplasia, but also related to malnutrition in the later period. Moreover, diseases in the chest cavity may also cause chicken breasts. Attention should be paid to children's diet and disease prevention during childhood.
Precautions
Diseases of chicken breasts can be prevented, and nutrition should be paid attention to in the later stage of pregnancy, especially calcium supplementation. Babies should also pay attention to breastfeeding, take more vitamin D supplements and let their babies bask in the sun.
