Generally speaking, mild thoracic deformity has little effect on human physiological function, so preventive measures should be taken to prevent its further development. If the chest deformity is serious, especially the funnel-shaped chest, the heart and lung organs of the chest are compressed to varying degrees, and even the heart is displaced, and the lung ventilation function is also affected. If it develops further, it is prone to serious diseases such as respiratory tract infection. Pectus excavatum and chicken breast were diagnosed by chest examination. In order to determine the indication of surgical treatment, necessary chest X-ray examination and determination of heart and brain function should be carried out.

Chicken breast is also called pigeon breast. The sternum protrudes forward and looks like the breasts of chickens and pigeons, so it is called chicken breast. It is the second most common thoracic deformity in the anterior chest wall, which is less common than funnel chest. The incidence rate is about one thousandth, and the ratio of male to female is about 4: 1, accounting for 16.7% of all chest wall malformations. Symptoms appeared later, and more than 50% were 165438. The etiology is not clear, and it may be related to heredity, and the family history is about 20% ~ 25%. It is generally believed that the growth of ribs and costal cartilage is caused. Sternal malformation is secondary to rib malformation and can also be secondary to thoracic diseases.
