Funnel chest

The funnel chest is a congenital and often familial disease. Males are more common than females, and it has been reported that the male to female ratio is 4: 1, which is associated with dominant inheritance. It is mainly manifested as sternum, rib cartilage, and some ribs in the middle of the anterior chest of the child. At the lowest point, a boat-like or funnel-like deformity is formed, which causes the organs in the chest cavity to be oppressed or even displaced, and causes children's heart and lung development and function to be seriously affected.
