Treatment should be decided based on the specific condition of the child's pigeon chest. For mild to moderate pigeon chest, especially in children, where there is no compression on the heart and lungs, conservative treatment should generally be considered. The best method for correction is to pay attention to posture and engage in appropriate physical exercise. Additionally, a thoracic orthotic can be used; the effects of wearing a thoracic orthotic for correcting mild to moderate pigeon chest are generally quite positive. For severe pigeon chest, particularly when there is compression affecting the heart and lungs and thus impacting cardiac and pulmonary function, surgical treatment should be considered to correct the severe pigeon chest.
