Pectus excavatum in children refers to abnormal development of the thorax with a long anterior and posterior diameter, mostly thought to be associated with overgrowth of the ribs and rib cartilage. The deformity of the sternum is secondary to the deformity of the rib cage and affects the respiratory circulation of the chest wall. Examples include pectus excavatum, funnel chest, pectoral cleft, etc. In addition to the mental burden and character effects caused by the deformity, the deformity itself is damaging to the respiratory and also circulatory system and needs to be corrected, so the pectus excavatum in children also needs to be treated. In terms of clinical manifestations, most pheochromocytomas are not easily detectable after birth and gradually become obvious after early childhood. The symptoms of compression of the heart usually rarely occur in pectus excavatum. In heavy cases, recurrent upper respiratory tract infections, or asthma, poor activity endurance, easy fatigue, and more importantly, the patient has a great mental burden due to the deformity.
