Children often have paradoxical breathing, cyanosis, dyspnea and recurrent respiratory infections. Physical examination reveals soft tissue fissures in the upper, lower, or all of the sternal region and palpable vascular pulsations.Cantrell’s syndrome is also characterized by central line defects in the upper abdominal wall, pericardial defects adjacent to the diaphragm, and various types of cardiac malformations. The diagnosis is confirmed by the physical examination of the child based on the clinical presentation and the finding of a soft tissue fissure in the sternal region. Thoracic deformity in children snoring during sleep narrows the airway and increases the resistance to breathing, so they inhale hard and pull the thorax hard. At this time, the child is in the period of growth and development, the bones are relatively soft, long-term this will easily lead to thoracic deformation. Infants and young children because of the rapid growth rate and the need for calcium, at the same time, outdoor activities are less, it is easy to occur calcium deficiency. Calcium deficiency in children can cause rickets. Thoracic collapse deformity is common in funnel chest. Signs of funnel chest, the sternal body (especially the root of the raphe) and its corresponding sides of the 3rd to 6th rib cartilage inward, resulting in the anterior chest wall resembling a funnel, and the heart is displaced by pressure. Sternocleidomastoid fissure occurs when there are obstacles in the process of mutual healing of sternocleidomastoid cords during embryonic period, and clinically it can be manifested as total or partial absence of sternocleidomastoid bone, hemilaminar absence, and window shaped defects. Sternocleidomastoid fracture is the most common, and its site can be seen in the upper thoracic segment, the lower thoracic segment, or the full length of the sternum.
