Chest ectropion, generally refers to rib ectropion, is a common malpresentation, mostly refers to the lower ribs turned outward, that is, the phenomenon that the lowest rib exceeds the outer edge of the body, which can be corrected by surgery. If children’s rib ectropion deformity, may be due to calcium deficiency or rickets, should be given timely calcium supplements, vitamin D3 oral and so on. The correction of children’s rib ectropion deformity should go to the pediatric surgery department of the regular hospital through the specialist physician’s examination, thorax positive and lateral radiographs and other examinations, to understand the degree of thoracic deformity for surgical correction and treatment, such as rib reversal surgery. Adults with more severe rib ectropion may affect cardiopulmonary function, leading to difficulty in voluntary breathing and may cause respiratory infections and other diseases. Sternal braces can be installed to support the ectropic ribs, and the ectropic ribs can be reshaped after 2 years. If the effect of the sternal brace is not good, surgery can be performed to give correction. Patients with thoracic ectopia are advised to go to the hospital in time for consultation and standardized treatment according to the doctor’s instruction after the cause of the disease is clarified.
