If children have pectus carinatum and need treatment, it is necessary to check if the children's hospital has a specialized thoracic surgery department. If there is a pediatric thoracic surgery department, one can make an appointment there. Generally, for mild cases of pectus carinatum, children do not need surgery and can undergo conservative treatment, such as having a custom chest orthosis made. Wearing the chest orthosis can correct the condition. If the pectus carinatum is severe, and the child is over four years old, then surgery can be considered in the thoracic surgery department. Therefore, for pectus carinatum, appointments need to be made with the thoracic surgery department at a children's hospital.
