Regarding the registration of patients or children with pectus excavatum, if it is for children and the consultation is only about the hereditary aspect of pectus excavatum or its etiology, consider registering at the pediatrics or child health department. It is also feasible to consult the genetics department. If the consultation is about treatment options for pectus excavatum, including methods of treatment, consider registering at the thoracic surgery department. Thoracic surgery can provide advice and methods for the treatment of pectus excavatum, including both surgical and non-surgical options. Of course, not all hospitals have a thoracic surgery department; generally, municipal third-level, first-class hospitals are equipped with thoracic surgery departments. If there is no thoracic surgery available, consider registering under the general surgery department.
