title: [X-ray analysis of 114 cases of harelip and clinical evaluation of infants' thymus].
abstract: The authors classify the thymic image on the pre-operative chest films of 114 cases of harelip babies under 2 years of age into 5 types and divide the size of thymus according to the cardiothymic thoracic ratio (CT/T) into 4 classes. The thymic prominence rate is 93.9%. There is marked variability in the size and shape of thymus, no definite normal standard could be found. In 6 preoperative cases, stress involution and regeneration induced by the administration of steroids has been observed. Whether or not the normally large thymus found on the chest film in baby-hood influence the safety of operation was discussed.
