The pectus excavatum or funnel shaped thorax is a relatively frequent malformation of the chest wall which composed of depressed sternum and costal cartilage. The so-called sternal turnover operation for pectus excavatum has been disappointing due to postoperative complication such as fistula formation with necrosis of bone and muscle. Thus, the need of preserved vascular pedicle to sternum was stressed in this type of operation, keeping the bilateral internal mammary vessels preserved. We have experienced two cases of modified sternal turnover in children and obtained satisfactory postoperative results.
