During 22 years from 1959 to 1981, 422 sternal turnover operation for funnel chest have been experienced. A couple of technical modification have been developed. 1. High transsection of sternum is done, preferably at first or second intercostal space. 2. When either side of rib is transsected, attempt is made to leave posterior portion of periostium in the anterior mediastinum. Turned over sternum is placed on this remaining perostium, which is expected to promote bone union. 3. The sternum is turned over at 180 degree with rectus abdominal muscle attached to xyphoid process, which is expected to maintain blood supply.-Pedicle sternal turnover-this technique can be done without affecting the merit of standard sternal turnover operation. At least there is no demerit in employing this technique. 4. From cosmetic stand point, transverse skin incision is made for those of which deformity configuration is localized mainly in central and lower portion of sternum.
