The authors have studied the result of 34 pectus excavatum, corrected by two surgical methods, followed up between 3 and 20 years: half of cases were treated by Judet's procedure, making turn over of anterior wall chest, with 35 per cent of good result. The other cases were treated by sternochondroplasty and internal fixation, with 88 per cent of good result. Early failures related to sternal non union and to infection, occurred in 53 per cent of Judet's procedure; eight of the 13 failures were managed by sternochondroplasty (7 cases) and Judet's procedure (1 case); followed by good results. Failure at further time was related to the young age of the patients at treatment, to the deficiency of fixation and early removal of material. Consequently, durable correction at long term was obtained, when treatment was performed by sternochondroplasty procedure, over 14 years of age, when many pins were used for fixing the correction, left in place for more than one year. In such cases, we didn't observe regression of result. When small residual deformities subsisted they were often masked by the development of the muscles in man, and breast in woman, providing acceptable aspect of chest.
