The purpose of this study is to analyze the early results by the operative methods in 36 patients with pectus excavatum during the period August 1989 to August 1993. We underwent Ravitch`s operation in 15 patients [mean age : 11.0], which consists of subperichondral resection of all deformed cartilages, anterior wedge osteotomy and fixation in place with wire sutures of the sternum, and sternal eversion operation in 21 patients[mean age : 5.3], which consists of en-bloc resection of deformed sternum and cartilages, tailoring of the costal cartilages and shaping of the sternum and fixation of sternum and cartilages. Early results were satisfactory in 93% [Excellent 93%] for Ravitch`s operations and in 100% [Excellent 90% and Good 10%] for sternal eversion operations. But late results by sternal growth will be necessary longer follow-up.
