Abstract
Throughout the history of surgery for pectus excavatum (PE), the Nuss procedure and open repair have been performed with many modifications, with most of these procedures using a metal bar. However, the use of a metal bar has several drawbacks. Thus, we aimed to develop a procedure that did not require a metal bar. Through our experience of 426 pediatric cases that underwent various procedures for open repair of PE at Nagoya City University, we arrived at the current procedure that we describe herein. We have evaluated this procedure by review of clinical results and deformity indices (Haller's, steepness, excavation volume, and asymmetry index). The latest and current procedure that supports the sternum with a bridge constructed by the 4th or 5th costal cartilages is associated with fewer complications, a lower re-operation rate, and striking improvement in the indices examined. Our current open-repair procedure that does not require a metal bar is recommended for correction of deformities of PE in children.
