We designed the cross-bar technique to achieve remodeling of the entire chest wall. This study aimed to demonstrate the role of cross-bar and its benefits over the parallel bar.<\/jats:p><jats:p>\n          Materials and Methods\u2003The cross-bar technique involves placing two bars diagonally and then cross on the target. The primary purposes are to double the lifting forces by making two bars converge on a single target to lift inflexible heavy chest wall depressions or cover lower lateral areas. The results of the cross-bar and parallel bar are compared for the indications, postrepair outcomes, and complications.<\/jats:p><jats:p>\n          Results\u2003From 2016 to 2019, 247 patients who underwent multiple bar pectus excavatum (PE) repair were enrolled in the study: 157 with cross-bar and 90 with parallel bar. In the cross-bar group, 33% (51\/157) received three bars in XI fashion to cover the upper depression. The cross-bar group was older (18.0\u2009\u00b1\u20096.1 vs. 15.7\u2009\u00b1\u20095.0), had higher depression index (1.9\u2009\u00b1\u20090.7 vs. 1.8\u2009\u00b1\u20090.3), and was less asymmetric (45% vs. 71%) than those in the parallel bar group. The overall complication rates were not different between the two groups (9.6% vs. 10%, p\u2009=\u20091.0), although the cross-bar group was more rigid and complex. There was no bar displacement or reoperation in both groups.<\/jats:p><jats:p>\n          Conclusion\u2003The cross-bar technique is as safe and effective as the parallel-bar technique, even though it was selected to correct more complexities. The cross-bar technique could be a method for complex PE deformities for remodeling of the entire chest wall.<\/jats:p>","DOI":"10.1055\/a-1897-7202","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T23:13:45Z","timestamp":1657667625000},"page":"310-318","source":"Crossref","is-referenced-by-count":7,"title":["The
