To Cross or Not to Cross: The Cross-Bar Technique to Correct Pectus Excavatum With “Costal Flaring”
The minimally invasive repair of pectus excavatum (PE), introduced by Nuss in 1998, represents the worldwide “gold standard” procedure for surgical repair. Modifications over years included routine use of unilateral or bilateral thoracoscopy as well as sternal elevation before starting the substernal dissection.
