The authors present a new study on 789 cases of congenital thoracic malformations including 638 pectus excavatum and 151 Poland syndromes, according to a new classification which completes Chin's one. All these malformations were treated with silicone elastomer implants. The contribution of computer-aided design and manufacturing (CAD/CAM) since 2008 is essential. The one-stage surgical protocol is precisely described. The results are impressive, permanent, for life, and complications are rare. The authors evoke a common vascular etiopathogenesis theory at the embryonic stage and question the heavy techniques of invasive remodeling that are most often unjustified.
