Most common congenital malformation of the thorax, Pectus Excavatum affects about one in 500 people. Several surgical or medical techniques have been proposed. Some are followed by complications or insufficient results even though their constant functional value is highly controversial. Secondary surgery with a deep customized 3D elastomer implant, may be an elegant effective and safe solution compared to others; it allows a good aesthetic result expected by patients in the absence of any respiratory or cardio-vascular functional context.
