This book with accompanying videos focuses on pectus excavatum correction using custom-made silicone implants. It discusses patient evaluation, the minimally invasive procedure and follow-up care. It also describes in detail, and in a way that is comprehensible for practicing clinicians, the procedure for creating silicone implants using a scanner (computer-aided design). Further, the book presents the possibility of using fat grafting to correct this congenital deformity and highlights secondary surgical procedures and complications (e.g. infections). Correcting pectus excavatum using a computer-aided design silicone implant is a simple and reliable technique that yields high-quality, aesthetic results. In the medium term, the approach may render invasive techniques obsolete, however, these operations remain risky.
