Anatomical and Surgical Principles of Ventral Hernia Repairs

Hernias comprise a growing problem in surgical science. The most recent classification scheme for hernias emphasizes on the size of defect as well as on whether it is an incisional hernia. The latter group includes complex hernias, namely hernias that can not be managed with simple surgical techniques. This can be accomplished with retromuscular repairs or the more complex anterior and posterior component separation techniques. An anatomic repair is usually reinforced with interposition of mesh. Newest techniques, such as the use of botulinum toxin to induce temporary paralysis of the lateral abdominal wall musculature, referred to as chemical component separation, now present new tools in the restoration of anatomy-based repairs. The chapter entitled “Anatomical and surgical principles of ventral hernia repairs” aims to describe the anatomical and surgical principles of current practice regarding the repair of ventral -primary and incisional-hernias
