  8. 8. Why Mesh? Pathogenesis of Hernia  Defective Collagen  Reduced ratio of type I and type III collagen  Type I: MatureCollagen, strong and normal tissue  Type III: ImmatureCollagen, weak, in healing wounds  Type I :Type III ratio normally is 4:1  ?Genetic defect  Connective tissue pathology is not only a cause of primary herniation but its presence can prevent cure! A role for the collagen I/III and MMP-1/-13 genes in primary inguinal hernia?
