Histopathological evaluation of the implants. An incisional hernia defect was created in rabbit abdomen. Three weeks following the primary surgery, the defect in each rabbit was repaired with HADM or PADM. Inflammatory response to the implant materials and the growth of fibrous tissue and neovascularization in the implants were evaluated at 4 (A) and 20 (B) weeks later using the following scale: “0” = within normal limits, “1” = minimal, “2” = mild, “3” = moderate, and “4” = marked. HADM, human acellular dermal matrices; PADM, porcine acellular dermal matrices
