Abstract: Objective Implanting surgical meshes to support breast in periareoler mammaplasty shows an excellent prospect.But shrinking of the mesh and the adhesion formation affected the postoperative shape and palpation of the breast.The aim of this study was to compare biocompatible properties of four different polypropylene meshes (Prolene(R) ; Vypro Ⅱ(R) ; Premilene Mesh (R) and Premilene Mesh LP(R)) and to discuss the inclusion criteria of meshes in this technique.Methods The study was carried out in pigs.Four different polypropylene meshes were implanted subcutaneously in belly.90 days after implantation the mesh samples were explanted,and complications,foreign-body reaction,collagen fiber and elastic fiber formation were observed,as well as ultrastructures for the biocompatible properties.Results The biocompatible properties of each mesh were different.The foreign-body reactions determined the biocompatible properties,and affected the postoperative shape greatly.Conclusions Premilene Mesh LP o as a newer low-weight polypropylene mesh,has superior properties to the others.
