Abstract:
OBJECTIVETo investigate the biomechanical properties of different polypropylene meshes, so as to select the proper mesh for breast ptosis correction as inner bra.
METHODSMini-pigs were used as animal model. Four different polypropylene meshes were implanted subcutaneously at abdomen. 90 d later, the specimens were taken out for biomechanical study.
RESULTSThe tensile strength, stress, relaxation and creep of the four meshes were different. The material and the knitting of the four meshes were different.
CONCLUSIONSThe biomechanical properties of relaxation and creep are important in maintaining the postoperative breast figure. Premilene Mesh LP is a new and light polypropylene mesh with mini-pores. Its biomechanical properties are superior to the others.
