Biomechanical research of different polypropylene meshes in breast ptosis correction / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the biomechanical properties of different polypropylene meshes, so as to select the proper mesh for breast ptosis correction as inner bra.</p><p><b>METHODS</b>Mini-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.</p><p><b>RESULTS</b>The tensile strength, stress, relaxation and creep of the four meshes were different. The material and the knitting of the four meshes were different.</p><p><b>CONCLUSIONS</b>The 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.</p>
