Objective:
To investigate the biomechanical properties of different polypropylene meshes, so as to select the proper mesh for breast ptosis correction as inner bra.
Methods:
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.
Results:
The tensile strength, stress, relaxation and creep of the four meshes were different. The material and the knitting of the four meshes were different.
Conclusions:
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.
