摘　　要：目的　探讨聚丙烯网的乳房塑形和支持作用。方法　以小型猪作实验动物 ,在其皮下置入聚丙烯网 ,用扩张器扩张未加网和加网的皮肤 ,模拟重力对乳房皮肤和置入的聚丙烯网的牵拉作用。分两次采集标本 ,进行生物力学和组织学研究。结果　与正常皮肤相比 ,未加网扩张皮肤的生物力学性能降低 ,组织学性质改变 ,而加网的扩张皮肤则否 ;聚丙烯网的抗张强度和弹性模量均远小于皮肤。结论　聚丙烯网对受牵拉的皮肤有明显的保护作用 。Objective To study the polypropylene mesh acted for the moulding and support. Methods\ Four mini pigs were used in this experimental research. A polypropylene mesh was implanted under the skin on one side of each pig. An expander was thereafter placed in the deep layer to imitate the action of gravity to the skin and mesh. The specimens were collected in two different times for the biomechanics and histology examinations. Results\ The biomechanical data were shown lower and the histological properties were found changeable in the expanded skin without the mesh support, compared with the normal skin. However, the changes did not occur in the expanded skin with the mesh support. Furthermore, the tensile strength and elastic modulus of the polypropylene mesh were significant less than the human skin. Conclusion\ The Polypropylene mesh could prevent the extended skin effectively and has moulding and support effects.
