假体为基础的乳房重建（IBBR）可以减少或避免自体组织乳房重建手术供区的损伤和瘢痕，近十年来逐渐成为了乳腺癌术后主要的乳房重建方式，同时随着材料学的进步和乳腺外科的发展，补片材料辅助技术已经广泛应用于IBBR手术。特别是对于需要植入较大假体的病例，借助人工材料联合胸肌，起到“延伸”肌肉组织、无张力覆盖假体的作用，使重建乳房下皱襞更为饱满、自然，进一步降低手术创伤的同时也增加了重建乳房的美学效果。近期在国内进行的补片材料应用情况调查显示：我国区域经济发达状况和患者的经济条件是选择乳房重建和人工补片应用的主要因素。此外，由于中国女性乳房的形态特点不同于欧美女性，对于乳房体积较小的假体乳房重建，较少应用人工补片，因此，国内重建补片材料的应用更具个体化和区域性。

Implant-based breast reconstruction（IBBR）can reduce or avoid donor site injury and scarring in autologous breast reconstruction. IBBR has become the most common approach in breast reconstruction after mastectomy in recent ten years. With the progress of materials science and the development of breast surgery，mesh-assisted techniques has been widely used in IBBR，for the patients who need to implant larger volume prostheses，artificial materials which combined with pectoral muscles can “extend” muscle tissue and cover the prostheses without tension，and remodeling the fuller sub mammary folds. Matrices have been more applied in China in recent years，further reducing the surgical trauma and increasing the aesthetic outcomes of breast reconstruction. The investigation on the application of matrices in IBBR in China showed that the regional economic conditions and the economic conditions of patients are the main factors for the choice of breast reconstruction and matrices application. In addition，due to the different morphological characteristics of Chinese women's breasts，which is smaller than European and American women，matrices are less used for breast reconstruction with small breasts. The application of matrices in IBBR in China is more individual and regional.
