对9名女性志愿者患者进行了隆胸手术，以确定三种纹理表面对纤维包膜形成的影响。表面纹理的高度减少了包膜纤维组织的形成，根据表面纹理的开孔直径和深度所产生的纹理的程度来分布患者。通过大体观察和组织学检查评价种植体的质地和纤维包膜界面。磁共振成像建立了与Baker分级所实现的乳房坚固度的相互关联，将平行四边形法则应用于从同一初始点到纹理表面凹陷或起伏的线性向量，以获得最终的收缩向量。它们与纤维包膜上生成的载体相同，只是方向相反。纤维包膜上的植入物质地的粘连效应或镜像组织反应显著减少了包膜收缩，但仅限于大质地植入物。由于植入物表现出微小和中等的表面纹理，两者之间没有显著差异，因此增加了包膜收缩。Biocell(TM)植入物在长度较小和相似的包膜界面上创建了方向不同的合成载体，创造了自然的乳房坚固性。聚氨酯(TM)泡沫的生物降解破坏了质地，不同长度和不同方向的合成载体，从12个月起增加了乳房的坚固性。Siltex(TM)植入物产生的与纤维包膜垂直的合成载体很少，而且非常长，在9个月后形成纤维包膜收缩。我们的结论是，表面有宏观纹理的植入物显著降低了纤维性包膜收缩的风险。
Breast augmentation was performed on nine female volunteer patients to determine the influence of three textured surfaces on fibrous capsule formation. The high degree of surface texture reduced the capsular fibrous tissue formation.Patients were distributed according to the degree of texture created by the open-pore diameter and depth of the surface texture. Macroscopic and histological examinations were performed to evaluate the implant texture and fibrous capsule interface. Magnetic resonance imaging established a mutual correlation with breast firmness achieved by the Baker grade.The parallelogram law was applied to linear vectors arising from the same initial point into the concavities or undulations on the textured surface to achieve the resultant contraction vector. They were identical to resultant vectors created on the fibrous capsule except in the inverted direction. The adhesive effect or mirror-image tissue response to the implant texture on the fibrous capsule noticeably reduced capsular contracture but only with macrotextured implants. Increased capsular contracture resulted from implants showing micro- and medium surface texture with no significant difference between them.Biocell (TM) implants created resultant vectors on the capsular interface of small and similar lengths with divergent directions creating natural breast firmness. Biodegradation of Polyurethane (TM) foam disrupted the texture from creating resultant vectors of long and different lengths and in variable directions, increasing breast firmness from 12 months. Siltex (TM) implants created few and very long resultant vectors perpendicular to the fibrous capsule that developed fibrous capsule contraction after 9 months. We conclude that implants with macrotextured surfaces significantly reduced the risk of fibrous capsular contraction.
