This study examines the hypothesis that textured surface silicone implants reduce the incidence of adverse capsular contracture in breast augmentation. A total of 53 patients were entered into a prospective study; they were randomly assigned to receive either smooth or textured implants which were placed in the submammary plane. Of these, 50 patients were assessed at 12 months by a panel of observers who did not know which type of implants had been used. Adverse capsular contracture (Baker grades 3 and 4) was found in 28 breasts augmented with smooth surface implants (58%) and in 4 breasts in the textured surface implant group (8%). This reduction in adverse contracture using textured surface implants was highly significant (p less than 0.0001). Careful trial design is essential in studies of this sort in order that we can obtain useful data regarding the causes and prevention of adverse capsular contracture.
表面有纹理的硅胶植入物可降低隆胸手术中不良包膜挛缩的发生率。共有53名患者参与了一项前瞻性研究;她们被随机分配接受表面光滑或有纹理的植入物,并将其置于乳腺下平面。其中,50名患者在12个月时由一组不知情使用了何种类型植入物的观察者进行评估。在接受表面光滑植入物隆胸的28个乳房中发现了不良包膜挛缩(贝克3级和4级)(58%),而在表面有纹理的植入物组中有4个乳房出现不良包膜挛缩(8%)。使用表面有纹理的植入物使不良挛缩发生率的降低非常显著(p小于0.0001)。对于此类研究,精心的试验设计至关重要,以便我们能够获得有关不良包膜挛缩的原因和预防的有用数据。
