Textured or smooth implants for breast augmentation? A prospective controlled trial.
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.
