Commentary on: evaluation of the effects of silicone implants on the breast parenchyma.

BACKGROUND Despite being the cosmetic procedure most performed worldwide, there are still few objective measurements of postoperative volumetric analysis of breast augmentation available in the literature. OBJECTIVE The aim of this study was to evaluate volumetric changes in the breast parenchyma after the placement of silicone implants in the subglandular plane. METHODS Thirty-four women were randomly allocated to the intervention group (n = 24), who underwent breast augmentation in the subglandular plane, or to the control group (n = 10), who received no intervention. Volumetric magnetic resonance imaging was performed at inclusion, and after 6 and 12 months in all participants. The non-parametric Friedman's test was used for statistical analysis. RESULTS There was a significant reduction in glandular volume (mean, 22%) at 12 months postoperatively in patients who underwent breast augmentation. CONCLUSIONS Breast augmentation caused reduction in the volume of the breast parenchyma. LEVEL OF EVIDENCE 3 Therapeutic.
