title: Form stability of the Style 410 anatomically shaped cohesive silicone gel-filled breast implant in subglandular breast augmentation evaluated with magnetic resonance imaging.
abstract: BACKGROUND
  In this study, the authors evaluated the form stability of the Style 410 anatomically shaped cohesive silicone gel-filled breast implant after subglandular implantation.
  
  
  METHODS
  Nine women who had undergone bilateral subglandular breast augmentation using Style 410 implants were examined in the prone and supine positions with magnetic resonance imaging.
  
  
  RESULTS
  In the supine position, the dimensions of the implants were similar to those specified by the manufacturer. In the prone position, there was a mean increase of 29.5 percent (range, 9.7 to 53.3 percent) in implant projection. All implants had their point of maximal projection positioned in the lower pole in both positions.
  
  
  CONCLUSIONS
  The Style 410 implant is described as a form-stable, anatomically shaped, cohesive, silicone gel-filled implant. However, its shell and the degree of silicone gel cohesivity allow for a change in form depending on body posture. Compared with the supine position, there was a marked increase in implant projection in the prone position. The Style 410 implant keeps its lower pole fullness after subglandular implantation in both the supine and prone positions.
