Capsular Contracture and Implant Choice

It's unlikely that your choice of silicone vs. saline will dictate the success of your procedure. Replacing the implants does makes sense, as some capsular contracture (cc) arises due to bacterial contamination of the implant. Going smaller will present some challenges.  Depending on your skin tone, you may have excess skin after changing implant size and a breast lift may become a consideration.  The internal pocket will be also oversized for the new smaller implant (especially after capsulectomy), and you will need to use a round implant such that rotation of the implant will not create a deformity.  Switching pockets or doing a capsulorrhaphy are other important considerations.  Good Luck!
