Implant exchange from 450cc's to 650cc's

In my opinion, your desire for a fuller look likely can be met without going larger, but going to a plastic surgeon that specializes in breast surgery.  Going larger as you have stated will result in complications most likely as you age and gravity takes its toll. 

Thank you for your question. Larger implants can increase the incidence of late complication. If you have a small amount of breast tissue to begin with, a larger implant can stretch that tissue out to reveal ripples, distort the pocket, and cause malposition. Discuss this with your Board Certified Plastic Surgeon to see what the limits of your anatomy might be. I hope this was helpful.

450
cc implants weigh approximately 1 lb each and 650 cc implants weigh about ½ lb
more. The additional weight will cause skin
stretching resulting in inferior and lateral displacement requiring
revision. The other alternative is
reshaping your existing breast tissue with a new technique called The Mini
Ultimate Breast LiftTM. Using
only a circumareola incision it is possible to create upper pole fullness,
elevate them higher on the chest wall and more medial to increase your
cleavage. Aligning the areola, breast
tissue and implant over the bony prominence of the chest wall maximizes
anterior projection without changing out the implants. This may give you the look you desire while
avoiding the ugly vertical scars of the traditional technique, maintaining
nipple sensation and the ability to breast feed. Best Wishes,Gary Horndeski, M.D.
