What is the size difference between a moderate profile and high profile silicone implant?

Thank you for your question.  A 450 cc moderate profile and a 450 cc low profile implant will have the same volume.  The high profile implant will be narrower but stick out more the moderate profile implant will be wider and flatter.Unfortunately, this can sometimes be confusing for patients so here is the thinking that I use in my office.  We have the implant sizers for our patients to try on.I start with a moderate profile implant and change the size until the width of the implant fits the chest nicely and has just enough curve under the arm to balance with the curve of the hip.  To me, the diameter of the implant is the most important part.Once we find the correct diameter we begin to play with projection.  If the patient likes the diameter but wants to be smaller we look at a similar diameter implant in a low profile.  If the patient likes the diameter but wants to be larger we look at the same diameter implant but in a high profile.So, I would encourage you to think about how the diameter of the implant fits with your hips and your shoulders and then think about which style, high and moderate are low appeals to you the most.  Don't just go by the numbers, go by how the implant that your frame.I hope that this thinking will be helpful to you.Best wishes. 

Both implants you describe have the exact same volume, but they have a different shape.The moderate profile implant will be wider and not project as much.The high profile implant will be narrower and project more.The cc's are the same for both implants.This is confusing for a lot of women.  If you want more information regarding breast implants and breast augmentation you can download my free breast augmentation planner at aBetterBreast.com
