Is this a good result? 415cc over the muscle HP Sientra

Thank you for your question.  You are still early in your post operative course.  They usually will get to their final position in 6 to 12 months.  One will usually drop faster than the other, and the shape may go through various changes.  Please follow your Board Certified Plastic Surgeon's post op instructions. For example; we like message, but some surgeons will have you wait, or do it in a specific manner. Please let them know your thoughts and concerns.   Jeffrey J. Roth, M.D., F.A.C.S.

You have a great result, but honestly, what anybody else thinks is less important than what you think! Don't look for a reason (like a friend's comment or an "expert" weighing in) to decide you don't like what seems to have fulfilled your requests quite nicely.If you have textured implants, they are designed to adhere to tissues, and will therefore have less movement, drop, or settling than smooth implants, which will drop over time, aging, and gravity's (constant) effects, even with supportive bras.Your skin will stretch, and gravity works even on adherent textured implants, so there will be some dropping over time just like large "real" breasts. But slightly less with implants instead of your own tissue!If you want more "fake" upper pole roundness (or what I call the "Baywatch coconut" look), nothing wrong with that--and I actually think you look nice nude--you can be even more enhanced superiorly with a good push-up bra.Within the limits of your anatomy, tissue tensile strength and elasticity, and your goals and joint choices with your surgeon, this truly achieves as close to the look you aspire to without a capsular contracture, which can give you even more of a "fake" look, but at the cost of unnaturally-firm (hard) and painful croquet balls in your vest pockets. (BTW, this is not a good way to achieve the look you prefer, so this is a home run, in my estimation!) Cheers, and kudos to your surgeon. Best wishes! Dr. Tholen

You have an excellent early post-operative result.  The breasts appear to be symmetric, the implants are in good position.  Continue to follow your surgeon's post-operative instructions to maintain a good result.
