425 cc High profile silicone implants with lift, too big? Measurements and pics attached. (photos)

Probably. The 371 requires a base diameter of 12.9 and you are 12 and 12.5 on your spec sheet, so that won't work well. Also you so seem to have a thinner torso, and there is still quite a lot breast tissue, although it is ptotic.  If you wanted to go 425, theoretically the base width of 12.0 would work.  You just have to realize that you are going to be a D cup at least.   Active life style and large implants, combined with a lift that puts stress on already stretched and weakened tissue, not a good combination.  Think smaller in these circumstances. Perhaps trying on sizers and wearing them in your bra for a week, if your doctor would permit that, would save you some headaches, down the line.

Your pictures suggest that you would be an excellent candidate for breast augmentation performed in combination with breast lift surgery. Under these circumstances, breast lift surgery is utilized to re-shape the breasts and lift the nipple areolas into normal position. This will require removal of excess skin in both the transverse and vertical dimensions. In most cases this will require either a lollipop or anchor mastopexy.The size of breast implant utilized depends upon the patient's aesthetic goals and anatomic findings. Most patients want harmony, balance and proportion with the surrounding anatomic structures. They also want a natural look with superior breast fullness. In someone with a petite frame and a relatively active lifestyle, a smaller implant is definitely a consideration. Under these circumstances, a 371cc silicone isn't an unreasonable choice.In an effort to determine breast size in a more objective manner, we utilize external silicone sizers. External silicone sizers are designed to sit on top of the patient's breasts. They can be held against the patients chest or placed inside the patient's bra. This technique helps the patient visualize what their breasts look like with a specific sized implant. It also gives them a sense of the volume that will sit on their chest wall and how it feels.The ability to visualize your projected surgical result with sizers alleviates much of the anxiety associated with this procedure. It's also important to thoroughly discuss the issue with your plastic surgeon.

Hi Cali,It sounds like you are seeing a very carful surgeon, who does good preop analysis.  A narrower base implant make sense.  This is more fully outlined below by Dr. Lowen, so see his answer.  If the implant is too wide, you end up with a "Side-boob."  So, any way, all the best, "Dr. Joe"

I personally feel that, in order to get the best result, you would need more than just the circumareolar lift. In my opinion, you need at least the lollipop scars if not more. I would highly recommend asking your surgeon to review with you photos of women with similar anatomy.  This is very much surgeon dependent.  In my experience, the circumareolar lift does very little actual 'lifting'. 

You look tall, thin and athletic by your pictures.  Bigger implants mean they may get in the way of your activities and this is an important fact to take into consideration.  It is always possible that by putting in a larger implant, that your surgeon is trying to avoid doing a mastopexy (or lift) that would have more of a scar.  Sometimes it is okay to put in a little smaller implant and doing an different mastopexy, even if it means a little more scarring. It is important to talk to your surgeon again to see what his or her thoughts are for choosing that combination of surgery. Good luck with your board certified plastic surgeon!
