520cc or 560cc Natrelle and are they the same? (Photo)

Question

I’m 5’3; 160 lb; 40 y/o. Which size should I go with? 520cc, high profile, Natrelle? Or 560cc extra full profile Natrelle? I would be going under muscle. From what I understand there isn’t much of a difference in size, but I would like some enlightenment on this. I have tried both on, I do like both. My concerns: will I lose ccs going with the 520? Will I look like I have a bigger build with the 560?

At 5'3 and 160 lbs you need to consider what a big implant
could do the your overall appearance. Big breasts can make 
you look heavy.  The difference between a 520cc and 560cc
is small in your case judging just by your picture. A second
opinion is always helpful. Best wishes.

Thank you for your question regarding implant sizing.

A 520cc implant and 560cc implant are not the same. There is a 40cc difference between the two sizes in question. Not only is there a volume amount difference, but there is also a profile difference. As stated in your question, the 520cc implant is a “high profile” (I’m assuming you are referring to a full profile) and the 560cc implant is an extra full profile which will “stick” out slightly more as well.

Knowing your base width diameter would be helpful as well. I recommend that you try on incisors at an in person consultation with you were more experienced board certified plastic surgeons to be sure.

Hello Touchheat.

Thanks for your question.

The best way to make a decision about 520 versus 560 is to discuss your goals with your plastic surgeon. I also believe you will find your answer by returning to your plastic surgeon's office and trying on the breast implant sizers again. In our practice, we let patients return as often as necessary to try on sizers and make their choice at their own pace. There sure is a difference between your two sizes, but not very much. Once you go to over 500 cc, they're in the same range, but the 560 cc is bigger for sure. Clink on the link and video below for more useful tips on sizing.

Best,

The difference in volume and diameter is going to be very minimal as 40ccs is not going to be visibly noticeable. Select the one that boosts your self esteem.

Thank you for your question.
The implants you have indicated are very similar. There is a slight difference in projection that probably isn't going to make a major difference in appearance. I would say that in general, I prefer full (#1) or moderate (#2) style implants to Extra full (#3). I think the geometry of these styles works well with most women's bodies.
In my opinion, the extra full is for someone who is trying to get maximum volume and projection. In order to get the highest volume with the narrowest base width, the implant has to be the most round. The reason I tend to advise the full over the extra full is in some women this can mean the transition from native breast to implant in the upper pole of the breast can be a little more abrupt and therefore look less natural and more augmented. This is not necessarily a bad thing simply a matter of desired appearance. 
I think a little information on implant sizing and how geometry influences the dimensions. 
Many physicians prioritize the base width of the breast to serve as a general starting point for choosing implants. Volume can then be decided based on the ability of the tissue to stretch and the desired size. Thus, in the natrelle catalog you have 5 implants with a base width of 13.25cm. As the volume goes up, the projection increases because it doesn't get wider so greater volume can only be achieved with projection. 
Example : all of these implants have base width 13.25cm
low profile plus (SRLP) 340cc projection 3.5cmmoderate profile (SRM) 405cc projection 4.4 cmFull profile (SRF) 520cc projection 5.5 cmExtra full profile (SRX) 560cc projection 6.3 
I think both are likely good options for you. you should speak with your plastic surgeon if you still are unsure. 
best of luck,
Dr. Rapp

Based on the one photograph (I like the Jack-O-Lanterns!) you have a very wide breast width.  I would choose the implant that has the wider base diameter to fill the space.

Good Luck and Happy Halloween!
