I’m looking to get a breast augmentation and was recommended 300cc on left and 350cc on right. Any suggestions?

Dear kimanier, Thank you for your photos. I think you are a great candidate for a breast augmentation. One can appreciate the asymmetry from your photos so i think the difference in implant sizes is reasonable. This is a common practice to achieve more symmetry in certain individuals. The volume is based on many factors and I assume your plastic surgeon took specific measurements to help you choose reasonable volumes based on your body anatomy. If you think this may be too small, then talk to her/him and explain your goals. I think communicating will help you feel reassured that your end result will be met. Make sure she or he is a board certified plastic surgeon. Good luck, Dr. Suzette MirandaBoard Certified Plastic Surgeon

Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.
Another point which is often under appreciated is that of anatomy and starting point. Any implant will add volume to the volume which is already present. The implant is additive. A particular volume will not necessarily confer the same cup size to different patients (often times it will not even confer the same cup size to different breasts in the same individual...remember they are "sisters" not "twins"). 
A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.
When sizing patients, there are a number of useful tools including:
-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)
-Breast sizers (rice bags)
-Goal photos
I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant.The key to obtaining a natural result is to stay within the parameters defined by your BWD. With regards to your specific question, your current choices do not sound unreasonable (however, this is difficult to say with any certainty without an in-person exam). You demonstrate mild asymmetry (which is within the normal expected limits of variation). The difference between 300 cc and 350 cc will be subtle (slightly more than the volume of a shot glass).
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Thanks for your inquiry and excellent pictures, first by looking at your wish pictures you should be considering a high profile implant. Otherwise you seem to be in a good size range, good luck. 

Hello,It appears you have beautiful breasts to begin with. It is common to have slight asymmetry and for the surgeon to use different sized implants to even out the breast. You are correct, when implants are placed under the muscle, you lose 25-50cc of projection... very minimal. To achieve the look you have in the photos, I would personally recommend around 450cc. My best advice to you is to seek consultations with board certified plastic surgeons in your area. I hope this helps. Best Wishes, Dr. Lane SmithLas Vegas, NV 

Great question!  There are many factors when it comes to choose the correct breast implant and sizing.  You are correct in the fact that once the implant is inside the body and under the muscle, it will appear to be smaller than trying on the implant.  I generally tell patients to pick a size that is slightly larger or I will generally go about 10% larger than the size the patient desires.  A 300cc or 350cc implant size will generally get you about 1.5 cups bigger than you are now and looks like it could provide you with the wish photos.  However, only with an examination to measure your dimension and trying on implants in office will provide a more accurate recommendation.Best of luck and hope this information helps!

Dear kimanier,Thank you for your question. There are a couple approaches to achieve better symmetry after breast augmentation. One is to used different sized implants. Another is to take a small amount of breast tissue on the larger side and used same sized implants. I think both are reasonable approaches. Keep in mind that everyone has some asymmetry at their breasts.Best regards,Nirmal R. Nathan, M.D.Certified, American Board of Plastic SurgeryMember, American Society of Plastic Surgeons

Dear kimanier,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.

To answer your question about cc, you first need to take into account what's known as your base width diameter.Imagine lying on your back and drawing a circle around your breast. If you were to draw a line across that circle, it will be a given length. Your plastic surgeon will measure this length, which is called ‘’base width diameter’’ or BWD for short. For women, the base width diameter can go from 9.5 cm to 16.5 cm, or 3.75 to 6.5 inches. As you can see, there is a very wide range. 
300 cc on a woman with a BWD of 10 cm is very different than 300 cc for a woman with a BWD of 15 cm. On one it may be enough volume, and for the other it may be much less than the max she can safely go. 
As far as the placement of the implants, placing them under your muscles - this is still the most popular technique for a variety of reasons, one of the biggest advantages is that it prevents rippling and it also hides the implant better. It is probably still recommended to replace the implants under the muscle, but a discussion of your goals during the consultation will help determine the final position.
Regarding sagging, whether you have implants or not, aging, pregnancy and breastfeeding will do things to your body. When you’re pregnant, your body releases more hormones. You’ll gain weight. Your skin will be stretched by the pregnancy weight and lose some elasticity.  And after childbirth and breastfeeding, your breast will deflate and your skin will be looser. 
I hope that answers your question on size. It’s great that you’re doing this research. I always say that the best patients are informed patients.
You might also want to research your options for breast implants. Choosing the right implant is the number one concern among women considering breast augmentation. Did you know, there’s actually a way to select a implant shape, size, and profile that is perfect for you?
A term that I use with my patients for the perfect implant is the “Pony Implant”.
So, what do I mean by “perfect”? Well, a Pony Implant has three qualities to it. First, the implant meets your beauty goals. For example, you want to your breasts to look fuller while still appearing natural.
Second, when you chose your Pony Implant, you walk out of your consultation 100% confident that you’ve chosen the right shape and size for you. In other words, you won’t be second guessing your decision, and you won’t be afraid of having gone too big or too small.
And third, after your procedure, you are thrilled with your results, and say, "I’m so happy. This is exactly what I wanted!"
That’s the Pony Implant. And the great news is that there is a simple process to go about finding yours.
This issue of selecting the right implant is so important when it comes to patient satisfaction or dissatisfaction that, again, I really encourage you to learn more about it.
Thank you for reading and best of luck on your journey!

Hi and welcome to our forum!

Determining the “perfect” breast size before a planned breast augmentation is quite a difficult task. Each individual has a different concept of “normal” breast size. In addition, there is no standardization of bra size in the manufacturing  industry. One company’s “C” is another company’s “D”.

There are various ways to determine desired breast size. Bringing in “wish pix” to demonstrate to your surgeon will make him / her aware of your anticipated goals.  Placing an implant in a bra gives an extremely rough idea of anticipated breast size. One may estimate volume by adding rice to a baggie ( 1 cc 1 ml) and adding the volume to your breast beneath a bra. Some surgeons offer computer imaging.

The most important measurement is the base width of the implant. If you drop a vertical line from the medial most and lateral most aspects of the breast, and measure the distance between them, this suggests a base width. If an implant is too narrow, you will not have adequate cleavage. If wider than the base width, you will have excessive cleavage and “lateral boob”.  The fill of the implant then determines the amount of forward projection.

I recommend a thorough discussion with your plastic surgeon to ensure that you are both on the same page.

Best wishes…

Your pre-operative photos demonstrate a good starting shape for augmentation, with some natural volume asymmetry. Asymmetric augmentation (using two different implant volumes) is commonly performed, when necessary, to achieve better volume matching. Your Plastic Surgeon has likely already made a careful assessment of your asymmetry. However, if you have any lingering doubts about your sizing, I recommend that you return to your surgeon for additional discussion before proceeding.Dr. B
