It depends upon your tissues!

I'm going to assume two things: you don't want to look fake and you don't want to cause irrepairable harm to your tissues. Is that correct? Once in a while I see a patient that wants to look fake and doesn't care if she stretches and thins her tissues which will cause her severe deformities later, but that is very, very rare.

So if you don't want to look fake and damage your tissue, then it is actually not about what you want - it's about your tissues. After all, the implant is going in your breast tissue - not into the wishes in your mind! If a shoe must fit your foot, a heart valve must fit your heart, then so too must a breast implant fit in your breast. If it is too large it will look stuffed, round, and have visible edges.

The determination of the ideal implant size for a specific patient has been very well described, and has been published in the top plastic surgery journal. With just several measurements, your surgeon should tell you exactly the best sized implant to fit your tissues. If you go down from there, your upper breast will look empty. If you go up from there, it will look bulgy. It's that simple.

One such system is called "High Five" and it was published in Plastic and Reconstructive Surgery by Tebbetts and Adams. This remains the "gold standard" of tissue based planning in that it was the largest such series of patients published to date.

I see a lot of patients for revision surgery, and I can tell you that without a doubt allowing patients to dictate implant sizes based upon their wishes for a specific cup size and not what is dictated by their tissues creates lots of problems later!

Don't go too big, whatever you do.

We are constantly hearing from women who are miserable with their huge breast implants. They age very badly.

Without knowing anything else, I would guess 200 cc's might be good for you. What we recommend in New York, is that your surgeon use disposable implant SIZERS during surgery to see which size looks best on you, before opening the permanent implants . This takes the guess work out. And tell him to be conservative.

There is no way to guarantee a particular bra size. Bra sizing varies greatly between bra manufacturers and a C in one bra will be a D in another. What matters more than the assigned bra size is the way the implant looks on you. The best option for your body and aesthetic goals can be determined in a thorough implant sizing session.

Implant sizing depends on several factors. One of the most important factors is your breast width. Generally, your surgeon will measure your breast width, and then provide you with a range of implant sizes appropriate for your native breast size. There are more nuances to it than just what I've described, but this approach works for most women.

I usually have my patients bring in a large bra and a tight t-shirt to do sizing. I'll then choose 3-4 implants that I feel are appropriate, and have my patients place them in the bra under the tight t-shirt. My patients can then look in the mirror and get a good sense of what they will look like with the provided implant sizes. My patients like this approach and get a great idea of how they will look.

By using this technique, your surgeon can outline a range of appropriate implant sizes that will be aesthetically pleasing, and you make the final decision.

I hope this helps. Good luck!


Sizing an implant

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The first thing to consider is the "look" you want to achieve in the end result. How much upper pole fullnes do you want vs. how "natural" do you want it to be.

Base width of your chest wall defines the diameters of implants that will look good on you. The profile determines the fullness you get with the moderate being the most natural, the moderate plus being slightly fuller and the high profile being the fullest for your body.

Finally placing implants in garments can roughly simulate the look so you can participate in the decision process. Good luck!

The size can vary. It depends on how wide your breast is. Surgeons refer to it as the "Base Diameter" or "Base Width." Only implants that are as wide as your breast or less wide can be used. This will limit the size to some extent.

Implants come in three general profiles. That is moderate, moderate plus or high profile. If you take a moderate profile implant and a high profile implant of the same width, the high profile implant will be able to hold more volume than the moderate profile. This is because it is taller than the moderate profile.

Because it is taller, the high profile has more of a round shape. The moderate profile looks more like an oval. The moderate profile is somewhere in between.

In general, moderate profile implants create less fullness over the superior part of the breast. The moderate PLUS profile has more and the high profile has even more fullness. The more fullness you have over the superior part of the the breast, the more round the breast will look.

Thus, the choice of implant has to do with how big you want to be and what kind of shape you want. If you want a very natural tear drop shape to the breast, you will do better with a moderate profile implant. If you want more of a full round shape throughout, you will do better with a high profile implant.

You should have a very detailed conversation about these options with your surgeon. This will make it more likely you will be happy with your end result.

Well, it depends...

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

In the old days, there was only one "profile" implant so you were kind of stuck with a particular size that had a width that matched the width of your breast. This is no longer true.

Now we have several profiles of implant - each of which has a similar width but a different amount of projection. Using a 12 cm breast width, the implants (in this example Allergan's Natrelle ) could be anywhere from 240 cc to 425 cc. Obviously, which is "best" is a matter of your taste. When you visit your plastic surgeon they should be able to help guide you in making this decision.

Good luck!

It depends on that you want.

Surgeons choose implant sizes based on many different theories with good results. Personally, I first select an implant with a width appropriate for your chest, then determine how much fullness you want in the upper part of the breast (similar to the effect you get with a push-up bra). If you wear a 32something bra (32A), you'll want implants that are about 11cm wide, then chose moderate, moderate-Plus, or high profile impalnts. That will determine if you use a 175cc, 250cc, or 325cc implant. So which one is right for you? It takes a good conversation with a board certified plastic surgeon to get a clear picture of what you want and it is his/her job to make sure you're not doing something foolish! Good luck!
