The More Breast Tissue You Have, the More Ccs You Need for Implants?

The general rule of thumb here is that the less breast tissue there is, the larger the volume of the implant to acheive the same postop size. Also, the more breast tissue there is the more likely you could go over the muscle. It is unfortunate that we don't have a more reliable way of discussing breast size than the cup system, which was introduced by the Warner Bros. Corset Company in the 1930's as a way of inferring breast size without doing actual measurements that would be considered impolite. What you really need to do is forget about cup size for a moment and try on implants in a bra to see what just looks right. Your plastic surgeon can then determine what volume of implant and what dimensions are needed to acheive what you want.

Interesting point but it's not quite correct. It all depends on where you're headed. If you have a C cup breast, that doesn't mean that you need a larger implant than someone with an A cup...you have different goals. The A cup patient may want a small difference and the C cup patient may want to fill the upper pole.
The truth is that if you are already a C cup and are wanting a larger breast I sometimes wonder, how much larger? Is the goal a DD? F? G? There comes a point where it is fairly predictable that you won't be happy with some of these very larger sizes in the short term.
Often, patients need a lift and will only fill out their upper pole with an implant. In those cases, the implant does not need to be the same size as the breast tissue to make a difference, that could result in a still low implant that now hangs with the breast. Be cautious when making this assumption as I believe it to be inaccurate, particularly if you have low sitting breasts on your chest wall.
Nonetheless, measurements must be made by your board certified plastic surgeon and a clear discussion should be had with open comments about your concerns. Only then can you achieve your true aim after surgery.

Hi,
Thank you for your question.
Every patient is different. The same-sized implant can have a different effect on different patients. Even patients who are relatively the same "cup" size pre-op, can require different shaped and sized implants to achieve the same look. Cup size is never promised. There are other factors such as skin laxity, nipple placement, droopiness, etc that can affect the result of a certain size of an implant regardless of breast volume.
The implant will push out the tissue you already have when placed over the muscle causing more of a projected look. When the implant is placed under the muscle, it is kind of compressed and more natural looking.
Best regards,
Dr. Speron

Within limits, the statements you make are correct:

It generally takes increasing volume to achieve an incremental increase in cup size. However, please realize that there is some subjective interpretation and inherent inaccuracy to the cup measurement. As bra options become increasingly complex, it is not only breast volume but also breast shape that may determine the cup size. Cup size is a fashion term (subject to interpretation by Donna Karan or Calvin Klein, etc.) whereas volume size is a scentific measurement. Furthermore, the cups come in different configurations such as full, demi, soft, structured, padded, sheer, etc.
When you go OVER the muscle the implant will push forward whatever existing breast tissue you have and enhance the projection whereas an implant will be compressed when placed UNDER the muscle.

Yes, in general if you have more breast tissue, you will need a larger implant to see more of a difference. However, other factors that come into play include how much skin stretching you have. Any implant will push out what is there, and when the implant is larger, you start to see more fill in the top of the breast. Good luck, nsn.

This is a very common mistake!
The final volume (size) of your breast is the current size PLUS the volume of the implant which is added. Therefore, the LARGER your current breast size, the SMALLER the volume needed to achieve a certain size. In other words, a "C" cup breast will require a smaller implant volume to achieve a "D" cup than an "A" cup breast.
The other common mistake it to go too large or use a large implant thinking that it will "lift" the nipple up. A very large, heavy breast will eventually stretch the skin and nipple area, and will eventually require a breast lift.

I think this sort "figuring" is not productive, and serves only to increase your anxiety.
I think it is more helpful to understand that the diameter tends to increase much ore than the projection as the size of the implant increases. As you overfill the implants, the projection increases while the diameter slightly decreases.
Implant size goes up around 30 cc's per size (Inamed) which is about a shot glass, which is not much.

A patient with large breasts may have a wider breast width diameter which may then put them in a larger implant than say a smaller breasted woman.

When a surgeon is considering an implant to use in breast augmentation, after taking the individual goals in mind, the size of the implant is influenced by the breast diameter, chest size, and breast projection needed. While there is a 'rule of thumb' that each change of say, 150cc, the breast size will increase by one cup size, the size of the natural breast plays a large factor as well.
Think of it as a percentage change in size of the breast. If you consider the A cup in a slender individual, a breast of about 100 grams, a 200cc implant will increase the breast size by 200%, a remarkable change for some. A more average frame individual with a B cup breast of about 350 to 400 grams with a 200cc implant will only realise a 50% gain in breast size. So true enough, I tend to use a larger implant when the natural breast is larger and vis versa.
Concerning a submuscular implant, the implant will push forward and conform to the breast such that they feel as one, hand in glove. Don't worry about implant size as this is the surgeon's concern. Focus on how you wish to look, and communicate this clearly before your procedure.
Best of luck!

You are partially right. The more breast tissue you have, the larger the implant has to be to see a significant change. Although going under the muscle or dual plane does push out what breast tissue you already have, this position requires a larger implant than one above the muscle to achieve the same bra cup size increase. Also, the larger the chest size, the larger the implant needs to be to achieve one cup size increase. However, for people with the same size chest, theoretically, the same size implant will achieve the same relative change in bra cup size, no matter how much breast tissue you start with.
