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
