Do you lose volume when going under the muscle?

I am 5' bra is 34 A, but if I measure, it says BA is in two weeks...doing Mentor Moderate Profile Plus, Silicone gel & I chose 375cc under the it true that if I get 375cc's, they will look 25cc's less...more like 350cc's? Will I achieve a full C?

Thank you for the question. No, in my opinion, it is not possible to accurately determine how many CCs the you would “lose” when undergoing sub muscular breast augmentation surgery. I would suggest that you do not make your decisions based on statement such as: “you will lose 25 or 50 cc of volume when breast implants are placed under the muscle”. These statements are simply not reliable enough to utilize clinically. Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery (regarding breast implant size/profile selection) is:

1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work. Sometimes, it is necessary to seek several consultations before you feel comfortable about your choice.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals.
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "C or D cup” etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, best not to discuss your goals and/or judge the outcome of the procedure performed based on achieving a specific cup size. The use of computer imaging may be very helpful during the communication process. The use of in bra sizers may also be helpful. In other words, use as many “visual aids” as possible during the communication process. I encourage patients to meet with me as my times as necessary, to feel comfortable that we are both on the “same page”.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery. I generally select appropriate breast implant size/profile after the use of temporary intraoperative sizers and viewing the patient's chest in the upright and supine positions.
I hope this (and the attached link, dedicated to breast augmentation surgery concerns) helps. Best wishes.

Volume doesn't change with implant position

but I always increase the size over what people like when using sizers in their unlined bra.  There is dead space and other issues that must be accounted for and by increasing the chosen volume by 10%, I've been very accurate with achieving the desired outcome by my patients.  So if you like a 350 cc sizer and use a 350 cc implant, you will look a little smaller than what you may have anticipated.

Implant under the muscle make it look smaller?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Thank you for your question. This is a common question in breast augmentation. In short, the volume of the breast will be the same no matter where the implant is placed. The muscle will be pushing down on the top of the implant when it is placed under the muscle, thus giving the breast a slightly more gentle slope compared to if the same implant is placed over the muscle. The look in your shirt between when you tried sizers on in the office and how you will look after surgery will be slightly different because the implant behaves differently once inside your breast and under the muscle (as outlined above). With the size of the implants you have chosen and your small chest diameter, you will likely be at the very minimum a C cup, lkely a D or possibly DD.

Implants Under Muscle Changes the Size?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
You ask a very important question.  And the answers offered are accurate in that placing a 375 cc implant under the muscle doesn't reduce the actual volume.  375 ccs under the muscle is the same volume as 375 cc over the muscle.

But I think you may also be wondering about how 375 ccs will look under the muscle compared with how a 375 cc sizer looks on top of your breast right now.  And if that is your question, then, yes, I think that if you "love the look" of a given sizer on top of your breast you may perhaps best get to that goal by putting a slightly larger implant under the muscle.

Best of luck!

Placing the breast implant beneath the chest muscle will not reduce the size

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Do not be concerned about losing rest implant size of the implant is placed beneath the chest muscle.

There are many distinct advantages and benefits to placing your breast implant under the muscle.  Immediately after surgery the breast implants are compressed into look smaller however with time the breast implant will settle into the pocket and look normal and in most cases more natural than breast implants placed under the gland.

If you're really concerned in your heart believe this will happen to you then simply ask your surgeon to place an additional 25 cc breast implant and your pocket but in my experience there is no difference.

Volume is the same

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The volume of an implant is the same whether it is below the muscle or above the muscle. The volume is also the same whether it is a saline or a silicone gel implant.

Placing the implant below the muscle (rather than above) and using a silicone gel implant (rather than saline) will both give a more natural appearance which may allow you to go with a larger implant and still achieve a natural result.

If you were told that implants placed below the muscle or silicone gel implants will look 25cc less, that's not exactly true. They may appear 25cc less because they look more natural, but they will not be 25cc smaller.

Not true

No the same size of the implant is in there but it is slightly less obvious and more natural which is a way better look overall

Do you lose volume when going under the muscle?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
When the implants are placed under the muscle, the volume of the implant does not change. The muscle, however, can sometimes flatten the upper part of the implant and therefore slightly flatten the upper pole of the breast. This can be advantageous if the desire is for a gentle slope of the upper pole of the breast. Placing the implant above the muscle can give you a bit more fullness of the upper pole if that is the desired goal. The decision about above or below the muscle is one that is made after examining the breast, taking measurements, and having a discussion about your goals and desires. If you have any questions before surgery, ask your plastic surgeon to make sure all your questions are answered. Your cup size will not change as a result of the position of that implant. Good luck!
