300cc or 280cc Breast Implants for Rounder Look?

Thank you for your question and for sharing your photo. Size of the implants can be very personal choices that a patient makes. In many cases, patients can go from a A cup to a D cup or larger. In our practice, I begin by asking whether you are looking for more projection or perkiness and whether you mind have some of the breast tissue push outwards on the side. In addition, I ask you to try on different external sizers to give you a sense of what your breast may look like and the feel of extra volume in the breasts. In addition, I take details measurements of the breast including the base diameter of the breast. Your volume range and the breast shape preferences helps me the further guide you in your implant selection and to give you guidance on what the breast might look. I would visit with some board certified plastic surgeons in your area to discuss your options and goals in more detail.

Sounds like your plastic surgeon may be giving you sound advice. Here is my take on this subject:It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 300 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the following link:

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!

The question
of breast implant size is always difficult for prospective breast augmentation
patients.In this case, it’s virtually
impossible to answer the question of breast size without more information.Without pictures or a physical examination,
it would be only guesswork.For these
reasons, multiple approaches are utilized to make this determination
preoperatively.These include reviewing
magazines, photographs, external sizers, and recently the 3D Vectra computer
imager, to name a few.Even when tremendous care is taken
preoperatively to determine breast size, the final decision needs to be made in
the Operating Room by the surgeon.At
this point, an assessment can be made regarding how the patient’s breast tissue
interacts with the breast implant.Occasionally, obtaining a specific size doesn’t allow the surgeon to
meet the patient’s other aesthetic goals.For this reason,locking into a
specific size isn’t always a good idea.Results are better when a surgeon has the ability to make adjustments in
the Operating Room.It’s also important to realize that,
for many patients, a 25 cc difference in breast size would be difficult to
notice.In reality, a 25 cc difference
is less than two tablespoons, which is spread in three dimensions over the
implant.In your case, I think it’s important
to thoroughly discuss your aesthetic issues with your surgeon.Make sure he has the latitude to do what’s
best for you in the Operating Room, so he can meet your aesthetic goals.It’s important that you have an approximate
idea of the breast size that you’re considering, but don’t become married to an
absolute number.

Twienty cc is a minimal difference and will make little, if any, impact on the outcome of the procedure.

If you want a rounder look, that is what your should get. We each have our own opinion of what is attractive. Keep in mind, a 300 cc MP is a totally different shape than a 300 cc HP and they each fit different chests. If you fit a 300 cc MP, the 400 cc HP will fit you. It is not a big implant and I put them in every day. Good luck!

This is a very small difference in size that will be difficult for anyone to notice a size difference.   Unfortunately, there is not a general rule of thumb or objective criteria to implant selection to replace an in office exam and good communication with a board certified plastic surgeon.

Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.

There is very little difference between these two implants and more than likely you would do well with either type.  Given your petite chest circumference I do not believe that a 300 cc implant would be too large.  Atlanta Plastic Surgeon,  DR. Z

It is very important to communicate your size goals with your surgeon.  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 cup” or "fake looking" means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.
I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the press implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible.
By the way, the most common regret after this operation, is “I wish I was bigger”.
I hope this helps.

A 300cc high profile implant might actually be on the small side for your height. It is important to measure chest wall basewidth to determine the right size for your frame. With time you may gain weight but your height won't change. Implants in the mid 200's to low 300's are average to small in our practice.
