Deciding between 275cc and 295cc - moderate profile round implants. I'm 5'2 and 110 llbs, 34B (photo)

Choosing the right size and profile breast implants for you: After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and style breast implants. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what size and style breast implant is right for them. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

Choosing an implant size/style is an important decision which is best made in concert with your surgeon. Ultimately, options are based on a number of factors including:
-Chest dimensions: This point is crucial as the width of your breasts defines the available "real estate" on which the foundation of your augmentation is built. This "foot print" is the absolute limit with which you are dealing. Too "large" is not so much the risk as too "wide." You cannot build a 3 acre mansion on a half acre plot. An implant which is too wide (exceeding the available space on your chest) will generally over hang laterally making it more noticeable and occasionally contributing to discomfort and nerve symptoms (numbness or tingling). This will also contribute to a more unnatural look.
-Tissue quality: This relates to size in the sense that the implant will be suspended by your tissue. Too large an implant may place took large a stress on these suspending tissues leading to healing problems in the short term and bottoming out in the long term.
-Patient desire (what is the look you are hoping to achieve?)
My role as a surgeon is to manage expectations and guide you towards a prudent choice which can satisfy these reasonable goals. Often times, a surgeon can guide a patient toward a size/cc range and patients will make determinations on implant style/profile. Patient seeking more or less projection, or seeking a more pronounced or subtle upper pole volume increase can be guided toward an implant which will help them best achieve their goals. Additionally, technique variations (sub muscular vs. sub glandular) can also aid in obtaining the look you desire.
There are a number of tools available to help guide patient/surgeon decision making including sizers, 3D imaging and goal photos. Each modality can help better communicate your goals to your surgeon and vice versa.
Ultimately, it is important to not marry oneself to a particular "cc" as oppose to a particular "look." Communication is key as you and your surgeon create your custom surgical plan.
With regards to your specific question, volume does not change but rather shape when comparing pre-op sizing to a final result. I would not struggle too much over a small volume differential (20 ml). This is less than the volume of a shot glass and is unlikely to make a very discernible difference in outcome.
As always, discuss your concerns with a board certified plastic surgeon.

Hello! Deciding between 275cc and 295cc moderate profile round silicone implants is a common dilemma, and it’s great that you’re taking the time to ensure the best choice for you.When trying on sizers at your consultation, they provide a general idea of the volume, but they don’t fully replicate how implants will settle in your tissue over time. Factors like chest width, skin elasticity, and natural breast shape all play a role in the final result.The difference between 275cc and 295cc is subtle (about 2mm in width and 20cc in volume), which may not be significantly noticeable once implanted. However, many patients do opt for the slightly larger size, as post-surgery swelling subsides and implants may appear a bit smaller than expected.If you are unsure, trying on sizers again is a great idea! Also, consider discussing implant placement (over vs. under the muscle), your natural breast tissue, and long-term aesthetic goals with your surgeon. The goal is a size that complements your proportions while making you feel confident.
