Would an implant with larger base width than my breast make a noticeable difference?

It is unlikely that 2mm will make much of a difference. But, with any changes to the implant profile and size, it is best to talk to your surgeon to see if it will work with your body and your goals. Hope that helps.

While it is always best to let base width be your guide for implant selection.

That being said, 2 mm is unlikely to make or break a result. It is also important to appreciate relative differences. The wider the base width, the less consequential a small degree of excess will be.

As always discuss your concerns with a board certified plastic surgeon (ABPS).

Dear JamieBennett85,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.

While it’s difficult to say for sure without examining you, 0.2cm of difference should not be a major issue as long as your surgeon plans your pocket accordingly. It should also be less of an issue for someone with a base width of 13 compared to someone with a base width of 10 as the relative difference would be less.

Thanks for your question. The short answer to your question is: probably not. Implant choice is a tough part of breast augmentation. All plastic surgeons have different approaches to making the implant selection. For the most part, most such approaches are valid. My personal choice is to begin by size choice. You know how you want to look. You have to make the surgeon understand your preference. The use of breast and implant dimension is very important, but has to be made within the context of your desires. In my experience, three dimensional photographic simulation is often the best part of the consultation. Make sure that you are in synch with the surgeon you choose. Keep in mind that 0.2 cm is two millimeters, that's pretty small.

In my opinion, it is best to choose a breast, implant closest to your measure based diameter. You can increase volume by choosing a higher or Fuller profile.

After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size 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 is right for them. Whichever you choose, it takes 3 to 5 weeks to get used to before you feel the implants are part of you. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

I don’t buy into the breast diameter method of selecting implants. I select implants based on how large a patient wants to be then I select based in volume

If the implant you selected is 0.2 cm wider than your breast base width (BW), that is 2 mm wider and well within the margin of error of breast base width measurement. Your implant essentially matches your breast base width. Skin thickness, amount of breast tissue, how your BW was measured, and how the implant is inserted all influence your outcome more significantly than 2 mm variation of implant width.

The .2 cm difference will still fit your base. If you have a wide gap between your breasts, this will work well. If you are very narrow between your breasts, this might be too tight.
