Breast implant sizing issues

The width of the breast upright with the arms down is the key measurement for deciding the diameter of the implant that will fit it (and also determines the height for round implants). This width should be the same for both implants. The forward or projection volume of the implant could vary depending on overall needs for volume (which is hard to measure or determine) but the width needs to be the same for both sides. 2 mm is within the measured variation of a caliper measurement and is... more

2MM Size Difference-Should I Use Different Size Implants?

Thanks for your question. Breast width is just one of the dimensions plastic surgeons use to determine the volume of the breast. Other critical measurements are the height of the breast and the projection of the breast from the chest wall. By combining these measurements and adding in the findings from your exam such as nipple position, position on the chest wall, irregularities of the ribs, etc., your plastic surgeon can determine if you need two different size implants to... more

Minimal difference

We are talking about a 2mm difference between the two breasts, assuming the measurements are completely accurate. This difference is really not noticeable, and I would wager that you were not even aware there was a difference until it was pointed out to you. So, unless there is a concomitant significant volume difference, I would recommend the same implant be used on both sides.

Sizing Breast Implants When Breast Width is Not the Same

From the information that you have provided it is likely that you do not need to use two different breast implants. There is additional information needed to make a final decision. For example are you breasts otherwise equal in volume, shape, projection? If so, then you probably don't need different size breast implants. A thorough evaluation and discussion with your board certified plastic surgeon will help you to come to an informed answer to your... more

Breast Augmentation - If One Breast Measure 11.7 and the Other Breast Measures 11.9. Should You Use Two Different Sizes?

While I do not hesitate to use two different sized implants when appropriate, it's more a question of overall breast size than any specific measurement. Are your breasts noticeably different sizes? Most women's are, so achieving perfect symmetry is neither practical nor likely. If they are different enough in size then different sized implants should be considered; though, with the understanding that even if the volume is the same, having a much larger implant in... more

Breast asymmetry

I think you should stick with the same size implant, unless the breast are very different. Everyone has asymmery and it is impossible to match them exactly.

Breast asymmetry , implants and augmentation

This is a very small difference. other factors include chest shape and size breast volume differences and saline vs silicone. all of these factors need to be considered together

Different Breast Implants For Asymmetry

Using two different implants can accomplish improved symmetry in patients with significant breast differences in a number of characteristics such as breast volume, breast width or chest wall differences. Based on the sole measurement you provided (breast widths of 11.7cm / 11.9cm), assuming the other characterisitcs are relatively symmetric, I would NOT use different implant sizes. If, however, other asymmetries exist then I would certainly consider two different size implants to... more

When to use different sized implants

Breasts will always be a little assymmetric no matter what you do. They are not the same before and won't be the same after. So if you can't get them exactly symmetrical, then in general, it is best to use similar sized implants so that you don't make them more uneven, which is possible. The only times I recommend using different sized implants are if the difference befores surgery is greater than a cup size. By using a larger implant in the smaller breast... more

Concerns about breast asymmetry and the need for 2 different breast implants

Most women's breasts have some inherent asymmetry. The 2 mm difference in base width that you measured is negligible and is well within the limitations of measuring. This alone would not justify the insertion fo 2 different sized breast implants. If your breasts were signficantly different in size or projection then 2 different implants may help correct some of the asymmetries. Ultimately, I would leave any decision for the ultimate implant size or style - with your surgeon (of... more
