Does implant size shrink after surgery?

The implants do not "shrink".  However, if they are under the muscle, they will appear a little bit smaller than they did when you tried sizers on at your consultation.  I advise my patients that if they are torn between two sizes, they should typically go with the larger of the two.  Good luck with your decision!

The implant will not shrink in size. Over the course of two months the implant will settle and the breast will take on a more rounded/teardrop shape.Unfortunately, online recommendations for implant sizing aren't helpful for you. Implant sizing requires an in person consultation where the surgeon takes measurements and get a sense of the look that you desire. All of this information is needed to pick the perfect implant and give you the look that you want.If there's ever any question, it's best to go back to see your plastic surgeon. They will be happy to discuss the sizes that you are considering.

you must add some volume (I found 10% to work well for my practice and patients) to what you like in your bra to achieve something close to the results you saw.  Using the same size you liked in your bra will result in a smaller appearance, regardless of whether you go above or below the muscle.   Your 325 cc size would increase to 360+ cc's.

Breast implant size does not change after surgery.  However, your breasts will tend to shrink some while healing because of swelling and settling of the implants.  Also, when implants are placed under the muscle they tend to appear smaller than expected.  I usually have the patient select a slightly larger implant to help compensate for this change.  

The difference in size between a 325cc implant and 350cc implant is very subtle. After surgery your breasts will be swollen and as the swelling goes down your beasts will appear smaller.  If you are unsure about the size I would recommend going with the 350cc implant if it fits your body.  I would discuss this with your surgeon.

No, implants do not shrink with time. Saline implants can leak and deflate, however. Your tissue will soften and let the implants settle, and the swelling will subside. I would suggest meeting with a board certified plastic surgeon and discussing all your concerns. During the consultation, you will be measured and see what range best suits your frame and tissue. You will also be able to try on a variety of sizes to see what you like. Your doctor can help guide you to the best size for you.

As long as an implant is intact, it will not shrink in size following surgery.  However, it is not unusual to have some moderate swelling or fluid build up around an implant in the first few days after a breast augmentation.  It may take a few weeks to see the final size and shape of the breasts following the augmentation.  A 25 cc difference between 325 cc and 350 cc is fairly small and the difference in appearance between the two implants should be minor.  Ask your surgeon for their opinion in you case.  best wishes, Dr. Lepore.

The only way an implant could get smaller would be if it was a saline implant that leaked. The thought that implants get smaller when in you as opposed to outside your skin in your bra is untrue. They simply gain width and lose projection due to the pressure of your muscle and soft tissue over them. That is why trying on implants and choosing on that basis is a flawed concept. The use of intraoperative sizers is the only real way to know what a specific implant will look lie once inside you.
