Is there any real difference between 320 and 350 CCs?

The difference between the two implant sizes is nominal. My best advise would be for you to try them both out and see which one looks better. My best,

 Thank you for your question. Often times my patients find themselves in the exact same position ---- debating between two sizes which are very close together. I recommend that my patients go ahead with the larger of the two sizes. This advice has proven to be reliable for both my patients and I. Best of luck.

There is minimal noticeable difference + or - 30 ccs.   It is certainly very normal for patients to be concerned about choosing the correct size,  generally speaking in my experience if there is a post op discussion about size more patients wish they'd gone a little larger as opposed to smaller.    We have "sizers"  in the office for  patients to "try on"  with different shirts this can be very helpful.  Yes I would expect your surgeon to overfill saline implants,  if yourconcerned about rippling you may want to consider cohesive gel implants.      Discuss your concerns with your PS you want to beconfident with your choices prior to surgery.    Good Luck
