Breast augmentation. Is the difference between Sientra high profile 330cc and 350cc noticeable? 105-107 lbs, 5'3"

Thank you for your question. There is a small difference between the 330 and 350cc implants. "Tissue based planning" relies on your chest and breast measurements and is the safest way to ensure good long term results. Your surgeon should determine what size and projection are necessary to give you your desired result based on your body's measurements. The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic breast surgery. Hope this helps and good luck with your surgery.

Hello and thank you for your question. Honestly, a formal in-person evaluation would be needed to determine the best treatment. There are several reasons for this:
1) Bra sizes vary based on the clothing store (for example, Victoria's Secret tends to upsize everyone by a whole cup size)
2) Most women do not wear the proper exact fitting bra size for their bodies
3) The exact volume (in cc) needed to change cup size is different for different body types (e.g. 32A to 32D requires a different implant size than 38A to 38D)
4) Be careful NOT to fall into the trap most women do- they see a certain implant size (e.g. 285 cc) or perhaps their friend had a certain size, and they want or request this or another size based on that. Everyone's body is different- 285 cc implants on your friend might look VERY different than they would on you. Be very careful not to make this mistake, because the goal is to find the right size and shape for YOU- for your particular body and your breasts.

Because of those multiple factors, and because it is KEY to fully evaluate your breasts in person to make a full set of precise measurements to select the proper implant for you (incorporating factors like amount of breast tissue, implant type, base width, projection, etc), answering your question really would need a formal personalized consultation- to say anything before that would simply be guessing, which would be both unfair and unhelpful to you. Also, just FYI, each surgeon's measurements are slightly different, so numbers, experience, and overall aesthetic from one surgeon aren't necessarily the same as those from another surgeon!

Your breasts are such a KEY area of your body and your femininity- therefore, you should ONLY trust an experienced aesthetic plastic surgeon. As such an expert, I have had extensive training and experience with complex aesthetic surgeries under a multiple world-renowned experts in the field. I’d recommend for you to setup a formal consultation with me (or another plastic surgeon who is extremely comfortable with aesthetic plastic surgery procedures) for a formal consultation to thoroughly discuss your surgical goals, undergo a formal examination, evaluate all your options (surgical and nonsurgical), and decide on the best procedure(s) and type of anesthesia for your specific case. I hope this helps!

The difference between a 330cc and a 350cc implant is 4 teaspoons, and is barely noticeable. If you are on the fence and are worried about being too small, pick the 350cc. If you are worried about being too big pick 330cc. But realize the difference is more psychological than physical. 

20cc is the exact volume of one tablespoon plus one teaspoon (or 4 teaspoons). Put this volume in a glass and try to imagine this amount over an entire breast making a difference. It would be like asking if 5 potato chips more or less would make a visible difference in a whole bag of chips. Even in the cheapo small size, you probably couldn't tell the difference; with the regular size and especially with the big bag, there would be no way to see this small difference.
The same thing is true here. Over a whole breast, 330 vs. 350 is an invisible difference. That is why implant companies manufacture implants in 30cc or larger increments--this is well BELOW the threshold of visibility!
I think with your size and weight, implants in this size (either one) will add about a cup and a half to your present size. You might expect a B to C cup result, depending on where you buy your bras. This will yield a nice, natural, and still sleek, feminine look, IMHO. Best wishes! Dr. Tholen

No. A 20cc difference is not a large amount. For your reference, 1 tablespoon is 15cc so both implants should look similar. I would not expect a noticeable difference. Congratulations on your upcoming surgery.
