Is there a big difference between the 270cc and 320cc Sientra round HP textured shaped implant?

Thank you for your question. A difference of 60cc can be small or big depending on who they are placed in. Ask your surgeon to provide more information. I hope this helps!

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 may or may not be significant based on your breast measurements. In reality it is less than 2 shot glasses of volume that you are talking about. Here is a more thorough explanation: It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 350 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in a bit.

A 50 mL difference is less than 4 tablespoons. This translates to a very small difference in dimension. Therefore, these implants are quite similar. I think the best way to evaluate this is by using sizers

The difference of 50cc's in an implant can be a difference.  It can be especially noticeable with a patient that has a smaller frame. Also depending on how much breast tissue a patient starts off with.  Most Surgeon's will do "Breast Sizing" at the time of your pre-op appointment to ultimately determine what size you are looking for.

Thank you for your question. Pictures would be helpful.The difference of 50 cc between a 270 cc and 320 cc can be noticeable, especially in someone with a petite frame.The most important determining measurement in picking the best implant is your breast base width diameter.To be sure, see two or more board-certified plastic surgeons in your area for a full and complete evaluation to make sure you are a good candidate and that it is safe for you to have surgery.I hope this helps.

The exact choice of size that will work best for you is an important decision that you should make with your board certified plastic surgeon. 3D Vectra imaging and simulation, the Mentor gel sizing system, rice filled implants at home in your bra, and bio-dimensional analysis are all methods that can be employed to help you come to a decision. Because size is such an important component of decision making in breast augmentation our office employs all of these techniques with each patient to ensure the highest rate of satisfaction possible. Good luck with your decision!

I think 50 cc's is a noticeable difference especially in smaller implants. You can do a baggy test to see the difference for yourself.

Dear Summer rose,The difference of 50cc can be significant if you are starting with very small breasts.  If you already have a fairly large amount of breast tissue, then 50cc is not a big difference.  Good luck!

50 cc is noticeable in small implants, but not in the normal to larger sizes.  Look at the difference by using the rice test.
