Looking to do a revision.. How much of a difference is there between 545cc and 595cc silicone for a patient of my frame? (photo)

Had 425 cc silicone, mod+ implants placed under the muscle, putting me at a very small 36D. I LOVE my surgeon's work, just unhappy about my size which I chose. was looking to be a solid D, to balance my larger lower body. I stand at 5'6". 157 lbs. 42" hips. 29" waist. Sizers were extremely inaccurate for my body. Want to go up at least 150 cc's but there's no size in the 570cc range, so I want to know if there's a significant difference between 545cc and 595cc for someone of my frame?

Increasing Breast Implant Size by 50 CC's

A small change in CC's may not be drastic enough to notice a significant size increase. Depending on the reason for the breast revision determines the sizing outcome. However, there are no guarantees with size predictions for revisions. Initially, if a woman wears a size 36 AB bra and would like to be a C cup, which is the average size that women wear and the average size bra that is sold, she needs a volume of approximately 350 to 390 cc to make that change. This becomes less if she's wearing a 34 bra, because it has a smaller strap size and the cups have a smaller diameter. A smaller diameter implant would then be a volume of approximately 300 to 350 cc. In the same way if she was more petite, maybe a double zero or size one and wore a 32 AB bra, then to become a 32C cup she would only require about 250 to 300 cc. This is a general number, and of course there are other factors that will affect this. 

Other factors which contribute to the outcome are #size, #shape, and #profile.  The #profile is determined by the amount of #projection versus roundness that the you desire, as well as the #size of the implant and size of your chest. Also, the placement or incision location will also have an effect on profile. 
Another element to a satisfying result of your #augmentation is realistic #expectations.
#Shaped implants are all #textured and should not rotate when used properly. In my practice, about 20% of the patients benefit from shaped implants. Your Plastic Surgeon needs to measure you and determine the best shape and size of any implants that are used.

What is a noticeable difference in implant size?

Our general rule of thumb is that 100 cc's is a noticeable difference, whether going larger or smaller, but there are obviously a lot of variables. Confounding the issue is the inadequacy of the cup size system, which is only partly related to breast volume. Once you get into the large implant range, problems are more common so keep that in mind. You may benefit from a 3D analysis with VECTRA or similar technology to help visualize the possibilities.

Larger implants will not solve your problem

At size 36 each 200 cc’s of implant corresponds to 1 cup size change. From your photograph, it appears your breasts are asymmetrical with approximately 100 cc’s difference. You have undergone a Wise pattern lift and your implants have extruded inferior to the muscle. Larger implants will result in more extrusion, displacement and will require revision. I recommend a new technique called The Mini Ultimate Breast LiftTM. A circumareola incision is used to reshape your breast tissue creating upper pole fullness, elevate them higher on the chest wall and more medial to increase your cleavage. Aligning the areola and breast tissue over the bony prominence of the chest wall will maximize the projection of the implant. This technique uses smaller implants then you have now or slightly larger to correct asymmetry on the smaller side. Simply going to larger implants will not fit and you will require a revision.

Looking to do a revision.. How much of a difference is there between 545cc and 595cc silicone for a patient of my frame?

Thank you for the question and picture.  The difference in volume and “clinical difference” between the breast implant sizes you mention will not be very significant.

Generally speaking, the best online advice I can give to ladies who are considering  breast augmentation revisionary surgery ( regarding breast implant size/profile selection) is:

1. Concentrate on choosing your plastic surgeon carefully.  Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you're looking for. Ask to see lots of examples of his/her work.

2. Have a full discussion and communication regarding your desired goals  with your plastic surgeon. This communication will be critical in determining which operation and/or breast implant size/type/profile will most likely help achieve your goals.
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "C or D cup" etc means different things to different people and therefore prove unhelpful.
 Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.

3.  Once you feel you have communicated your goals clearly,  allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals.  Again, in my practice, this decision is usually made during surgery.

I hope this, and the attached link, helps.

There are implants in the 575cc range in moderate (+) with Mentor and 545 and 595 with Sientra. Obviously the diaameters of the implants are different and one would need to examine you to see what would work. The diameter of your present implant is very close to the HP implants from Sentra if that is any help Dr. Corbin

Is there a difference between 545 and 595 cc implants?

I would tell you there is very little difference, if you are currently unhappy with your 425 cc implants I would recommend increasing the size to 595 if they fit your frame and base width, we find most women 3 months after surgery wish they would have went a bit larger. Good luck!
