Would I See a Difference Going from 375 Cc to 500 Cc? (photo)

Thank you for your question.

Of course going from 375cc to 500cc implants should make a difference.  Will it meet your goals? It's hard to tell without an examination and some goal photos.

Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.
I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. 


Increasing your current implant #size may cause #sagging. Typically, to increase implant size the #pocket will need to be adjusted and a #breast lift may be necessary; to better #support the weight of the implants. However, it is possible that the #pockets may need to be adjusted. Creating a #Neopectoral #pocket is sometimes used as a technique to provide a stronger more secure placement for breast #implants. In this case, the implant is removed and the capsule is dissected from the muscle to create a new or “neo” pocket for the implant. 
Your implants may need to be re-positioned. It's best to begin by consulting with a board-certified surgeon in-person to learn of that is in fact the case, and, as to which approach and implant #type is most ideal for you.
The best #option for #revising should be discussed during a one-on-one consultation with a board-certified plastic surgeon. Deciding on additional #elective cosmetic #surgery is a personal #choice. Your procedures should always be performed by a #PlasticSurgeon who is board-certified and has a great deal of experience specializing in cosmetic #surgery. 

The increase in volume will make your larger but if done alone would simply make your implants even higher. I agree that the muscle may have not been released in the first surgery and that is contributing to the 'high' implants. Your revision should include a full muscle release and you should consider an anatomic or 'tear drop' implant as your nipple to breast crease is very short. This will help to decrease your upper pole fullness.
