You may not be a candidate to move from B to DD Cup. There is a limitation on the size that can be implanted based on your anatomy.

The size of the implants are based on a combination of a patient's goals and objectives and her anatomy. In order to provide a natural looking augmentation, the surgeon needs to evaluate many factors including soft tissue coverage, skin laxity, chest wall width, breast imprint width, the shape of the breasts and relative level of constriction to ensure that the breast implants are appropriate for your body. Consult in person with 3 experienced and expert board certified plastic surgeons to understand your options.

Implant Selection Process

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Yes, there are anatomic limitations in implant selection.   The larger the implant, the higher the risk of complications. In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.

Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.

There are limits to what can safely be done.

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Yes, there are limits to how large an implant can be placed under and over the muscle for that matter. It all depends on how tight your skin, breast, and muscle tissue are. It also depends on the base diameter of your breast and width of your chest/rib cage. If you have a very tight breast pocket and are narrow chested, then you may want to get a reasonable sized and allow your body to heal.  You can then decide if at some point you want to go bigger.  This may not be advisable though.  It is known that very large implants have a greater chance of having long term complications. Discuss this specifically with your plastic surgeon.

Size limitations

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Yes, there are most definitely size limitations.

In general, it's important to match the implant size to the frame size of the patient.   But tissue tightness plays a role too.  So, there is a size limit.  Using an implant beyond this size could increase the risks of tissue thinning, pocket expansion, wound healing problems, future surgeries and revisions.  So, it becomes significantly riskier.

Is there a limitation to breast implant size??

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Your surgeon probably believes it is not in your best interest to go under the muscle with the size implant you desire.   Although possible, it may not be advisable.  The larger the implant is, the smaller the portion of that implant will actually be under the muscle.  A full profile globular implant windowshades the muscle superiorly.  If you have a low breast or a large skin envelope, the implant settles low, and will not be covered by much pectoralis.  Beyond a certain size, what's the point of elevating the muscle to put it over 10-25% of an implant??

Implant and under the muscle

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I could not say for sure t hat every single size of implant can go under the muscle. It really depends upon yoru soft tissue laxity and the sixe you want. The best way to know is to go for an exam and discuss yor goals with the doctor.  Good luck.

Implant size under the muscle

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
There is a limitation on how large an implant can be used. Your own chest width is important. Too large an implant will not only look odd but is more likely to produce complications, including extrusion and significant sagging. The goal in breast augmentation surgery should be to produce a natural appearing breast and not to set the patient up for problems down the road.

Breast Implant Size

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Breast implant size should be determined by your anatomy.  Not all implants can fit in all people.  The diameter of your implant is determined by the diameter of your own breast.    If you post pictures, we may be able to give you some general advice.  However an in person consultation would be necessary to give you specifics as you would need a complete examination and consultation.


Good Luck.

Implants under muscle-Size does matter

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Impants are only partly covered by the chest muscle when we place them behind the muscle. Your actual breast width defines what  size implant can be chosen This is a range of sizes that can be used. Our goal is to provide you with the proper dimension implant for YOUR chest area. Implants that are TOO large, have been shown to cause problems that are hard, if not impossible, to correct with additional surgery. This is true even if implants are placed on top of the muscle as well. Lastly, not all cups are created equal and I generally recommend that women choose a volume that fits their idea of what they hope to achieve, not a specific cup size. We have been using 3D imaging for the last year to help with the decision making process. I hope this helps and I wish you well with your exciting process!
