Will 400cc Silcone Implants Be too Large for my Body Size?

Hi,I have saline breast implants now at 270 left breast and 300 right breast.I am getting them redone but am at the stage where I have to decide the size.I have done the rice test and added 100 cc more to what I have and can not really see the difference, but I know there would be. I am 5ft 0in and 120 pounds and rib cage is 33.5 around. Can you tell me if 400cc is to large for me to go with silicone implants.Do silicone lay the same or do they appear smaller after inserted under muscle.

Changing from saline to silicone breast implants

A rule of thumb when changing from saline to silicone breast implants is to increase the size by 100cc. This is because of the way the implants are made. Saline implants are inserted empty and then filled. When they fill, they take on an oval shape. Silicone implants are inserted filled. They are manufactured in the shape of a half-oval, with a flat base. The flattened base accounts for the increase in volume necessary to match that of a saline implant.

Implant Size

In my opinion, silicone implants appear smaller than similarly sized saline implants. In addition, most studies indicate that for a patient to "appreciate" an increase in implant size, 150-200cc needs to be added to the existing implant volume. This of course varies based on patient size and anatomy.

Breast implant sizing

It is very important to communicate your size goals with your surgeon. 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 cup” or "fake looking" 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... more

Increasing the size of the implants may be possible. There are different profiles and the base diameter of your breast will determine what size implatns will fit on you chest. Silicone implants of the same volume do tend to look a little smaller than comperable sline implants. Good luck

Picking the "right" implant for you.

I consider two factors when selecting implants for my patients: 1.Dimensional planning 2.Gel Implant Sizing system Dimensional planning – The measurements of your chest wall are taken. Also, the breast dimensions including the height, width, and current dimensions of each breast form the basis of dimensional planning. Based on these measurements, the implant size is recommended. This will give you a unique breast implant that is suited for your body frame. Even your... more

Too large of implants

Yes, with your height and weight, 400cc of any implant would be too large and may cause problems in the long run.

Breast Implant Sizing

Prior to deciding on the right size implant, your surgeon should evaluate the width of your chest wall and the breast tissue and overlying skin envelope. I believe a high profile gel implant carries similar projection to a moderate plus saline projection. In addition to implant size, I would consider going with a higher projection. Assuming your chest wall width and skin envelope will accept a 400 cc implant, you can expect a cup size increase with... more

Changing implants

Without an exam it is hard to say but if you are looking for more volume, you would need to probably add between 150-200 cc'sat least to see a cup change.

Increasing breast implant sizes - C cup

If you are undergoing primary augmentation and had little breast tissue then a 400cc silicone prosthesis would certainly make you at least a full C. It would be helpful to know with your present implants what the end fill volumes were, since that will have an effect on how much a change the 400cc prosthesis will create. In my experience, silicone prosthesis of equal volume appear somewhat smaller than their saline counterparts. So that if for example, the right 300cc implant had been filled... more

Breast augmentation

Please be careful about placing too large of an implant. The price that your tissues will pay in the future may not be worth it. 400 cc for your frame sounds a bit too large, but this is without seeing any photos.
