How Much Smaller Do the Breasts Look when Going from Overs to Unders?

I have Mod+ 325s silcon overs. My new implants will be unders. My revision is due to capsular contraction. My PS said they will look smaller under the muscle. I am 5'5", 110 lbs, 32DDs. I'd like to go down a cup size so I'm wondering if I should ask for a smaller implant although I would need a lift.

How Much Smaller Do the Breasts Look when Going from Overs to Unders?

For saline implants, I tell patients they will lose 10-15% of the volume and for silicone implants, I tell patients they will lose 15-20% of volume when transitioning from over to under.

Implant position

The actual volume of the implants are obviously the same but the look may appear slighly smaller under the muscle based upon the slope.

Size difference above and below the pectoralis muscle

Your plastic surgeon is correct. If you take the same size (dimension and volume) implant from above the pectoralis muscle and put it in a new pocket below the pectoralis muscle, it will look smaller. It will not actually be smaller but it will look as if it is. I would agree with Dr. Rand that it will look about 1/4 to 1/2 cup smaller. This is one of the difficulties with figuring the size and looks of a breast by putting implants or some filler in a bra externally. The same volume... more

Breast size will not change, over to under the muscle

The truth is that the implant and breast volume will be the same whether the implant is under or over the chest muscle. What does change is the profile of the implant. Under the muscle the implant may begin with a slightly lower profile, but this will balance as the muscle and breast relax to accommodate the the new shape. At this point there will be little difference. Capsule contracture is one of the biggest problems with 'perceived' volume of the breast. In the case of a... more

Under the muscle breast implants lose about 50cc of volume

By placing an implant under the muscle, you lose about 50 cc's of the look you get when they are placed in a garment. 50 cc's is about 1/4 cup size. So this is a situation where you and your surgeon would need to work out the details and get the look you want.
