Each breast augmentation surgery is as unique as each patient on which we perform it. Deciding whether to have your implants placed over or under the pectoralis major muscle will largely be determined by: Your implant type (saline or silicone) The shape of your implant (round or teardrop) The size of your implant The amount of tissue your body has to cover the implant Your individual body type There are benefits to each type of placement, whether you and Dr. Bierly decide to place the implant over or under the muscle. Placing the implant under the muscle can provide a more natural shape to the breast. The thickness of your skin is also a factor in considering where to place your implant. Women with thinner skin may have better a better outcome when the implants are placed under the muscle. Implants that are placed over the muscle will move with the contraction of the muscle itself. This placement can allow for a lift in patients whose breasts have begun to sag or droop. As your breasts begin to age, implants placed over the muscle will naturally move into place with the rest of your body. And recovery is generally quicker and less painful when they are placed over the muscle.
