Saline Implants Breast augmentation, or augmentation mammoplasty, is one of the most common plastic surgery procedures performed today. Over time, factors such as age, genetics, pregnancy, weight changes, and gravity can cause the size and shape of the breast to change. Women who are dissatisfied with the size of their breasts or have experienced changes in breast appearance can achieve fuller, shapelier breasts with breast augmentation. During this process, breast implants are placed inside a pocket behind existing breast tissue. Breast augmentation can increase or balance breast size, restore breast volume, or restore the breast shape after partial or total loss. It is important to realize that breast augmentation cannot correct significantly sagging or drooping breasts. In these instances, a breast lift is often necessary, which may be performed in conjunction with this procedure.
