This surgery usually takes about an hour to complete under general anesthesia. The most common way to augment the breast is by inserting an implant under the pectoralis muscle by making a small incision in the crease of the inframammary fold.
Often the incision is made below the breast, but it can also occur either around the areola or in the armpit. The incision site can vary from person to person for many reasons, including your body shape and the size of the implant.
