Well, this is a question that comes up once in a while.
Usually the woman in question will come in, and when I ask her what she would like her breasts to look like, she will cup her breasts and lift them up on the chest wall. This will cause a lot of fullness on the upper pole of the breast.
If this is what you mean, yes, an implant is the only way to do this.
What we refer to as a lift is lifting the position of the nipple on the chest wall, and tightening the skin envelope so the breast looks more youthful. It will not give that fullness in the upper pole that some patients want. It is for THAT fullness or "lift" that people recommend an implant.
