I had an upper lip lift which resulted in a gap or "key hole" in the middle of my top lips. But if you see the before picture it is clear that I naturally had a little gap. I tried to fill the gap in the middle with lip filler. However the filler didn't stay there it moved as she was filling the gap. So I'm still left with very un even lips due to the gap in the middle. I wanted to know the exact procedure a plastic surgeon could perform fix/fill this gap?
