Lip filler while under general anesthesia for BA, could it affect the results in any way?

Lip filler is done painlessly awake so I prefer patients see the results and assess their liking while awake so that feedback to their liking can be made to how they want their lips to be.  Therefore more patient control to what they want while awake versus under anesthesia.  

There is no health problem performing lip fillers during general anesthesia, or during a breast augmentation. One does not affect the other. I do believe, however, that you might have better results if you're awake, able to move your mouth and lips, and upright when the injection is performed. If you're unconscious and laying down, and maybe with a tube of some type in your mouth, it can be more difficult to judge just how much filler should be in each portion of the lip. It doesn't hurt much at all, so I'd recommend that you do the filler during one of your pre-op or post-op appointments.
