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

It should be fine for you to have lip filler while under anesthesia for your breast augmentation.  Be sure to discuss your desired outcome with your surgeon since you will be asleep during injection.  Best wishes with your surgery!

I believe this is a safe combination to perform more comfortably under anesthesia. I don’t believe it will affect your overall results!Best wishes. Dr. Aldo

For GA you will most likely have an endotracheal tube or LMA placed to help you breath while asleep. These tubes can distort the contours of the lip and may make it challenging to judge the final appearance from the injection. I would recommend having it done awake if possible but asleep is also feasible. Good luck!

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.
