3 months post op Facelift, I still have swelling. Is this normal?

Swelling  3months after the procedures you describe would not be unusual. It is more unusual to have swelling that is on one side more than the other. If you tend to tilt you hear to the right while sleeping this could explain the difference in swelling between the two sides. Most importantly, you should be seen by your surgeon regarding your concerns.Good luck.Dr. Kaniff

It can take six months and sometimes up to a year to see resolution of swelling after surgical procedures on the face.  Pictures or an exam of you would be needed to determine if the amount of swelling on your right side is normal or not.  In general, swelling should be improving over time.  I would recommend contacting your surgeon so that your recovery can be evaluated.
