LAM FACIAL PLASTICS

I have had 2 facelifts (the last one 1 year ago), so there is scar tissue along the sides of my face, and unfortunately, in the 2nd facelift, he sutured 3" from ear inwards below my cheek bones. I understand you can deal well with scar tissue. 2 questions: 1) The 3" suture line is tightly attached to the SMAS? underneath it. Would you tunnel UNDER the SMAS or dissect between skin & SMAS? Would it not show lumps?
2) How much is blood supply diminished in the areas where there is scar tissue?
The main outcome for me would be to fill in cheek hollows that are extensive, partly due to the weird suture line. Thank you!

typically, i have no problem tunneling under scar in the cheek or buccal area. however, a few inches within the skin surface incision line, sometimes it can be adherent and difficult to fill there. i would have to see you to be precise about what you are saying. worst case scenario, the fat will make the entire face look good minus the small area of concern, which could be handled by a filler.
best,
