What can be done to correct the appearance of dented, flat, lumpy cheeks after deep plane facelift revision? (photos)

Hello,
With revision surgery there are a lot of variable. What you see maybe scar. It could be old filler in your cheeks if you have a history of injectables usage. It could be delayed swelling resolution as you did not indicate how many months it had been since surgery. If you are 6+ months postop the chances of unresolved swelling are much lower.
All that being said, it is clear that you have normal facial asymmetry and that cheek is clearly just smaller than the other said causing indentation when you smile and activate the muscle in that area (zygomaticus m.).
In any case the most natural option is to place micro fat injections into the area to gently inflate the hollow.
I hope this helps.

To fix the indentation, the best option is fat grafting (own versus off the shelf). Another option may be fillers to the area to make sure you are happy with the outcome prior to fat grafting. There is no way to tell at this point if the suture was too tight but the volume is the issue to help curve out the upper outer cheek.

Either there is bunched up deep tissue under the skin or the skin was not adequately separated from the underlying tissue. If it doesn’t go away after six months I would get a revision

You were correct the muscle deep plain tightening was done in effectively over aggressively. Might only consider with small pickle for release of indentation. Best of virtual consult with fees range from $5000-$15,000.
