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

I had ONLY a deep plane facelift revision and now my right cheek is dented, flat, and lumpy. The dents exacerbate upon smiling (photo). Surgeon says this is fat atrophy due to revision surgery. (I don't think this is possible since I saw this issue immediately after wrap removal.). Could sutures be too tight in my muscles or some other type of damage?? What could be causing this and what would you suggest to fix this issue ?? (I haven't had any fat transfers done. Only deep plane facelift)
