Which procedure would minimize the appearance of dents in the forehead? (photos)

I had surgery done last year April so it’s been over a year. The first 6 months I didn’t notice it but since my swelling has gone down I’m left with a major deformity in my forehead. I’m very unhappy with it and I’m worried about having a revision because I still have numbness from my last surgery, I don’t want to make it worse. What are my best options
