Removing some of metacrill from my cheeks caused curve in my face. A doctor recommends to fill it by fat grafting. Is it safe?

I have a mixed skin. A doctor filed the lines with metacrill 10years back. But recently I removed some of metacrill due to deforming in my cheeks but it causes curve though metacrill was not removed totally. Now I really frustrated &dont know what to do . Some recommends to fill it with fat grafting other doc recoomeds facelift which reduce it. but I'm Afraid to get a bad results. What shall I do. Appreciate your advice to travel & see a professional doctor regardless of the place .
