Can you fill a big dent on your head even having a titanium part in your skull?

So I had a car accident 2 years ago and they had to remove a small part of my skull ont because of pressure in it but after a few months instead of putting my left skull back in they put a titanium part but caused a big dent in the left side of my head and it's hideous to see and i want to have cosmetic surgery and fillin the dent fully but I'm not sure if it's possible
