Is There Something to Fix 1 Cheek Fatter Than the Other?

I had maxillofacial surgery for broken cheekbone now 1 cheek is puffy and sticks out farther than the other. The doctor said it was something like the fat separated or something and that it might go away. Well 5 years later it's the same. Would buccal fat removal make both cheeks look the same again or is there another procedure to fix it?
