Open Question: rhinoplasty.... and insurance?

I broke my nose about 7 years ago. And, i went to an ent and they straightned out my nose and i under went surgery anestesia and all. Im not happy with the way it looks. On the bridge of my nose there is a raised spot where cartlidge is raised. I was wondering how i could get my insurance to pay to fix the problem. I want them to redo my nose basically like a nose job. I heard that it is possible forban insurance to pay.... do u have any ideas on how it works... thanks
