How to Approach the Subject with my Surgeon and Ask for a Revision Rhinoplasty?

I had septorhinoplasty 8 months ago & I am unhappy with the results. I have a bump on one side of the bridge of my nose & the other side feels significantly more shaved down, resulting in my profile being concave one side & convex from the other. This bothers me greatly. I am somewhat nervous to bring up the possibility of a revision with my surgeon as I do not want to offend. But I do feel a revision is necessary. Please advise as to how I should approach the subject and ask for a revision.
