Bad Scar Tissue Remains After V-Y Lip Lift 8 Years Ago, What Are my Options?

Had a V-Y lip advancement 8yrs ago. I have a class 2 malocclusion/overbite which made the result exaggerated. My lips are uneven due to a chunk of scar tissue on the right side of my upper lip it's pushing the lip out even further.I've since developed a bad habit of grabbing the chunk of scar tissue/flesh with my teeth.I want it removed! The V-Y has also left my lip with a very flat & unnatural look. I tried the steroid injections, they did not work for me. What are my options?
