Ways to Correct Internal Scar Tissue in Cheek?

I got the scar tissue in my cheek (from wisdom teeth extraction that got infected) 4 years ago, I had lots of massages to manage the swelling but it still feels 'funny' and restricted Does anyone know about alternative treatments like injections? I was considering facial liposuction for the areas that feel bulky/restricted (right beside my nose down to my mouth) but I'm not sure how much of it is fat, the majority is probably tissue/muscles etc?
