Is my genioplasty bone position too high? (Photos)

Hi. I had a sliding genioplasty 8mm 3 years ago and I’m suffering from lots of tightness, mostly in the fold area of the chin and lower lip. Very tight, stiff and feels like it has little room for movement. Could this be due to the bone position? Is it too high causing the tissues to be compressed? Or is it more to do with scar tissue / adhesions perhaps? I’m desperately trying to find answers and a solution but nobody seems to know. Thank you
