Deep Crease Left in Stomach after vaser liposuction - can this be fixed without a tummy tuck? (Photos)

I had vaser on 10th November 2022. I had a searing pain under my breasts when I woke up but assumed it was normal. On the two week check up when the compression was removed there was a deep crease in that area. I was told it was scar tissue that would flatten out. I follwed the post surgery instructions with massages. 6 months later the crease was still there, I was told it was still scar tissue and it was injected with cortisone. 1 year later it was still there, I was told that it was still flattening out. Its now 3 years later. It was injected with PBS (I think he said) which has loosened the scar tissue but the deep crease is still there and now Im being told I need a tummy tuck to fix it and I have to pay for that. Is there anything I can do to fix this that isnt so invasive?
