Can surgical extraction of scar tissue fix my smile?

I've undergone two corrective surgeries to my left cheek implant entering through the left gum palate but the second surgery I got a year ago left massive scar tissue. I have a super hard lump in the spot of the surgical entry that feels like it extends upper wards as well. It has left me with facial asymmetry and my smile is now uneven. My surgeon recommended another surgical scar tissue removal but won't that just cause more to develop again? Is there anything I can do to restore my smile?
