Can scar tissue have replaced the buccal fat causing swelling on right side?

I got a buccal fat removal a year in a half ago , and I have lumpiness from scar tissue that can be felt inside mouth on ride side of inner cheek , I also noticed that my right side of face is more puffy , but left side is good and has no scar tissue , can scar tissue have replaced the buccal fat causing swelling on right side ?
