Do I need buccal fat removal following a wisdom teeth removal? (photo)

I always had chubby cheeks, like a chipmunk. I have been always on diet, trying to lose weight, hoping that the fat on my face will go away. I considered buccal fat removal surgery, but I read that there are risks, so I let go. Following removal of all my wisdom teeth, my face shape has changed. It is now more chubby, more chipmunk like. It's been almost a week, and I am not seeing any change. Should I consider surgery? I am 5'7"/154lbs
