Uneven cheekbones after failed cheekbone reduction in Korea 2 months ago, the doctor said it's normal. Can it be fixed? (Photos)

The left side is popped out. I went to see another doctor who suggest me to wait at least after 3 months to redo To my memory, the bone was popped-out right after the surgery. I just do not understand this failure cause it's a very careless mistake. I would like to seek more advice. (1.) The possible reason for this to happen? (2.) Is it fixable and when to fix it? (3.) When can I remove the screw/plates?
