If you find an alarm there, tell the security inspector that you have had surgery before, and there should be some scars after the operation. The position of the security inspector's chin will be known. If there is no scar, it is best to open a certificate of steel plate implantation in the hospital. That's no problem.

There won't be too much metal implanted in the jaw fracture, which should not lead to the alarm of the safety door.

I haven't been abroad, but it is common to implant metal in the body at home and abroad, and I see it every day.

Don't worry, no one has ever delayed a plane because of the operation of implanting steel plates.
