Volunteer US firefighter Patrick Hardison underwent the world’s most extensive face transplant surgery in New York on August 14, 2015.
Fourteen years earlier, when Hardison entered a burning home on a rescue search, the roof collapsed on him and his firefighter’s mask burned onto his face. 
He was left with disfiguring burns across his entire face, head, neck, and upper torso. He lost his eyelids, ears, lips, and most of his nose, as well as his hair, including his eyebrows.
