War not only kills people, but also disfigures them. After World War I, Harold Gilead set up a plastic surgery team in England to treat the terrible facial injuries suffered by many soldiers. He was the first plastic surgeon who tried his best to restore the patient's normal face. 1932, he hired a New Zealand surgeon, archibald MacInto, as his assistant.

The Second World War brought a new form of casualties. The hand and face of the pilot who was shot down were burned. Mcgindo transplanted skin from other parts of their bodies to the burn site. He tried to repair their faces. These people must endure the pain of surgery for several years. A patient complained, "We are no longer pilots. We have become an experiment for plastic surgeons! "

McIntyre's patients formed a group they called "Guinea Pig Club". Soon, the club has more than 600 members from 16 countries.

Since then, this technique pioneered by MacIntosh has been applied to other severely burned patients.

The severity of burns depends on the depth of burned skin. First-degree burns only involve the surface layer of skin, second-degree burns involve the dermis below, and third-degree burns involve the whole skin. New skin can only grow from the edge of the wound, so extensive burns require skin grafting.
