A 64-year-old man who was blown half his face in a hunting accident is the oldest person in the world who has had a full-face transplant.
Maurice Desjardins, of Gatineau, Quebec, needed his jaws, teeth, lips, nose and face muscles and nerves to be replaced in the extraordinary 30-hour operation.
A team of 100 doctors carried out the great surgery and Mr. Desjardins can now eat, talk, breathe and even smell with his new face.
Doctors said the operation was the last chance to restore a normal life for Mr. Desjardins, who lived in constant pain for seven years after his accident.
The surgeon who performed the transplant became the first in the Commonwealth to make the operation extremely rare: only 40 face transplants have been performed in the world since 2005.
Health officials said they were "very happy" with the transformation and the surgeon, Daniel Borsuk, said he offered "immense hope" for his patient.

Mr Desjardins' life-changing operation was carried out at Hôpital Maisonneuve-Rosemont in Montreal in May last year.
He became the oldest person in the world to receive a face transplant, thanks to Dr. Borsuk and TransplantQuebec.
Mr. Desjardins had to pass years of tests to prove that he was fit for the transplant and mentally strong enough to cope with the change.
The procedure has given him a new lease of life after spending years breathing through a hole in his neck, and it is difficult for him to talk, sleep or eat properly due to his devastating injury.
Social interactions and going out in public became difficult for him because he was so disfigured, which led him to spend a lot of time alone at home.
The doctors said that Mr. Desjardins is a "natural extrovert" and that he had been living in the hope of returning to a normal life.
And now, thanks to the work of a day and a half for nine surgeons, Mr. Desjardins has regained the ability to breathe, eat, talk and smell with his new face.
The chief surgeon, Dr. Borsuk, said: "As a plastic surgeon, I know that, no matter how large or small, the injuries on the face look particularly symbolic and are closely related to our identity.
"Facial disfigurement can have a detrimental effect on self-confidence and productivity, and therefore, this transplant offers an immense hope and possibility for our patient."
Mr. Desjardins had to breathe through a hole in his neck because his face was disfigured and he lived in constant pain before his operation that changed his life last May.
Dr. Borsuk has experience in repairing huge facial injuries, working on another man with a gunshot wound in 2012 and recently rebuilding someone's face with part of his pelvis.
And despite the complexity of transplanting one face to another person, the operation is cheaper than performing numerous operations to repair the injuries.
Dr. Borsuk told CTV News that Mr. Desjardins wanted to be able to go out with his granddaughter without being stared at.
He told the news station: "Imagine when you are suffering in silence in your house for years and do not leave your house as much as you would like.
& # 39; You are living this very difficult existence. Then, overnight, in essence, you get a second life.
"It's so mentally tough that even with everything that was done, it started [accepting] the new face That's something we were telling. "
Transplant Quebec provided the new face of Mr. Desjardins after obtaining permission from the donor's family.
The managing director Louis Beaulieu said: "Transplant Québec is very pleased with the success of this, the first face transplant in Quebec and Canada, possible thanks to the donation of organs
"We would like to thank the donor family, who showed great empathy and generosity in accepting that their loved one donated their face and organs.
"The tremendous collaboration between Dr. Borsuk and Transplant Québec's team is one of the keys to the success of this first one, which was so beneficial for the recipient."
