The most common procedures are kidney and liver transplants, followed by heart transplants. However, doctors in Baltimore and elsewhere have successfully transplanted other body parts from deceased donors to living candidates.
In January of this year, a Frenchman became the first person to receive a second face transplant. Jerome Hamon received his first face transplant in 2010, but it needed to be removed last year after Hamon became ill.
Hamon's first face was donated by a 60-year-old. With his second transplanted face – from a 22 year-old donor – Hamon, 43, joked that he managed to drop a few decades.
France was also the first country to be site of a face transplant. The procedure has since been performed several times in Baltimore.
In 2012, doctors at the University of Maryland performed the most extensive face transplant at the time on a Virginia man named Richard Lee Norris.
Norris received donor skin from his scalp to his neck, as well as a new jaw, teeth, tongue and the underlying muscle and tissue. In addition to matching his blood type, doctors had to match his skin color and bone structure to a donor.
The University of Maryland has pioneered other transplant surgeries as well. In 2016, doctors at the University of Maryland Medical Center were able to perform a kidney transplant on a patient with no need for dialysis — a feat they said was the first type of procedure in the country.
It was a triumph for one of the transplant surgeons, Dorry L. Segev, who fought for six years for federal approval of the life-saving surgery.
Hayley Gorenberg, deputy legal director for Lambda Legal, a civil rights organization that serves the lesbian, gay, bisexual, and transgender communities and people with HIV, called the transplants a "triumph of science over stigma."

The controversial surgeon suggested that, contrary to accepted modern medicine, it's possible to repair a severed spine.
