He had a wound on its skull because he was receiving the cancer treatment. The Transplant was carried out by the MD Anderson Cancer Center and Houston Methodist Hospital doctors. Not Only his skull is new but he has also received new pancreas and kidney. Surgery was 15 hours long and 60 medical professionals were present at the time of transplant.
He has fully recovered from the surgery and now he will be released soon but he will have to learn to walk because after staying for too long in the hospital he will face difficulty in walking. In this case doctors have transplanted tissues with blood vessels , nerves and bones so they are now aiming to transplant more complex organs like face and hands.
