Face transplant 'double success' :

Successful results from two more face transplants will speed progress towards similar operations in other countries, say experts.
The Lancet journal reported operations involving a bear attack victim in China, and a French patient with a massive facial tumour had taken place.
The Chinese patient was given not just the lip, nose, skin and muscle from a donor, but even some facial bone.
Specialists in London are working towards the UK's first transplant.
Frenchwoman Isabel Dinoire became the world's first face transplant patient in 2005 after being savaged by a pet dog. She described the results of the operation as a "miracle".
The latest operations were just as complex, but involved different challenges for French and Chinese surgeons.
