Each year around 100 children are born in Britain with one or both of their ears missing, a condition called microtia.

BBC News was given exclusive access to treatment at London's Great Ormond Street hospital, where doctors create new ears, and graft them onto the head.

Kieran Sorkin is one young patient who has benefited from the technique, as Fergus Walsh reports.
