Dr Dave Rosser said that Malala's recovery is "first and foremost" testament to her "desire to get better and her strength".
He said that she is not "naive at all" about the fact that she is a high-profile patient and that she remains a target for some.
He added that she is a "remarkable young lady" and described her as "very lively" with a "great sense of humour".
Speaking for the first time since her attack by the Taliban, schoolgirl Malala Yousafzai said she wants every child to be educated.
Doctors have said they plan to carry out two procedures to reinforce Malala Yousafzai's skull and to restore hearing to her left ear.
