How did they get rid of Voldemorts nose?
As part of Voldemorts character, he was just made with no nose. As he grew and became more evil, his appearance had to become uglier, so they made him have no nose. To make the actor have no nose, they simply used make up and face putty to make the actor look as though he had no nose. The graphics of voldemorts "no noseness" gets better as the movies go on as better make up is being produced and so are special effects.
