An ear, unsurprisingly, is difficult to make from scratch. Ear cartilage is uniquely flexible and strong and has been impossible for scientists to reproduce with synthetic prostheses.
If a child is born without one, doctors typically carve a replacement ear out of rib cartilage, but it lacks the wonderfully firm yet springy qualities of the original ear. And it often doesn't look so good.
