When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer. ..
