3D-printed human ear replicas created using tissue engineering techniques offer potential grafts for congenital malformations or ear loss.
Scientists at Weill Cornell Medicine and Cornell Engineering have created a 3D-printed replica of a human ear using tissue engineering techniques, offering potential grafts with well-defined anatomy and correct biomechanical properties for individuals born with congenital malformations or those who have lost an ear later in life. The replicas have flexibility and elasticity similar to human ear cartilage, but researchers plan to add chondrocytes to improve their strength and biomechanical properties.
