3D Printed Ears

A group of researchers in China has constructed ears for children suffering from microtia, a congenital condition where the external ear (pinna) is underdeveloped, with the help of 3D scanning and 3D printing.

The scientists, from Shanghai Jiao Tong University, the National Tissue Engineering Research Center of China, the Chinese Academy of Medical ScienceWei Fang Medical College and Dalian University, engineered a patient-specific ear-shaped cartilage in vitro using a 3D printed biodegradable scaffold and Microtia Chondrocyte (MCs) cartilage cells.

Microtia can have a negative impact on the hearing and wellbeing of children affected by it. Established procedures to treat microtia include rib cartilage reconstruction, plastic implants or prostheses.

Projects like Australia’s FutureHear are 3D printing customized ear molds, while Dr. Ken Stewart of the Royal Hospital for Sick Children in Edinburgh has used 3D scanning and 3D printed models to prepare cartilage reconstructions accurately in the shape of an ear.

This approach, however, combined 3D printing with in vitro tissue engineering on children suffering from microtia only in one ear.
