|China researchers construct artificial ears using 3D printing and tissue engineering|
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 Science, Wei 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 and 3D printing
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.
