Researchers from Sechenov University were able to print on a 3D printer a eardrum made of living cells and collagen.
To repair the perforation of the eardrum, we decided to create new and more complex tissue engineering constructs for us. We based on previously developed bio-inks containing biocompatible hydrogel and cell spheroids. Then, using a 3D bioprinter on biopaper, which were collagen matrices, we printed constructs.
Millions of people worldwide suffer from eardrum perforation, which leads to deafness or hearing loss. The new technology will allow people to regain their hearing within a month. Moreover, with it, the operation will be much faster than usual - about 40 minutes.
The researchers have already conducted experiments on chinchillas (their eardrum is very similar to the human one), there are plans to conduct clinical trials.
