Russia According to the Sechenov University located in the capital of Moscow Scientists has devised a method of bioprinting the eardrum with the help of living cells and a protein called collagen.
Researcher Polina Bukimulina said in a statement that thanks to the new technique, hearing-impaired people would be able to ‘hear again within a month’.
Previously, the scientists of Harvard University in the United States brought to the world the method of restoring hearing in three months.
In order to restore the eardrum, scientists decided to create a new and more complex tissue, said Polina Bukmolina, a junior researcher at the Institute of Regenerative Medicine, Russia’s state news agency Ria Novosti reported.
The scientists used prefabricated bioluminescence, which included hydrogels capable of interacting with living cells and 3D cells, as the basis, he said.
According to Prof. Valery Svetshkin, Director of the Clinic for Ear, Nose and Throat Diseases of Clinical Hospital No. 1 of Sechinov University, deafness and hearing loss are a common problem and a major challenge for specialists.
He explained that the problem of eardrum hole affects millions of people worldwide.
This leads to hearing loss and therefore the ability to perform occupational and social routines and quality of life.
He said that the new technology makes the process of helping people with deafness much easier, thanks to which the operation process will be done many times faster than the usual, which will take 40 minutes.

The university press service added that experiments are currently being conducted on a type of mice because their ear membranes are very similar to humans.
Later there will be a clinical study, after which it will be the turn to cure deafness in humans.
According to Harvard University’s website, the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Massachusetts Eye and Ear (MEE) developed a device called a phonograft with the help of a 3D printer. It can be used to restore the affected skin.
If successful in clinical testing, phonograft technology could be used commercially to reduce pain, fluid leakage and hearing loss caused by perforations in the eardrum.
Millions of people around the world are affected by eardrum disease.

**Interview with Polina Bukimulina on Advances in Bioprinting Eardrums**
**Interviewer:** Thank you for joining us today, Polina. Your recent research at Sechenov University in Moscow has made headlines. Can you explain the significance of your bioprinting technique for eardrum restoration?
**Polina Bukimulina:** Thank you for having me. Our method of bioprinting the eardrum using living cells and collagen is a significant step forward in regenerative medicine. We believe that this new technology can provide hearing-impaired individuals with the chance to hear again within a month, which is a major advancement compared to previous methods.
**Interviewer:** That’s remarkable! How does your method differ from the techniques developed by researchers at Harvard University?
**Polina Bukimulina:** The key difference lies in the complexity of the tissue we are able to create. While the Harvard method allows for hearing restoration in three months, our approach focuses on generating a more sophisticated tissue structure. By utilizing prefabricated bioluminescence integrated with hydrogels and 3D cells, we can effectively interface with living tissues, which enhances the healing process.
**Interviewer:** You mentioned that millions of people are affected by eardrum holes and the resulting hearing loss. Can you elaborate on the impact this condition has on people’s lives?
**Polina Bukimulina:** Absolutely. Deafness and hearing loss can significantly hinder an individual’s ability to communicate, work, and engage socially. It’s a leading challenge for specialists in the field. Our aim is not just to restore hearing but also to improve patients’ quality of life and enable them to fully participate in their communities.
**Interviewer:** Given the promise of your research, what are the next steps for this technology?
**Polina Bukimulina:** We are currently in the process of further testing and refining our techniques. Future clinical trials will be essential to ensure safety and effectiveness in a larger population. Our goal is to eventually make this technology accessible to those who need it most.
**Interviewer:** Thank you, Polina, for sharing your insights. It’s exciting to see such promising advancements in medical science.
**Polina Bukimulina:** Thank you for your interest! I hope to share more good news as we progress with this research.
