Ear with polymer ribs: scientists find a way to prevent implant deformation
Russian scientists have for the first time recreated the natural biomechanics of the ear in an implant produced using a 3D bioprinter.
The bioprosthesis not only replicates the external shape of the auditory organ but also mimics natural tissues through its composition. The researchers successfully combined a polymer framework with a soft hydrogel containing living cells — something that had previously been impossible due to the limitations of 3D bioprinting. In vivo tests confirmed that the implant develops a vascular network and successfully integrates into the body.
Biopolymer constructs printed using a 3D bioprinter avoid these drawbacks, but after implantation they often become deformed under the pressure of contracting skin.
To improve implant integration after surgery, specialists from NUST MISIS, together with colleagues from the National Clinical Research Center of the Federal Medical and Biological Agency, the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology, the E. I. Chazov National Medical Research Center of Cardiology, the N. N. Priorov National Medical Research Center of Traumatology and Orthopedics, the Institute of Plastic Surgery and Cosmetology, the biotechnology company Imtek, and 3D Bioprinting Solutions developed a hybrid 3D printing method.
