A surgeon grafted a printed ear implant from human cells

An American medical team announced on Thursday (June 2nd) that it had for the first time grafted a human ear implant created from the beginning of the patient’s cells and treated with a 3D printer, a procedure that should be able to help people suffering from a rare birth defect.

This operation was performed in a clinical trial designed to evaluate the safety and efficacy of an implant for people affected by microtia, not the outer ear is not properly developed. AuriNovo, the name of the implant, was developed by the company 3DBio Therapeutics, and the operation was performed by Arturo Bonilla, founder of an institute specializing in the treatment of this malformation, in San Antonio, Texas. «As a physician who has treated thousands of children with microtia across the country and around the world, I am excited about this technology and it could mean something to patients and their families.”Said the surgeon, quoted in a company statement.

The procedure is performed by creating a 3D fingerprint of the patient’s other fully developed ear and then collecting cartilage cells from his ear. These are then cultured to obtain a sufficient amount and then mixed with a collagen hydrogel. It is this mixture that is used to print the implant. L’essai clinique must include a total of 11 patients, in California and Texas.

Dr. Bonilla hoped that this implant could one day replace the existing treatments, which involve creating a prosthesis from a cartilage of a rib, or a substance called porous polyethylene. The first solution is a difficult procedure, and the implant using porous polyethylene is less flexible than the one explicitly tested today. The microtie affects about 1,500 babies in the United States each year, according to the company. If they do not have other health problems, these children can live completely normal. But some may misunderstand the gaze of others on this malformation.
