The fitted ear should, over time, provide the appearance, feel, and flexibility of a normal ear, and 11 patients in California and Texas are expected to be included in the clinical trial.
An American medical team managed Human ear transplant surgery They were made from the cells of a patient treated using a 3D printer, indicating that the technology could help people with rare birth defects.
First-of-its-kind surgery was performed as part of a clinical trial to evaluate the safety and effectiveness of this implant in people with small ears whose outer ear is not properly developed.

It comes a few days after the hit Two full arm replacements To a man in the United Kingdom.
The implant is named Orinovo and was discovered by 3D biotherapeutics while being operated on by Arturo Ponila, the founder of a company specializing in the treatment of this defect in San Antonio, Texas, USA.
“As a physician who has treated thousands of children with small ears in all parts of the country and around the world, I am delighted with this technology and what it means for patients and their families,” says one company statement. .
The surgery is performed by creating a three-dimensional appearance of the patient’s other fully developed ear and then collecting his ear cartilage cells.
These cartilages are grown to obtain adequate size and then mixed with collagen hydrogel. This compound is used to print the implant.
The implant is surrounded by a biodegradable printed shell to support it, and the patient’s body absorbs it over time.
The fitted ear should, over time, provide the look, feel and flexibility of natural ears.
Eleven patients in California and Texas are expected to be included in the clinical trial.
Dr. Ponia believes that one day the implant will replace the current treatment that creates the prosthesis by removing the cartilage from the ribs or by removing a material called porous polyethylene.
The company estimates that about 1,500 children in the United States suffer from small ears each year.

These children can live normally without other health problems, but some of them may be negatively affected by others’ perception of this disability.
Maternal diabetes or a lack of adequate carbohydrates and folic acid are factors that increase the risk of developing post-traumatic stress disorder.
In the future, 3D Bio hopes to create implants for more rigid micro ears.
3D implants can also be used for other conditions affecting the cartilage, including defects or injuries to the nose, breast reconstruction or menstrual damage in the knee.
