Say goodbye to the cauliflower ears! Chinese scientists have created an injection that corrects misshapen ears in mice and could work in humans
- Deformed ears are a hallmark of contact sports, including boxing and rugby
- Chinese scientists have found a way to sculpt cool 3D tissue bioprinting
- It was tested in mice and was able to create a new ear in the form of supporting tissue and to correct the defects
People living with defects of the ear, including the stars of the sport pest of cauliflower ears, soon you may be able to repair the decades of damage with a single injection.
Deformed ears are the hallmark of many contact sports, that plague the ex-boxers, rugby players and wrestlers because of the repetitive blunt force trauma.
The experiments on mice carried out by Chinese scientists found a way of sculpting a new tissue using a 3D bioprinting technique.
The study found that the method was very effective and able to create new of the ear in the form of supporting tissue and to correct the defects.
Deformed ears are the hallmark of the many sports of contact, which affects many ex-boxers, rugby players and wrestlers, owing to the repetition of certain bunt force trauma.

The non-invasive technique successfully formed a perfect ear in mice that had been genetically programmed to develop deformed ones.
They corrected their bodies, so it looked perfect, and it is thought the procedure could be applied to human beings.
It could also lead to the replacement of other parts of the body, without a risky operation.
Co-author Professor Maling Gou, said: ‘The technology could be adapted for clinical use in humans.
“This could potentially allow many different types of surgery minimally invasive or non-invasive reconstructive surgery.’
Cauliflower ears are caused by repeated blunt force trauma. It is a permanent condition, and at present can only be fixed through surgery. UFC star Randy Couture (in the photo) is a victim. Chinese scientists are working in a non-invasive method for the treatment of malformed ears
Cauliflower ears are caused by blunt force trauma
Deformed ears are the hallmark of the many sports of contact, which affects many ex-boxers, rugby players and wrestlers, owing to the repetition of certain bunt force trauma.
It is a permanent condition occurs when the cartilage of the ear is injured by trauma or inflammation.
Blood supply of the skin is broken, often forming a large pocket of blood, called a hematoma.
As the damage to the ear healthy can be folded on itself and appear pale, giving it a cauliflower-like appearance.
Wrestlers, boxers, rugby players and martial artists are susceptible to this type of injury.
A microchip called DMB (digital micromirror device) with a measurement pattern is inserted under the skin.
This triggers the ‘bioink’, which is filled with a cocktail of chemicals and cells of cartilage, which simultaneously is administered under the skin in the back of the ear.
The ink then begins the correction of the structure of the ear by the creation of new structures, layer-by-layer.
A month later, the cartilage had maintained its shape and it was also colonized by the blood vessels, and muscles that began to grow and renew itself normally.
The international team of the method creates layers of tissue similar to how the spare parts are built by 3D printers in the industry.
Professor Gou, of the University of Sichuan, China, said: “After 20 seconds, the ear began to take shape”.
The ‘bioink’, described in the Science Advances, it is indicated the use of beams of near-infrared light.
“It is possible to provide a surgery free option for humans with this condition are often subjected to implant surgery in the risk of injury,’ Professor Gou, he adds.
“More broadly, this technique of 3D printing may open a new pathway for non-invasive medicine to treat other conditions and reconstructive needs.”
