Ears

Many times those that suffer hearing loss do so because of an irregularity of how their ear is formed. By simply changing the shape of their ear or by adding more to an underdeveloped ear, hearing can be improved dramatically, changing a person’s life and helping them to function more safely in the world.

Scientists have discovered a way to build ears with the use of existing cells. When the new ear is being formed, it is inserted with cartilage cells and collagen from actual humans. This advance allows the transplant a higher success rate since the ear is formed from actual cells, rather than other materials.
