The researchers showed how bone erosion caused by cholesteatoma occurs. This study showed that a subset of cells called osteoclastogenic fibroblasts expresses a protein, activin A, which causes the ...

Chronic inflammation of the middle ear can cause several problems and complications that can affect a person’s hearing and balance. One such problem is the formation of a cholesteatoma, which is an ...

Ear care, or otology, specifically treats the structure and function of the ear. Ear conditions include hearing and balance disorders, damage or disease of the ear, tumors, and others (see below). Our ...

Millions of years ago marine animals had hearing organs that allowed them to detect sounds in the water. When land dwelling animals evolved they now had to detect environmental sounds that traveled ...

The inner ear may not seem like a particularly bony place, but human ears in fact have three small bones (also known as ossicles): the malleus, the incus and the stapes. While most people would assume ...

A single bone in the inner ear marks the difference between the two major groups of bats. The anatomical difference arose very early in the history of these animals. It may have led the two groups to ...

When saltwater fish long ago evolved to live in fresh water, many of them also evolved a more sophisticated hearing system, including middle ear bones similar to those in humans. Subscribe to our ...

Long ago, some saltwater fish adapted to freshwater — and in doing so, developed an extraordinary sense of hearing rivaling ...

Exceptionally preserved skulls of a mammal that lived alongside the dinosaurs may be offering scientists a glimpse into the evolution of the middle ear. The separation of the three tiny middle ear ...
