Fossils of an ancient egg-laying mammal indicate that the configuration of the bones in all living mammals’ ears arose at least twice along independent evolutionary pathways, paleontologists say. The ...

Scientists are reporting the first direct evidence that a subtle change in the physical properties of a tissue can affect its function. Scientists are reporting the first direct evidence that a subtle ...

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 ...

A bone conduction hearing aid (BCHA) helps with conductive hearing loss, which is caused by damage to the outer and middle parts of your ear. Keep reading to learn more about BCHA, including how it ...

Sound waves pass from the ear canal in the outer ear to the middle ear and create a vibration of the eardrum. Due to the vibrations of the tiny bones in the middle ear, we are able to hear sound. When ...

An imaging technique able to visualize the sound-induced vibrations traveling through the middle ear could offer new information about how the ear processes sound waves, and assist clinicians treating ...

A mastoidectomy is a type of surgery that removes an infection from the bone behind the ear, called the mastoid bone. The mastoid bone looks like a honeycomb, and the spaces are filled with air. Due ...

Doctors may diagnose hearing loss using a range of techniques, such as audiometry tests, brainstem auditory evoked response tests, and otoacoustic emissions tests. Hearing loss can affect one or both ...
