| In the middle ear are three tiny lever-like bones that carry sound vibrations from the eardrum to the inner ear. |
| Lying beyond the eardrum is the middle ear, a tiny air-filled cavity in the temporal bone. |
| Then I realized that I couldn't hear anything at all, nothing but a constant thudding like a heartbeat in my eardrum. |
| To examine the ear, doctors use an otoscope, a small instrument similar to a flashlight, through which they can see the eardrum. |
| Otitis externa, the clinical term for swimmer's ear, is an inflammation of the canal joining the eardrum to the external ear. |
| In rare cases the eardrum will become perforated, and pus will then be seen running out of the ear. |
