Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate, and the vibrations are conducted to the nearby cochlea. The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain.The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear. They send information on balance and head position to the brain. Otitis media (middle ear inflammation): Inflammation or infection of the middle ear (behind the eardrum). 2  Usually, this is caused by an infection. 3  Swimmerâs ear (Otitis externa): Inflammation or infection of the outer ear (pinna and ear canal).
