External Auditory Meatus

Summary Information: External Auditory Meatus

External Auditory Meatus: The external auditory meatus is a tube in the outer ear that runs through the temporal bone in the skull. Sound waves travel from outside the body to the middle ear through the external auditory meatus. The external auditory meatus connects the outermost, external structure of the ear, the auricle, to the tympanic membrane.

Sound waves travel through the outer ear, into the middle ear where they cause vibration of the tympanic membrane. These vibrations are then transmitted through the auditory bones and into the cochlea of the inner ear. In the inner ear, sound vibrations are converted into electrical impulses and carried by the 8th cranial nerve to the brain.

Conditions that can afflict the external auditory meatus include swimmer's ear, stenosis, foreign bodies, and trauma.
