Sound from the meatus travels through the air and bounces onto the ear drum or tympanic membrane, causing it to vibrate. Behind the ear drum are the ossicles, commonly known as the hammer anvil and stirrup that contract and relax in response to the vibration of the eardrum.
Glue ear is a common middle-ear condition, particularly in children, that can cause a conductive hearing loss. If glue ear is persistent it might require ENT intervention and the placement of grommets. Although not as common, it can also occur in adults. If grommets are unsuitable the resulting hearing loss can be managed with hearing aids.
