Trapped Fluid in the Ear - Eardoc

A middle ear infection is usually caused by blockage of the Eustachian tubes – narrow passages that connect each middle ear to the upper throat (just behind the nose). A simple cold or an upper respiratory tract infection can lead to swelling of these tubes (enough to become blocked), and may result in trapped fluid inside the middle ear, a fertile media for bacterial growth.A middle ear infection is usually caused by blockage of the Eustachian tubes – narrow passages that connect each middle ear to the upper throat (just behind the nose).
