The Eustachian tube (ET), an anatomic connection between the middle ear (space under the ear drum) and the nasopharynx (back of the nose) helps to ventilate the middle ear space, equalizes pressure between the atmosphere at the middle ear, drains fluid from the middle ear, and helps maintain healthy gas exchange in the middle ear space. Eustachian tube dysfunction (ETD) results in a vacuum under the eardrum, an unhealthy condition that causes several ear pathologies including\u00a0otitis media<\/a>, middle ear atelectasis (eardrum retraction), and\u00a0cholesteatoma<\/a>. The ET is closed most of the time but should open when a person yawns or swallows.<\/p>\n\n\n\n

ETD is normal in children, whose Eustachian tubes are immature and relatively horizontal in orientation compared to adults. This makes them particularly prone to ear infections, which most children outgrow sometime between the ages of 5-7 years. Daycare, exposure to tobacco smoke, family history of ear disease, pacifier use, and formula feeding rather than breastfeeding have been associated with increased ETD and\u00a0otitis media<\/a>. A history of seasonal or perennial allergies can also cause or worsen ETD.<\/p>\n\n\n\n

Most ear disease related to ETD is managed symptomatically or with intermittent use of oral antibiotics. Nasal decongestants, nasal steroid sprays, and oral antihistamines are sometimes trialed. Recurrent ear infections (> 3-4 episodes in 6 months), persistent middle ear effusions with hearing impairment, middle ear atelectasis (eardrum retraction), ossicular dysfunction (impaired vibration of hearing bones), and\u00a0cholesteatoma<\/a>\u00a0are often managed with surgery.<\/p>\n\n\n\n
