What is eustachian tube dysfunction?
The eustachian tube is a cartilaginous and bony tube providing a connection between the nasopharynx and the middle ear. At rest, the eustachian tube is closed, but it opens on swallowing, yawning, sneezing, and the Valsalva manoeuvre due to contraction of palatine muscles. When the eustachian tube opens it facilitates equalisation of pressures between the external environment and the middle ear by allowing a bolus of air to pass through.
Dysfunction of the eustachian tube results in development of negative pressures within the middle ear, leading to transudation of fluid and a pro-inflammatory response. Consequentially, eustachian tube dysfunction is an important component of pathology of the middle ear, particularly acute otitis media and otitis media with effusion.
