Chronic obstructive Eustachian tube dysfunction: CT assessment with Valsalva maneuver and ETS-7 score
Chronic obstructive Eustachian tube dysfunction (ETD) is a common disorder of the middle ear.
In recent years, two main diagnostic tools have become available: Eustachian tube score (ETS-7) and computed tomography (CT) combined with Valsalva maneuver. The aim of this
