title: Radiology of the Eustachian fossa.
abstract: The Eustachian fossa, when visualised in contrast radiography and cinefluorography, shows a wide variety of shapes and sizes. Moreover, the fossa also exhibits varying degrees of changes during swallowing. Brief accounts of the technique of contrast radiography and the appearance of the normal nasopharyngograms are given to facilitate the understanding of the radiological features of the fossa.
