A method of making moulds of the nasopharynx is described. Thirteen moulds are illustrated. A mould constitutes one form of morphologic study of the nasopharynx. A mould shows clearly the form and shape of nasopharynx. A positive cast may be made. Moulds are useful for class demonstrations and for teaching purposes.
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.
