[Radiological examination of the eustachian tube. Radiomanometry technique (author's transl)].

Radiomanometry is a modified technique for visualisation of the auditory tube. The contrast material is injected through a perforated tympanic membrane with control of injection pressure. Three positions are recommended: sub-mento-vertical, Worms, and modified Stenvers. The normal aspect of the tube is described with variations. Some pathological obstructtions are demonstrated. However, it must be underlined that many tubes with abnormal manometric test were not abnormal at the radiological evaluation: fonctionnal aspect is more important than anatomical one in the inflammatory pathology of the tube.
