Abstract

Objectives: To review the diagnosis of patulous Eustachian tube (PET) based on the diagnostic criteria for the PET proposed by Japan Otological Society (JOS). Methods: We reviewed typical aural symptoms of PET, Eustachian tube (ET) obstruction procedure to confirm diagnosis of PET, objective findings of a patent ET obtainable from observation of the movement of the tympanic membrane, and by ET function tests (tubo-tympano-aerodynamic graphy, sonotubometry). In addition, usefulness of other tests such as patulous Eustachian tube handicap inventory-10 (PHI-10), sonotubometry with postural change (Ohta method), and sitting computed tomography (CT) to diagnose PET is described. Results and Conclusions: We have described the diagnosis of PET based on the diagnostic criteria for PET proposed by JOS; PHI-10, Ohta method, and sitting CT are also useful for the diagnosis of PET. Further investigation is needed for an accurate diagnosis and precise evaluation of the pathophysiology of this challenging disease.
