Abstract

Abstract Objectives: There is no study in the literature that patients with clinically-proven PET were evaluated by Valsalva CT. We aimed to evaluate the merit of Valsalva computed tomography (CT) in patients who had clinically-proven patulous Eustachian tube (PET). Design: Case-series Setting and participants: We recruited patients with clinically-proven PET. Participants: Main outcome measures: All participants underwent temporal bone CTs while they were performing the Valsalva maneuver in the supine position. Standard axial plane CT images, along with multiplanar reconstruction and 3D Air volume rendering, were used to visualize the ET in its entirety. Results: Three patients (2 females, one male) with a total of 6 ears were included in the study. All patients had suggestive symptoms of PET, including aural fullness, aerophony, and autophony and underwent clinical examination and audiologic tests. In all ears, the whole Eustachian tube could be visualized with Valsalva CT. Conclusion: For the first time, we demonstrated the merit of Valsalva CT in visualization of the Eustachian tube in its entirety in patients with clinically diagnosed PET.
