Diagnostic criteria for Patulous Eustachian Tube: A proposal by the Japan Otological Society
Section snippets
Background
The Patulous Eustachian Tube (PET) has long been considered a unique but relatively rare disorder [1], [2], [3], [4], [5]. In recent years, however, there has been a remarkable increase in the number of clinical reports and studies on PET [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49],
Concept of the JOS diagnostic criteria for Patulous Eustachian Tube 2016
The JOS diagnostic criteria for Patulous Eustachian Tube 2016 was formulated to avoid any contamination of “Definite PET” with uncertain cases, so that “Definite PET” accurately reflects PET cases. Moreover, it was also intended to minimize the number of cases that could be accidentally excluded even in the presence of some suspected findings (“Possible PET”).
The criteria can be used by all otolaryngologists even without using the Eustachian tube function test apparatus. However, the use of
JOS diagnostic criteria for Patulous Eustachian Tube 2016
The JOS diagnostic criteria for Patulous Eustachian Tube 2016 (Fig. 1), the notes for the criteria (Table 1, Fig. 2, Fig. 3) and the algorithm for diagnosis of PET using the criteria (Fig. 4) are shown.
Conclusion
The JOS diagnostic criteria for Patulous Eustachian Tube will further promote international scientific communication on PET.

Hearing Dysfunction After Treatment With Teprotumumab for Thyroid Eye Disease
2022, American Journal of OphthalmologyCitation Excerpt :Mechanisms for PET development are likely different. PET is a middle ear condition with symptoms of plugged ears, fullness, and autophony due to ET patency.53-56 Potential etiologies include patency within the ET cartilaginous portion57 or loss of fat or glandular tissue around the ET opening.58,59
Objective assessment of autophony during phonation in the diagnosis of patulous Eustachian tube patients
2021, Auris Nasus LarynxCitation Excerpt :To date, there have been no diagnostic criteria for PET, and each institution typically uses its own means of diagnosing PET. The Japan Otological Society (JOS) has recently advocated for the standardization of diagnostic criteria for PET [2]. We have recently made revisions to this system for better clinical application by adding the calculation of the ratio of voice sound and noise sound transmitted in the EAC (EAC/Voice).
Pulsatile tinnitus caused by pneumocephalus after Janneta surgery
2021, Auris Nasus LarynxCitation Excerpt :Audiogram (Fig. 1: right) showed normal hearing of 3.3 dB (averages of 500, 1000, and 2000 Hz) in the right ear. Tympanogram was of the normal A-type, and Eustachian tube function tests using tubo-tympano-aerodynamic graphy (TTAG) [2] and sonotubometry [3] did not show evidence of patent ET according to the Japan Otological Society Criteria of Patulous ET (Fig. 1: left) [4]. Cone-beam computed tomography (CT) taken in the sitting position (sitting CT) showed no evidence of patent ET [5,6].
