Abstract

Objective: To assess the efficacy of the Eustachian Tube Dysfunction Questionnaire (ETDQ-7) for patulous Eustachian tube (PET) patients.

Methods: A prospective survey of medical records identified 36 patients and 47 ears with PET, and 15 patients and 15 ears as control. The ETDQ-7, patulous Eustachian tube handicap inventory-10 (PHI-10) and Likert scale were evaluated. PET patients were divided into two groups based on severity of symptoms using the PHI score.

Results: The Cronbach α value of the PET group was 0.765. The average total score of the ETDQ-7 in the control group was 7.6 ± 1.1 and 22.5 ± 10.0 in the PET group (p < .01). No correlation was found between ETDQ-7 and Likert scale (r = 0.248, p = .09). The average total score of the ETDQ-7 in the mild or moderate PET group was 19.9 ± 9.0 and 25.3 ± 11.1 in the severe PET group and this was not statistically different (p = .08).

Conclusion: The highest ETDQ-7 score was also observed in PET patients and in ET dysfunction patients. These findings necessitate careful discrimination between ET dysfunction and PET in balloon dilation Eustachian tuboplasty (BET) based on ETDQ-7.

Keywords: ETDQ-7; Eustachian tube dysfunction; Patulous Eustachian tube; middle ear.
