INTRODUCTION: Eustachian tube dysfunction (ETD) may result in hearing loss, chronic otitis and cholesteatoma. With advances in treatment options, the identification of patients with obstructive ETD is becoming increasingly important. The objective of this study was to validate a Danish translation of the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7).

METHODS: All participants underwent tympanometry, otomicroscopy and completed the ETDQ-7. We included 34 ears from patients with obstructive ETD who had abnormal tympanometry curves but no history of cholesteatoma or adhesive otitis. As a control group, 48 otherwise healthy ears with a normal tympanometry curve were included from patients with known sensorineural hearing loss or normal hearing.

RESULTS: A Cronbach's alpha of 0.77 indicated a good internal consistency reliability of the questionnaire. The mean ETDQ-7 score in the obstructive ETD group was 31 versus 13.5 in the control group (p = 0.00). A receiver operating characteristics analysis produced an area under the curve of 94%, showing excellent discriminatory abilities between the groups.

CONCLUSIONS: The ETDQ-7 has previously been validated in English, German, Dutch and Portuguese, demonstrating good clinical relevance. The Danish translation of the ETDQ-7 has produced similar results and may be valuable in diagnosing obstructive ETD and in monitoring the effect of balloon dilation of the Eustachian tube.

FUNDING: none. The study was approved by the Danish Data Protection Agency (VD-2018-33, I-Suite 6229).
