Summary
This summary is machine-generated.

The Danish Eustachian Tube Dysfunction Questionnaire (ETDQ-7) accurately identifies obstructive Eustachian tube dysfunction (ETD). This validated tool aids in diagnosing ETD and monitoring treatment effectiveness.

Area of Science:

  • Otolaryngology
  • Audiology
  • Medical Diagnostics

Background:

  • Eustachian tube dysfunction (ETD) can lead to significant hearing impairment and middle ear pathologies like cholesteatoma.
  • Accurate identification of obstructive ETD is crucial for effective patient management and treatment selection.

Purpose of the Study:

  • To validate a Danish translation of the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7).
  • To assess the reliability and discriminatory power of the Danish ETDQ-7 in patients with obstructive ETD.

Main Methods:

  • Participants underwent tympanometry and otomicroscopy.
  • The Danish ETDQ-7 was administered to 34 ears with obstructive ETD and 48 control ears.
  • Statistical analyses included Cronbach's alpha and receiver operating characteristic (ROC) analysis.

Main Results:

  • The Danish ETDQ-7 demonstrated good internal consistency reliability (Cronbach's alpha = 0.77).
  • The obstructive ETD group had significantly higher mean ETDQ-7 scores (31) compared to the control group (13.5; p = 0.00).
  • ROC analysis showed excellent discriminatory ability with an area under the curve of 94%.

Conclusions:

  • The validated Danish ETDQ-7 is a reliable tool for diagnosing obstructive ETD.
  • This questionnaire can assist clinicians in monitoring treatment outcomes, such as after balloon dilation of the Eustachian tube.
