Objective:
Evaluation of the severity of Eustachian tube dysfunction using the Spanish validation of the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) and tubomanometry (TMM).
Materials And Methods:
Spanish validation of the ETDQ-7.
Patients:
Prospective study with 125 patients, 75 of whom reported symptoms compatible with Eustachian tube dysfunction.
Outcome Measures:
The Spanish version of the ETDQ-7 was administered after translation and back-translation. Internal consistency and reliability were established. Usefulness evaluation of TMM plus ETDQ-7 in the study of Eustachian tube dysfunction.
Results:
The Spanish adaptation of the ETDQ-7 showed high reliability and internal consistency. TMM and ETDQ-7 together showed increased sensitivity and specificity in the diagnosis of Eustachian tube dysfunction.
Conclusions:
The Spanish adaptation of the ETDQ-7 is valid, reliable and can be used in a clinical setting to quantify the impact and severity of chronic dysfunction on patients' lives. A new test formed by combining ETDQ-7 and TMM could be a routine test in the diagnosis of Eustachian tube dysfunction.
