[Clinical application of seven-item Eustachian Tube Dysfunction Questionnaire].

Objective: To investigate the clinical value of the seven-item Eustachian Tube Dysfunction Questionnaire(ETDQ-7) in evaluating Eustachian tube dysfunction before and after treatment. Method: A retrospective analysis of 50 patients with Eustachian tube dysfunction diagnosed. All the patients were given chymotrypsin 4 000 IU and dexamethasone injection 5 mg by blowing through the Eustachian tube under nasal endoscopic guidance once daily for 3-6 consecutive days. At the same time, azelastine hydrochloride nasal spray and budesonide nasal spray were applied, 2 sprays each time, 2 times a day; oral Olongma drops, 3 ml each time, 3 times a day. ETDQ-7 was completed before and after treatment, and the results of ear endoscopy, pure tone audiometry, acoustic impedance test, and Eustachian tube function test were analyzed comprehensively. Result: The ETDQ-7 score(15.6±7.1) after treatment was significantly higher than that before treatment(23.1±6.5) points ( P <0.05), and the difference was statistically significant. After treatment, all patients felt that aural fullness, tinnitus or discomfort, hearing loss and other symptoms were relieved. The tympanic membrane was observed to be better than before treatment. The tympanic effusion and tympanic membrane invagination were improved, which was in line with the change of ETDQ-7 score. Conclusion: ETDQ-7 has a good clinical value in the evaluation of Eustachian tube dysfunction before and after treatment. It is a reproducible and effective method for evaluating Eustachian tube dysfunction(ETD).
