OBJECTIVE: The aim of this study was to evaluate the relationship between chronic nasal obstruction caused by inferior turbinate enlargement and Eustachian tube dysfunction-related symptoms using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7) as an assessment method. METHODS: A total of 80 adults were enrolled. Group 1 comprised consecutive patients with enlarged inferior turbinates and group 2 comprised healthy controls. The ETDQ-7 scores and tympanometry results of both groups were analyzed and compared. RESULTS: The median total scores of the ETDQ-7 in groups 1 and 2 were 1.9 (interquartile range, 1.4-2.8) and 1.1 (interquartile range, 1.0-1.7), respectively ( P < .001). There was no significant difference in the abnormal tympanometry results between the groups. There was no significant difference in the ETDQ-7 total score between the patients with allergic sensitization and other patients in group 1. CONCLUSIONS: Patients with inferior turbinate enlargement have more symptoms related to Eustachian tube dysfunction than healthy controls. Most patients with Eustachian tube dysfunction had normal tympanometry and normal otoscopy, which indicates a baro-challenge-induced Eustachian tube dysfunction. Whether the patient has allergic sensitization or not does not seem to cause a difference in symptoms related to Eustachian tube dysfunction.
