Eustachian tube dysfunction and Meniere's disease: a report of 341 cases.

Tympanometric results were reviewed for 341 cases of Meniere's disease and 200 cases of sensorineural hearing loss of unknown causes. The results indicate that the incidence of Eustachian tube dysfunction in patients with Meniere's disease is nearly the same as in a control group of patients with sensorineural hearing loss of unknown causes: The percentage of patients with Meniere's disease having Eustachian tube dysfunction was similar to the percentage of normal-hearing listeners with Eustachian tube dysfunction reported by Jerger.
