Eustachian Tube Endoscopy in Patients With Chronic Ear Disease

Objectives/Hypothesis A paucity of research exists on trans–eustachian tube endoscopy to evaluate the status of the eustachian tube. Fuller examination of the role of the eustachian tube in chronic ear disease is needed, particularly because the eustachian tube has been implicated in the chronicity and pathogenesis of chronic ear disease. Therefore the purpose of this study was to evaluate the eustachian tube, based on observations from trans–eustachian tube endoscopy.
