Eustachian Tube Function in Patients With Eosinophilic Otitis Media Associated With Bronchial Asthma Evaluated by Sonotubometry

Abstract

The presence of a patulous eustachian tube may be a major cause of EOM in patients with bronchial asthma. In patients with asthma who have a helper T-cell 2-dominant predisposition, a patulous eustachian tube easily allows the entry of antigenic materials into the middle ear, causing eosinophil-dominant inflammation.
