Eustachian tube dysfunction in patients with house dust mite-allergic rhinitis

Abstract

AR patients, especially those with severe nasal obstruction, could have ETD. The local conditions of the pharyngeal orifices of the eustachian tubes are closely related to the symptoms of ETD. After treatment with nasal glucocorticoids and oral antihistamines, eustachian tube function can significantly improve as nasal symptoms subside.<i>Trial registration</i> Chinese Clinical Trial Registery (ChiCTR2000029071) Registered 12 January 2020-Retrospectively registered, http://www.chictr.org.cn/edit.aspx?pid=48328&htm=4.
