RecruitingPhase 2Drug trialEffect of Novel Exhalational Delivery System With Fluticasone (EDS-FLU) on Eustachian Tube Dysfunction (ETD)Intranasal nasal steroid sprays are the mainstay of treatment for chronic Eustachian tube dysfunction despite having little supportive evidence in the literature. A novel, commercially available nasal spray delivery system is available now for fluticasone that improves its delivery to the nasopharynx. The hypothesis of this study is that fluticasone using the novel spray system is effective for Eustachian tube dysfunction (ETD).
