Is this trial a fit for you?

Likely a good fit

Probably not a fit

Patients with a history of otologic surgery, tympanic membrane perforation, or other significant ear conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of a novel exhalational delivery system for fluticasone in treating chronic Eustachian tube dysfunction (ETD). The study involves administering fluticasone via a specialized nasal spray to improve medication delivery to the nasopharynx. Participants will be monitored for symptom improvement and changes in tympanometry results. The trial aims to provide better treatment options for patients suffering from ETD, which currently lacks FDA-approved medications.

Why it matters

Potential benefit: If successful, this study could offer a more effective treatment option for patients with chronic Eustachian tube dysfunction.

How similar studies have gone: While there is limited evidence supporting the use of nasal sprays for ETD, this novel approach has not been extensively tested in prior studies.
