Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older with clinician-confirmed patulous Eustachian tube dysfunction and a positive Cottle maneuver, who can consent and complete surveys.
✕Probably not a fit
Patients with active middle-ear disease, nasal pathology preventing safe use, or intolerance to nasal dilators may not benefit.

What this trial studies
This is a single-arm, prospective pilot study assessing a commercially available internal nasal dilator (Airmax) in adults with confirmed patulous Eustachian tube dysfunction and a positive Cottle maneuver. Symptoms are measured at baseline, 10 minutes after first use, and at a 3–4 week follow-up using the PHI-10 questionnaire. The goal is to estimate effect sizes to guide future controlled trials, with the device used off-the-shelf and no device modification. The study is exempt from IDE requirements under applicable FDA regulations and is conducted at a single Houston Methodist otolaryngology site.
Why it matters
Potential benefit: If successful, patients may experience reduced ear fullness, autophony, and disrupted hearing when using a simple, OTC nasal dilator.
How similar studies have gone: Prior use of nasal dilators for nasal obstruction is common, but this is among the first to study them for patulous Eustachian tube symptoms.
