Tubomanometry and EarPopper Devices for Eustachian Tube Function Testing
NCT03850197 · View on ClinicalTrials.gov ↗
Study Summary
The Eustachian tube (ET) is a biological tube that links the middle ear to the back of the nose and throat. It has several functions, of which the most important is to maintain optimal middle-ear health. Eustachian tube dysfunction (ETD) can result in pain or a popping sensation in the ears when flying in an airplane or going up a tall building in an elevator. Many people with ETD also suffer from ear problems such as repeated middle-ear infections or fluid in the ears. However, there are very few easily-administered tests to measure and assess Eustachian tube function (ETF). Tubomanometry is one of these tests, however it is expensive and used to measure ETF only in research settings. In this study, the investigators propose that using a combination of two readily available devices, the EarPopper and a tympanometer, will work in a manner similar to a Tubomanometer to test ET function.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03850197
The ClinicalTrials.gov registry entry for NCT03850197 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 30 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Cuneyt M. Alper, which has 2 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Eustachian Tube Dysfunction appearing as the primary indexed condition, and to 3 interventions — of which EarPopper is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03850197 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
