The Accuracy of Sonotubometry to Assess the Eustachian Tube

Status Recruiting

Clinical Trial Summary

The Eustachian tube (ET) connects the middle ear with the throat and is important for maintaining a healthy middle ear. Sonotubometry is a new method to measure how well the ET works by using sound. A speaker is placed at the nostril and a microphone records sound in the external ear canal. The ET is closed at rest and opens with swallowing. This is measured as an increase in sound measured in the external ear by sonotubometry. Previous research has not proven that sonotubometry is reliable enough to be used in clinics to assess ET dysfunction (a disease where the ET does not open properly). In a recent study with healthy volunteers, it was possible to identify many of the existing issues of sonotubometry and improve the reliability of this method. This was primarily achieved by testing different sound types and sound volumes. This study aims to assess the reliability and usability of the new testing protocol in study participants with ET dysfunction. The results of this study will then be compared with the results from the previous study with healthy volunteers to work out how well sonotubometry works. Ultimately, this research aims to improve the ability to diagnose ET dysfunction.
