Patulous Eustachian Tube Dysfunction

Eustachian tube dysfunction represents a continuum ranging from obstructive Eustachian tube dysfunction to patulous Eustachian tube dysfunction (pETD), and there is considerable overlap of symptoms that present challenges in the differential diagnosis. Careful history, physical, endoscopic examination, and audiological testing are all important in distinguishing between these conditions and other causes of aural fullness. There are many different treatment modalities, but none are optimal. The most common methods have a good safety record, and they are repeatable. There is a need for more randomized, controlled trials of treatments for pETD.
