Research on diagnosis and treatment of intractable Eustachian tube disease

Abstract

Intractable Eustachian tube (ET) disease, especially patulous ET, is a condition in which the ET is open for a prolonged or constant period, resulting in unpleasant aural symptoms such as voice and breathing autophony and aural fullness. We have worked on the diagnosis and treatment of this disease using various approaches. In particular, we have conducted a physician-initiated clinical trial of the Kobayashi plug surgery, which will be covered by national health insurance in 2020. We will continue our efforts to further elucidate the pathogenesis of the disease and improve treatment outcomes.
