Balloon Dilation of the Eustachian Tube (BDET)

Eustachian tube balloon dilation (BDET) can be considered after specialist evaluation when there is chronic Eustachian tube dysfunction, pressure intolerance, or recurrent secretory otitis media, and the effects of medication and self-ventilation training are limited. The decision is based on a comprehensive assessment of endoscopic findings, tympanometry and audiometry results, nasopharyngeal anatomy and inflammation status, and overall health. It is also necessary to assess whether there are coexisting nasal/adenoid problems that need to be addressed simultaneously.
