Efficacy of Balloon Dilation of the Eustachian Tube in Eustachian Tube Dilatory Dysfunction

Patients in the intervention group would undergo balloon dilation of the eustachian tube under local anesthetic in clinic. The Stryker XprESS LoProfile ENT dilation system or the Stryker Audion ET dilation system will be used.

Patients in the sham group will undergo the motions of an in-office dilation of the eustachian tube, without actually dilating the eustachian tube.
