Poe D, et al. - The intent here was to investigate the balloon dilation of the Eustachian tube with Eustachian tube balloon catheter in conjunction with medical management as a treatment for Eustachian tube dilatory dysfunction. The balloon dilation of the Eustachian tube with balloon catheter + medical management appeared to be superior to the medical management alone, for the treatment of Eustachian tube dilatory dysfunction in adults.
