OBJECTIVES/HYPOTHESIS: To assess balloon dilation of the Eustachian tube with Eustachian tube balloon catheter in conjunction with medical management as treatment for Eustachian tube dilatory dysfunction.

STUDY DESIGN: In this prospective, multicenter, randomized, controlled trial, we assigned, in a 2:1 ratio, patients age 22 years and older with Eustachian tube dilatory dysfunction refractory to medical therapy to undergo balloon dilation of the Eustachian tube with balloon catheter in conjunction with medical management or medical management alone.

METHODS: The primary endpoint was normalization of tympanogram at 6 weeks. Additional endpoints were normalization of Eustachian Tube Dysfunction Questionaire-7 symptom scores, positive Valsalva maneuver, mucosal inflammation, and safety.

RESULTS: Primary efficacy results demonstrated superiority of balloon dilation of the Eustachian tube with balloon catheter + medical management compared to medical management alone. Tympanogram normalization at 6-week follow-up was observed in 51.8% (72/139) of investigational patients versus 13.9% (10/72) of controls (P < .0001). Tympanogram normalization in the treatment group was 62.2% after 24 weeks. Normalization of Eustachian Tube Dysfunction Questionaire-7 Symptom scores at 6-week follow-up was observed in 56.2% (77/137) of investigational patients versus 8.5% (6/71) controls (P < .001). The investigational group also demonstrated substantial improvement in both mucosal inflammation and Valsalva maneuver at 6-week follow-up compared to controls. No device- or procedure-related serious adverse events were reported for those who underwent balloon dilation of the Eustachian tube.

CONCLUSIONS: This study demonstrated superiority of balloon dilation of the Eustachian tube with balloon catheter + medical management compared to medical management alone to treat Eustachian tube dilatory dysfunction in adults.

LEVEL OF EVIDENCE: 1b Laryngoscope, 2017.
