Balloon Catheter Dilatation of Eustachian Tube: A Preliminary Study

Objective: Eustachian tube dysfunction is a common problem and transnasal endoscopic balloon dilation of the Eustachian tube (ET) is a new surgical technique. The goal of this study is to review the evolution of this novel technique and study the preliminary outcomes. Subjects and Methods: Balloon catheter dilation of the 100 Eustachian tubes in 70 adults was performed at a tertiary medical center from January 2009 to January 2011. A 5-mm sinus balloon catheter was endoscopically placed transnasally into the proximal ET to dilate the cartilaginous ET. Cases were reviewed with respect to indications, outcomes, and complications. Results: Of the 100 ETs, ear fullness and pressure were improved in 71% of patients studied for 26.3 weeks (+/- 3.6). Of 8 patients followed for a minimum of 34 months, 87% reported persistent improvement. One complication is reported. Conclusion: Endoscopic transnasal ET balloon dilation is a novel approach to treating ET dysfunction. Benefits can be durable up to 3 years. This technique holds much promise and merits further investigation.
