We performed a prospective observational study of BET efficacy, by comparing subjective data, based on the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), and objective data, obtained by tympanometry, objective Valsalva maneuver and tubomanometry, prior to BET with these outcome tools on postprocedure follow-up.<\/jats:p><jats:p>\n               Results\u2003In total, 30 BETs were performed and analyzed. There were no complications with the procedure. Analysis of BET efficacy was performed in the short-term (average of 7.5 weeks) and in the medium-term (average of 8 months). There was a significant reduction (p\u2009&lt;\u20090.0001) in the total ETDQ-7 score from baseline to both follow-up periods. A normalization of the ETDQ-7 score was observed in 60 and 83.3% of the performed procedures, in the short- and medium-term, respectively. In tubomanometry, we verified a significant improvement (p\u2009&lt;\u20090.0001) at all pressures, with a normalization of tubomanometry values in 53.3% and 43.3% of cases in the short- and medium-term, respectively.
