Prospective Evaluation of the Efficacy of Isolated Balloon Eustachian Tuboplasty: Short- and Medium-term Follow-up Results Based on Tubomanometry, ETDQ-7, Tympanometry, and Valsalva Maneuver

Balloon eustachian tuboplasty (BET) allows the treatment of the main etiology of eustachian tube disfunction (ETD). To evaluate the efficacy of isolated BET, through objective and subjective results, in the short and medium term, in patients with chronic obstructive ETD. Adult patients diagnosed with chronic obstructive ETD who underwent BET between January 2018 and December 2020 were enrolled in the study. 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. In 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 (
