Objective: To determine whether balloon dilation of Eustachian tube (BDET) improves postoperative audiology and quality of life scores in children with chronic Eustachian tube dysfunction.
Study design: Retrospective study.
Setting: Tertiary care pediatric center.
Methods: Eligible participants were patients 8 years or older, with a history of 2 prior tubes placement. Group 1-patients completed pre-and post-Eustachian Tube Dysfunction Quality of Life Survey (ETDQ-7) survey scores, Group 2-patients had available pre- and postdilation tympanogram data (TD), and Group 3-patients had both ETDQ-7 survey and TD. The average time for the first and subsequent follow-ups was 3.8 and 12.9 months, respectively.
Results: A total of 43 patients (85 ears) underwent BDET. The mean age was 13.3 years (8-18 years). Twenty-four patients were male (55.8%) and over 80% were Caucasian. The average mean ETDQ-7 score before and after dilation was 3.9 and 2.5, respectively. Ninety-three percent experienced improvement of their postoperative ETDQ-7 scores and 53% had normal postdilation ETDQ-7 score (P < .0001). Thirty-seven ears in Group 2 (60.7%) had improvement in postdilation TD. A greater proportion of ears showed improvement of 62.3% with a 95% confidence interval (CI) [50.1%-74.5%] compared to 37.7% without improvement, 95% CI [25.5%-49.87%]. Ears with type A or B TD were more likely to show improvement than ears with type C, perforated, or with tubes (P < .0001). Eighteen out of 30 ears in Group 3 (60%) experienced an improvement in both ETDQ-7 and tympanogram.
Conclusion: BDET is a safe, efficacious alternative to tubes in selected pediatric patients.
