Determine the safety and efficacy of balloon dilation of the Eustachian tube (ET) in pediatric patients.Retrospective matched cohort study.Tertiary medical center.Pediatric patients (<18 yr) with persistent (>1.5 yr) chronic Eustachian tube dysfunction (ETD) with previous tympanostomy tube (TT) insertion versus matched controls.Balloon dilation of the cartilaginous ET (BDET) was performed using concomitant myringotomy with/without tube placement and adjunctive procedures if indicated versus controls (TT).Otitis media with effusion (OME)/retraction with need for additional tube, tympanogram, audiogram, otomicroscopy, ET mucosal inflammation/opening score, and Valsalva maneuver.Forty six ETs (26 patients), ages 7 to 17 years (mean 12.5) underwent BDET. Mean follow-up was 2.3 years (standard deviation [SD], 1.1; range, 6 mo-5 yr). Significant improvements were observed for all measures. Tympanic membranes were healthy in 9% preoperatively, 38% at 6 months, 55% at 12 months, and 93% at 36 months postoperatively. Tympanograms improved to type A in 50% at 6 months, 59% at 12 months, and 85% at 36 months. Mean scores of mucosal inflammation declined from 3.2 (±0.6) preoperatively to 2.5 (±0.7) at 6 months and 1.7 (±0.6) at 36 months postoperatively. BDET had lower risk of failure versus TT insertion (adjusted hazard ratio [HR] 0.26; 95% confidence interval [CI]: 0.10, 0.70; p = 0.007). Probability of being failure free at 2 years was 87% (95% CI: 70, 94%) after BDET and 56% (95% CI: 40, 70%) after TT insertions.BDET is a safe and possibly effective procedure in selected pediatric patients with chronic ETD.
