Outcomes and Complications of Pediatric Eustachian Tube Dilation Surgery

Abstract

AbstractObjectiveTo determine whether balloon dilation of Eustachian tube (BDET) improves postoperative audiology and quality of life scores in children with chronic Eustachian tube dysfunction.Study DesignRetrospective study.SettingTertiary care pediatric center.MethodsEligible 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.ResultsA 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.ConclusionBDET is a safe, efficacious alternative to tubes in selected pediatric patients.
