摘要
Objective To examine the effectiveness of eustachian tube balloon dilation for the treatment of eustachian tube dysfunction. Data Sources PubMed, Scopus, and Google Scholar. Review Methods A systematic review of eustachian tube balloon dilation for the treatment of eustachian tube dysfunction was conducted following Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) guidelines to identify randomized control trials and prospective and retrospective studies published prior to January 31, 2019. Meta‐analysis of proportions evaluated 7‐item Eustachian Tube Dysfunction Questionnaire (ETDQ7) scores, tympanometry, otoscopy findings, and the ability to perform a Valsalva maneuver. Results The systematic review identified 35 studies. Twelve studies met inclusion for meta‐analysis (448 patients). Mean ETDQ7 scores decreased by 2.13 from baseline to 6 weeks (95% CI, –3.02 to −1.24; P <. 001). From baseline to 6 weeks, 53.0% of patients had improvement in tympanograms ( P <. 001). At the long‐term point (3‐12 months), 50.5% of patients had improved tympanograms from baseline ( P <. 001). There was no significant difference in the proportion of improved tympanograms at 6 weeks compared to long term ( P =. 535). Normal otoscopy exams at baseline increased by 30.0% at 6 weeks ( P <. 001) and 55.4% in the long term ( P <. 001). There was a 67.8% increase in proportion of patients able to perform a Valsalva maneuver in the long term compared to baseline ( P <. 001). Conclusion Eustachian tube balloon dilation appears to be associated with improvement in subjective and objective treatment outcome metrics. The improvement appears stable at 3 to 12 months after dilation. Patients with eustachian tube dysfunction are likely to benefit from balloon dilation, particularly those with medication‐refractory disease.
