A Systematic Review of Eustachian Tube Procedures for Baro‐challenge Eustachian Tube Dysfunction

Objective To examine the effectiveness of Eustachian tube procedures for the treatment of baro‐challenge Eustachian tube dysfunction. Methods Following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, databases, including PubMed (National Library of Medicine, National Institutes of Health), Scopus (Elsevier), and CINAHL (EBSCO), were searched for articles examining the effectiveness of Eustachian tube procedures for baro‐challenge Eustachian tube dysfunction. Outcome measures included symptom resolution, ability to return to work, equalization problems (EP) scores, Eustachian Tube Dysfunction Questionnaire (ETDQ‐7) scores, and pressure chamber testing parameters. Pooled meta‐analysis was performed for dichotomous measures and ETDQ‐7 scores. Results Eleven articles with 81 patients were included. Seventy‐two patients from 10 articles underwent balloon Eustachian tube dilation; nine patients in 1 study underwent laser Eustachian tuboplasty (LET). All 81 patients were preoperatively symptomatic with barometric pressure change, and 26/30 (86.7%) were unable to work due to symptoms. On meta‐analysis, after balloon dilation Eustachian tuboplasty (BDET), 82.5% (n = 30 [95% confidence interval: 42%–100%]) had improvement in ability to valsalva, 79.1% (n = 16 [57.9%–94.1%]) in ability to return to work, and 84.3% (n = 69 [69.8%–94.7%]) in any symptom. Of 25 patients with individual ETDQ‐7 scores, 79.1% [51.4, 96.9] had improvements after BDET. For four case series with 36 patients, ETDQ‐7 scores decreased by 1.2 [0.7, 1.7] (p 2.0, there was a mean decrease of 2.1 [1.3, 2.8] (p
