Medical Management for Eustachian Tube Dysfunction in Adults: A Systematic Review and Meta-Analysis

Neil K Mehta et al. Laryngoscope. 2022 Apr.

Abstract

Objective: Medical treatment for eustachian tube dysfunction (ETD) is varied, with physician preference driving treatment choice and limited guidance for these options. An evaluation of the efficacy of medical management (MM) for ETD is warranted.

Methods: A systematic review of three databases (PubMed, Scopus, and Embase) was performed through December 2020. Adults treated nonsurgically for ETD were included. Exclusion criteria were as follows: patulous ETD, ETD deriving from craniofacial anomalies, or surgical treatment. Data were extracted independently by two reviewers according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A meta-analysis of continuous measures, proportions, and risk ratio was conducted.

Results: Twelve articles were identified by systematic review, with either level 2 or 3 evidence. A meta-analysis of available data was performed on nine studies. A pooled cohort found 50.3% (95% confidence interval [CI], 41.7-59.0) of patients experienced symptomatic improvement with MM. ETDQ-7 scores improved in a clinically nonsignificant manner by -0.88 (95% CI, -1.12 to -0.64) following medical treatment. Further, MM benefited from subacute and chronic symptoms in 30% to 64% and 11% to 50% of cases, respectively. Intranasal corticosteroids (INCS) were not efficacious, improving only 11% to 18% of chronic cases. Therapies such as Politzer devices and Valsalva therapy had minimally beneficial results.

Conclusion: Our review did not find any level 1 evidence for MM of ETD in adults. Available evidence indicates INCS are ineffective for chronic symptoms and the efficacy of nonsurgical options for subacute ETD has yet to be determined. Further randomized controlled trials are needed to discern efficacy of single-agent medical therapies. Laryngoscope, 132:849-856, 2022.
