Abstract

Objective

Eustachian tube dysfunction is prevalent in both paediatric and adult populations. Current clinical guidelines recommend observation over topical intranasal corticosteroids for Eustachian tube dysfunction management, which remains controversial. This study aimed to systematically review randomised, controlled trials assessing topical intranasal corticosteroid efficacy in Eustachian tube dysfunction, and analyse effect through tympanometric normalisation.

Methods

PubMed, EMBASE, Web of Science and Cochrane Library databases were searched. All randomised, controlled trials assessing intranasal corticosteroids in adult or paediatric Eustachian tube dysfunction patients were included. A meta-analysis of proportions was used to evaluate tympanogram normalisation.

Results

Of 330 results, eight randomised, controlled trials met inclusion criteria and underwent qualitative data synthesis and risk-of-bias analysis. Meta-analysis of tympanometry data from four eligible trials (n = 512 ears) revealed no significant difference in tympanometric normalisation between intranasal corticosteroids and control (odds ratio 1.21, 95% confidence interval 0.65–2.24).

Conclusion

Study results do not strongly support intranasal corticosteroids for Eustachian tube dysfunction. Data were limited, emphasising the need for larger, higher quality, randomised, controlled trials.
