Outcome Measures for Baro-Challenge-Induced Eustachian Tube Dysfunction: A Systematic Review

Conclusion: Sixteen studies involving seven different types of ET function tests were identified. The nine-step test was the most commonly used outcome measure, with overall test sensitivity and specificity ranges of 37 to 100% and 57 to 100%, respectively. Tympanometry test sensitivity was consistently poor (0–50%) while specificity was higher (52–97%). Published accuracy data for other ET function tests and test combinations were limited. Currently, no single test can be recommended for use in clinical practice. A combination of the nine-step test with other objective tests or patient-reported measures appears most promising as a core set of outcome measures for baro-induced ETD.
