Repeat Eustachian Tube Balloon Dilation Outcomes in Adults With Chronic Eustachian Tube Dysfunction

Abstract

Objective With increased focus on surgical management of the eustachian tube, clarifying management decisions benefits patients and surgeons. In this study, we examine the value of repeating the balloon dilation of the eustachian tube (BDET) procedure in patients who did not improve after the initial BDET. Study Design Level IV retrospective review of 145 BDETs performed on 86 patients between January 1, 2014, and May 1, 2019, identified 10 patients who underwent BDET more than once. Setting Managed care community otolaryngology practice. Methods Demographic and outcome data were collected on both single and repeat BDET cohorts. Results The Eustachian Tube Dysfunction Questionnaire 7 (ETDQ-7) was used as the primary outcome measure when comparing single vs repeat BDET cohorts. Generally, the 2 cohorts were similar in terms of sex and age distribution. Tobacco use and radioallergosorbent test–positive results were greater proportionally in the repeat BDET cohort. Preoperative ETDQ-7 scores were similar in both cohorts. Single BDET patients overall showed significant improvement in ETDQ-7 scores. ETDQ-7 scores for repeat BDET patients who did not improve after the first procedure similarly did not demonstrate improvement after the second procedure. Conclusions Inevitably, some patients will not improve after an initial BDET procedure. The utility of a repeated BDET procedure should be considered in determining how to manage such failures. The results of this limited study suggest that patients who fail to improve meaningfully on ETDQ-7 scores after the initial procedure are unlikely to show substantial improvements after a repeated procedure.

“…This suggests that the infiltration of fibrous scar tissue into partial defects of the fractured cartilage is delayed owing to SRL but not replaced by elastic cartilage. The lack of response to repeat ETBD after the failure of primary ETBD 40 may be owing to the increased fibrotic area of the fractured cartilage. Infiltration of fibrous scar tissue may interfere with cartilage expansion and contraction and result in additional defects 41 , 42 .…”
