Summary

Balloon dilation of the eustachian tube (BDET) significantly improves symptoms of Eustachian tube dysfunction (ETD) by 6 weeks. Early symptom relief is sustained, suggesting a single 6-week follow-up may be sufficient.

Background:

Eustachian tube dysfunction (ETD) presents with aural fullness, hearing loss, and tinnitus.
The Eustachian Tube Dysfunction Questionnaire (ETDQ-7) quantifies symptom burden.
Balloon dilation of the eustachian tube (BDET) is an option for chronic obstructive ETD (OETD) refractory to medical treatment.

Purpose of the Study:

To determine the optimal follow-up timing after balloon dilation of the eustachian tube (BDET).
To evaluate the sustained efficacy of BDET by assessing symptom changes at 6 and 12 weeks post-procedure.

Main Methods:

A cross-sectional study included 28 patients who underwent BDET.
Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores were collected at baseline, 6 weeks, and 12 weeks.
Repeated measures ANOVA was used to analyze changes in symptom scores.

Main Results:

A statistically significant improvement in ETDQ-7 scores was observed from baseline to 6 weeks (P < .001).
No significant additional benefit was found between the 6-week and 12-week follow-up points (P = .625).
Early symptom improvements following BDET were sustained through 12 weeks.

Conclusions:

A single 6-week follow-up may be adequate for monitoring BDET outcomes in OETD patients.
Optimizing follow-up timing can reduce patient burden and enhance healthcare resource utilization.
Further research with larger, diverse populations is recommended to validate these findings.
