Systematic review highlights effectiveness and safety of balloon dilation for eustachian tube dysfunction, suggesting benefits despite mixed outcomes in audiometry.
Key Points
Balloon dilation of the eustachian tube effectively improves tympanometry results, especially within 6 weeks.
The ETDQ-7 questionnaire indicated symptom improvement following the balloon dilation procedure.
Safety analysis showed rare complications associated with the procedure performed under general or local anesthesia.
Long-term efficacy data remains limited, notably regarding its impact on pure tone audiometry results.
