Abstract
PURPOSE
This study aimed to assess the efficacy and safety of ballon dilation of the eustachian tube (BDET) in adult population suffering from Eustachian tube dysfunction (ETD).
METHODS
Following PRISMA criteria, a systematic review was conducted by searching PubMed, Cochrane, and Embase databases from January 2015 to March 2024. The primary outcomes included Eustachian Tube Score (ETS), tympanometry, and Valsalva maneuver. The quality of studies was assessed using the Quality in Prognostic Studies (QUIPS) instrument.
RESULTS
Overall, 11 studies were incorporated into the systematic review: two RCTs, three prospective investigations, and six retrospective studies. The balloon dilation in all investigations was performed using either Spiggle & Theis or Acclarent catheters for balloon dilation. There was heterogeneity across studies examining the effect of BDET on persistent ETD in terms of patient selection, period of follow-up, administration of conservative or surgical therapies, and use of assessment methods. Overall, the treatment yielded alleviation of symptoms, which either exhibited stability over time or demonstrated further improvement after an average duration of follow-up. Moreover, the incidence of complications was categorized as low and resolving spontaneously. The majority of the studies exhibited a high risk of bias related to confounding variables, and consequently, the overall risk of bias across most studies was considered high.
CONCLUSION
The findings suggest BDET holds promise for ETD treatment, reducing symptom severity with minimal complications. Nonetheless, there is a need for improved studies that adhere to established indications, methodologies, and outcomes to establish a more robust body of evidence.
