Long-term outcomes of balloon dilation demonstrate durable improvement for the treatment of Eustachian tube dysfunction (ETD)1

A recently published clinical study demonstrates Eustachian tube balloon dilation results in long-term improvement for patients with persistent Eustachian tube dysfunction.

Data demonstrated:

  • Over a mean of 29 months of follow-up, balloon dilation participants maintained the initial significant improvements over baseline using ETDQ-7 scores for symptom severity, -2.5±1.15 (47) P<0.00011
  • 83.0% of patients were satisfied with the procedure; 87.2% would recommend the procedure
