ACCLARENT AERA® Eustachian Tube Balloon Dilation System Patient Selection

Identifying appropriate patients.  Ear discomfort can be caused by a variety of conditions.

Clinical proven study with patients with persistent Eustachian tube dysfunction (ETD) 

Patient inclusion criteria used to determine if a patient was a potential candidate with persistent ETD for admission into "A Randomized Clinical Study of Safety and Efficacy for the Eustachian Tube Balloon Catheter (ELLIOTT)”1

Clinical evidence study methodology 

The study was a prospective, multicenter, randomized, controlled trial to demonstrate superiority of the Eustachian tube balloon dilation with Eustachian tube balloon catheter in  conjunction with medical management compared to medical management alone. 

  • Subjects age 22 and older diagnosed with persistent ETD. 
  • Persistent ETD is defined by patient-reported symptoms of ETD for 12 weeks or greater. 
  • Failure of medical management consisting of either a minimum of 4 weeks of continuous daily usage of any intranasal steroid spray or a minimum of one completed course of an oral steroid. 
  • Patients were required to have a computed tomography (CT) scan to confirm absence of internal carotid artery (ICA) dehiscence in the ET lumen. 
  • An abnormal tympanometry (type B or C) after failed medical management. 
  • Demonstrated symptomatic dysfunction as documented through a validated quality of life instrument (ETDQ-7) with a score ≥ 2.1 after failed medical management. 

It is ultimately up to the healthcare provider's discretion to diagnose appropriate patients.
