Features & Benefits

Designed for safety

The first product of its kind, ACCLARENT AERA® was specifically designed for the Eustachian tube anatomy with flexibility to reach the source of the problem in a minimally invasive way.

Mechanism of action

Pathology lies within the cartilaginous segment of the Eustachian tube. Histopathology research has demonstrated that balloon dilation may:

  • Shear or crush portions of the epithelium; usually sparing the basal layer and allowing for rapid healing
  • Crush lymphocytes and lymphoid follicle
  • Combined, these effects reduce overall inflammatory burden and may be the underlying reason for lasting clinical improvement in Eustachian tube dilation and ventilation.2

Proven effective and safe for ETD patients

ACCLARENT AERA® was studied in the only prospective, multicenter, randomized clinical trial of balloon dilation procedures.3
