Eustachian Tube Balloon Dilation
Persistent Eustachian tube dysfunction (ETD) is the inability of the Eustachian tube to adequately perform its functions and failure of the Eustachian tube to open and/or close properly.1
With Eustachian Tube Balloon Dilation, a small balloon catheter is used to insert a small balloon through the patient’s nose and into the Eustachian tube. Once inflated, the balloon opens up a pathway for mucus and air to flow through the Eustachian tube, which may help restore proper function. After the Eustachian tube is dilated, the balloon is deflated and the catheter is removed.2
The following diagrams outline the balloon dilation process.
Step 1: The ACCLARENT AERA® Eustachian Tube Balloon Dilation System is introduced into the Eustachian tube under direct visualization.
Step 2: The ACCLARENT AERA® balloon is then inflated for 2 minutes, applying controlled radial pressure to the epithelial layer. The shearing or crushing of portions of the epithelium, sparing the basal layer, allows for rapid healing.
Step 3: After dilation, the balloon is deflated and withdrawn from the Eustachian tube
