ETD Treatment – Acclarent Aera™ System
The ACCLARENT AERA™ Eustachian Tube Balloon Dilation System is the first device in the US indicated to dilate the Eustachian tube, providing relief for ETD.
The Eustachian tube is a narrow tube which links the back of the nose to the middle ear. It is normally closed but opens when we swallow, yawn or chew. It has three main functions: to protect the middle ear from sources of disease, to ventilate the middle ear, and to help drain secretions away from the middle ear.
What is ETD?
Eustachian tube dysfunction (ETD) is the inability of the Eustachian tube to adequately perform these functions and failure of the valve of the Eustachian tube to open and/or close properly. Normally, the Eustachian tubes are working properly so you don’t notice them at all. Anything that prevents the tube from opening can cause Eustachian tube dysfunction. Eustachian tube dysfunction may occur when the mucosal lining of the tube is swollen, or does not open or close properly. It can occur after the start of a cold and other nose, sinus, ear and throat infections.
What are the symptoms?
When they are not working properly, the patient can possibly feel the following symptoms:
- Muffled hearing
- Fullness of the ear
- Pain in the ear
- Inability to equilibrate middle ear (ME) pressure
Further complications from untreated ETD:
- Damage to the middle ear and the eardrum.
- Otitis media with effusion
- Atelectasis of the ME
- Aadhesive otitis
- Perforation of eardrum
When using the Acclarent Aera™ system, our doctors use a catheter 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 this tube, which may help restore proper function. After the Eustachian tube is dilated, we deflate and remove the balloon.
- Clinical studies demonstrated a 99.7 percent technical success rate in Eustachian tubes dilated.
- Studies also found a greater rate of tympanogram normalization than control subjects treated with medical management alone (51.8 vs. 13.9 percent), as well as a greater improvement in quality of life measures.
- 56.1% vs. 8.5% improvement in the Quality of Life measure from the Eustachian Tube Dysfunction Questionnaire (ETDQ-7).
- Zero reported serious device- or procedure-related adverse events.
