Could you please explain me the role of allergies in the function of the eustachian tube and the state of the middle ear chamber? As potential effectiveness of allergy happens while treating a chronic case of eustachian tube dysfunction, mild approaches to treat this proved ineffective.
Welcome to iclinq.com.
Eustachian tube (ET) opening allows the passage of air into the middle ear. The middle ear is a chamber that has to maintain a certain volume of air in it for normal hearing function. For the air to go away from the middle ear, it requires further air flow from the eustachian tube.
Due to various metabolic activities, there is always a negative balance of air in the middle ear due to air absorption by blood vessels.
As for as eustachian tube is concerned, its opening is in the throat, and it is guarded by muscles and cartilages. Whenever any inflammation occurs in the throat or behind the nose, the mucosal covering of the ET gets thickened. Allergy can also cause mucosal inflammation and obstruction of ET.
The reversal of ET function depends on the success rate of it.
