The Eustacian tubes allow the pressure on inside the ear and out to remain equal.
The eustacian tube connects the inner ear to the back of the throat.
It equalizes the pressure between the middle ear and the atmosphere. This is what causes your ears to "pop" when you change altitude.

Betahistine actually targets the inner ear, but since it is used as an inhalant, the sinus cavities are linked to the middle ear by the Eustacian tubes which deliver the histamine (Betahistine) into the middle ear where it dilates the blood vessels within the middle ear which can relieve pressure from excess fluid and act on the smooth muscle. This is in turn can alleviate the symptoms of MÃ©niÃ¨re's disease, which involves the inner ear and is experienced as dizzyness (vertigo).
