What causes negative pressure in the ear?

When the eustachian tube does not open to allow the middle ear space to ventilate for a prolonged period of time, negative pressure is generated in the middle ear space as the mucous membranes absorb the air from the middle ear.

What is the best way to treat eustachian tube dysfunction?

A common course of treatment for Eustachian tube dysfunction is the use of decongestants or antihistamines. In some cases, this treatment may make the condition worse. If decongestants or antihistamines do not provide relief, contact your doctor. You may need to see an ear, nose and throat specialist for treatment.
