 The Eustachian tube is a tube that connects the back of the nose with the ear. Its job is to keep the pressure on the inside of the eardrum close to the pressure outside the eardrum, so that the eardrum can vibrate properly. Usually this tube is closed, but it opens briefly during swallowing. In the condition called patulous eustachian tube, this tube is open all the time. This is a benign condition but it can be very bothersome to patients.1 The incidence of patulous Eustachian tube dysfunction is about 0.3-6.6 of the population. However, about 15 of the people who have this condition are bothered enough by it that they seek medical attention. This condition is more common in females than males and is more common in adults than children.1
