Explanation:
Detailed explanation-1: -The eustachian tube is a connection between the middle ear (the space deep to the eardrum) and the back of the nose and upper throat. This structure connects the middle ear space to the outside world.
Detailed explanation-2: -Air pressure changes when airplanes take off and land. That change happens faster than your eustachian tubes can react. The same thing happens if you do deep-water diving, as water pressure quickly changes. Ear barotrauma can happen more frequently if you have congestion from a cold or allergies.
Detailed explanation-3: -The primary function of the Eustachian tube is to equalize air pressure between the atmosphere and the middle ear.
