Explanation
Otitis media is an inflammation of the middle ear. The eustachian tubes equalise the pressure between the middle ear cavity and the outside mucus to drain out of the middle ear cavity. Inflammation of the middle ear causes the tubes to close, causing the fluid to become trapped. Bacteria travel from the back of the nose through the fluid in the eustachian tube directly into the middle ear cavity and multiply in the fluid.
