If the fluids remained in the middle ear they could accumulate to a dangerous point and actually burst the eardrum. The tube helps to keep air pressure in the ear at the same level as our surrounding environment and that keeps our hearing working normally. Small hairs in the tube also perform an important function: they collect any bacteria that enter the tube and make sure that it is “drained out” with mucous. That is how the tube works correctly.

When the tube is not doing its task correctly an infection can result. If the tube becomes blocked, fluids can gather in the middle ear. Any bacteria that were there and unable to drain will multiply. If the small hairs that line the tube are affected by a cold or virus they will not be able to perform their function and the bacteria will not be flushed out. Blockage can result from colds, exposure to cigarette smoke, allergic reactions, rapid changes in air pressure (being in an airplane landing and or taking off) all could cause the tube to close. These changes could also produce a “vacuum” condition in the air space of the middle ear that can suck more bacteria into the area. Regrettably, even air pollution can have a negative effect on the Eustachio Tube.

Ear infections usually occur when the weather turns colder and generally effect children under the age of two. It is a very common and painful occurrence for young children.

Known as otitis media, the infection takes place in the space immediately behind the eardrum. Contrary to common belief, water from outside sources (bath or shower) is not physically able to enter this space and cause an infection. However, the infection is caused by bacteria that get into the middle ear by way of the Eustachian Tube, the long narrow tube that goes from the rear of the throat to the middle ear area.

The tube allows for the small amount of fluid that naturally appears in the middle ear to “drain” down the back of the throat.
