It is a term frequently heard in childhood diseases. By definition, it is the presence of fluid in the space behind the eardrum. Most of the time, the liquid in this recipe is not inflammatory. But it potentially carries a risk of middle ear infection. The fluid behind this membrane is actually produced by the glands of that region and circulates with the help of the Eustachian tube that connects to the nasal region.

Fluid accumulation here is mostly due to diseases that will prevent the regular operation of this pipe. Allergic manifestations in the nasal region, especially at the points where this tube is opened, which will cause adenoid, nasal congestion and mucosal edema, may lead to the formation of this fluid chronically.

Temporary fluid accumulation mostly occurs in nasal congestion due to upper respiratory tract infections. Diagnosis is made by ear examination and tympanometric examination. Upper respiratory tract infections that are not treated early lead to inflammation of this fluid and middle ear infections later on.

Temporary ambient pressure changes can also affect the operation of the Eustachian tube. In-cab pressure in airplane journeys and altitude changes in bus and car journeys can be given as examples.

Although this problem is rarer in adult patients, it is important because it brings to mind tumoral diseases of the nasal region. Treatment is by removing the factor that prevents the Eustachian tube from working. Adenoid operation, allergic condition causing nasal congestion and elimination of intranasal curvature and tube applications that can be added to these, which will provide ventilation of the back of the eardrum, are listed as interventions to be applied. Information about these initiatives will be explained in the related topic.
