• Middle ear effusion (also known as otitis media with effusion, OME) is the buildup of fluid behind the eardrum without signs of infection.

• It often happens after a cold, ear infection, or allergies.

• While it's more common in children, adults can also experience it.

The main reason is that tube helps drain the middle ear to nose cavity doesn't work properly and that can be because of :

• Recent ear infection (fluid can remain after the infection clears)

• Common Colds or upper respiratory infections

• Allergies causing swelling or fluid buildup

• Changes in pressure (such as during air travel)

• Feeling of fullness or pressure in the ear

• Muffled hearing or mild hearing loss

• Popping or crackling sounds when swallowing or yawning

• Balance issues in some cases

• Usually no fever or ear pain, unless there's an active infection

• ENT consultation with Hearing test to confirm and define severity of fluid

• Nasal decongestants, antihistamines, or allergy medications may help if allergies are involved

• Nasal saline to reduce congestion

• In children with frequent or long-lasting fluid, ear tubes may be placed surgically to help drain fluid and prevent future buildup and recover hearing diminished

• If the fluid lasts more than 3 months

• If there is noticeable hearing loss or speech delays in children

• If symptoms worsen or new symptoms develop, such as pain or fever
