Diagnosis is typically confirmed through a combination of otomicroscopy, which may reveal a dull tympanic membrane with reduced mobility, and tympanometry, a test that measures the compliance of the eardrum and verifies the presence of negative pressure or fluid behind it. Audiometric Findings and Assessment Audiometric testing plays a crucial role in quantifying the impact of the effusion on hearing function.

When the tube remains obstructed, negative pressure develops in the middle ear, drawing fluid from the surrounding vascular tissues into the cavity. For persistent cases, particularly those lasting beyond three months or causing significant hearing deficits, interventions such as the insertion of tympanostomy tubes (grommets) become the standard of care to ventilate the middle ear and restore conductive function.
Patients, especially children, may exhibit behaviors such as asking for repetition, turning up the volume on electronic devices, or displaying inattentiveness, which are frequently misattributed to behavioral issues rather than a physiological deficit. In children, the anatomical structure of the Eustachian tube is more horizontal and shorter, predisposing them to poor drainage following upper respiratory infections.

The prolonged presence of this fluid provides a medium for bacteria and viruses to linger, increasing the risk of recurrent acute infections and creating a cycle of inflammation and further dysfunction. Bilateral otitis media with effusion represents a persistent accumulation of non-infected fluid within the middle ear space, affecting both ears simultaneously.
