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. 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.

This condition frequently occurs following repeated or chronic episodes of inflammation, leading to a dysfunction of the Eustachian tube, which normally regulates pressure and drains mucus. The stagnant fluid creates a conductive barrier that impairs the vibration of the tympanic membrane and ossicles, resulting in a measurable hearing loss that can fluctuate or become chronic if left unaddressed.
In many cases, a period of active observation is recommended, as effusions can resolve spontaneously within three months. Bone conduction thresholds usually remain within normal limits, distinguishing this from sensorineural loss.

During this watchful waiting phase, addressing modifiable risk factors such as managing allergies or removing adenoidal tissue may be advised. When the tube remains obstructed, negative pressure develops in the middle ear, drawing fluid from the surrounding vascular tissues into the cavity.
