Otitis media with effusion

Otitis media with effusion is middle-ear fluid persisting without signs of acute infection, most often in young children after an upper respiratory infection or acute otitis media, managed mainly with observation and reserving tympanostomy tubes for persistent hearing loss.

What this article covers

  • Overview

    Fluid without infection: otitis media with effusion (OME, also called serous otitis media or "glue ear") is a collection of fluid in the middle ear space without acute signs or symptoms of infection…

  • Epidemiology

    Age concentration: occurs predominantly in young children, frequently in the weeks after an episode of acute otitis media or an upper respiratory infection.

  • Risk factors

    Young age: infants and toddlers have narrower, straighter eustachian tubes that drain and ventilate the middle ear poorly compared with older children and adults.

  • Pathophysiology

    Eustachian tube obstruction: nasopharyngeal inflammation (from a preceding URI or eustachian tube dysfunction) obstructs the eustachian tube.

  • Clinical features

    Painless conductive hearing loss or aural fullness is the hallmark: many children are otherwise asymptomatic, and the presentation is muffled hearing, decreased attentiveness, or painless pressure in…

  • Differential diagnosis

    Acute otitis media: bulging, erythematous TM with loss of the light reflex, fever, and acute otalgia; the bulging, erythematous drum with pain and fever is what excludes OME.

  • Diagnosis

    This is a clinical diagnosis made by otoscopy: the diagnosis is established by finding middle-ear fluid (a dull or retracted TM with visible fluid, an air-fluid level, or bubbles) with reduced or…

  • Management

    First, observe: most effusions resolve spontaneously without treatment, so the initial approach for the great majority of children is watchful waiting with reassessment; because OME occurs without…

  • Complications

    Conductive hearing loss: the most common consequence, and in young children persistent or recurrent hearing loss can impair speech and language development if untreated.

  • Prognosis

    Favorable in most children: the large majority of effusions resolve spontaneously within the 3-month observation window as eustachian tube function matures and any preceding URI or AOM resolves.

  • Prevention

    Avoid cigarette smoke exposure: secondhand smoke is an established risk factor for otitis media, so eliminating household smoke exposure reduces risk.
