Serous Otitis Media (Fluid Behind Eardrum): Treatment Options

Serous otitis media (SOM) is middle ear effusion without acute infection. Common in children after URI; often resolves spontaneously.

Management Options

1. Watchful waiting (3 months): Most resolve; monitor hearing/development.
2. Autoinflation (Otovent): Nasal balloon device to open Eustachian tube.
3. Medications (limited evidence):
   • Decongestants/antihistamines if allergic component
   • Intranasal corticosteroids for allergic rhinitis
   • No role for routine antibiotics or oral steroids
4. Tympanostomy tubes: Indicated if:
   • Bilateral effusion >3 months with hearing loss
   • Recurrent AOM (>3 episodes/6 months or >4/year)
   • Speech/language delay
5. Balloon Eustachian tuboplasty: Emerging option for chronic Eustachian tube dysfunction.
6. Adenoidectomy: If adenoid hypertrophy contributes (often combined with tubes).

When to Refer

• Persistent effusion >3 months
• Hearing loss >20 dB
• Structural abnormalities (cleft palate, Down syndrome)
• Failed medical management

Adults with new-onset SOM need nasopharyngeal evaluation to rule out malignancy.
