Treatment of Serous Otitis Media (Otitis Media with Effusion)
Initial Management: Watchful Waiting is the Standard Approach
The cornerstone of treatment for serous otitis media (otitis media with effusion, OME) is watchful waiting for 3 months from diagnosis, as 75-90% of cases resolve spontaneously without intervention. 1, 2
Who Should Receive Watchful Waiting
- All children without risk factors should be managed with observation for 3 months from the date of effusion onset or diagnosis 1, 2
- During this period, monitor with pneumatic otoscopy or tympanometry at clinician discretion 1
- Inform parents that the child may experience reduced hearing (especially if bilateral) until effusion resolves 1
- Recommend strategies to optimize the listening environment: speaking in close proximity, facing the child, speaking clearly, repeating when misunderstood, and providing preferential classroom seating 1
Nasal Balloon Auto-Inflation During Observation
- Use nasal balloon auto-inflation during the watchful waiting period due to its low cost, absence of adverse effects, and proven efficacy (NNT = 9 for clearing effusion at 3 months) 2
- This intervention showed that after 8 weeks, only 4 of 45 children required tympanostomy tubes 2
Medical Therapies: What NOT to Use
Antihistamines, decongestants, oral corticosteroids, intranasal corticosteroids, and antibiotics are all ineffective for OME and should NOT be used. 1, 2
Specific Medications to Avoid
- Antihistamines and decongestants: Cochrane meta-analysis showed no benefit (RR 0.99,95% CI 0.92-1.05) 1, 2
- Intranasal corticosteroids: No improvement in symptoms or middle ear function 2
- Oral corticosteroids: No benefit within 2 weeks; short-term benefit when combined with antimicrobials becomes nonsignificant after several weeks 1
- Adverse effects include behavioral changes, increased appetite, weight gain, adrenal suppression, fatal varicella infection, and avascular necrosis of the femoral head 1
- Antimicrobials: Do not have long-term efficacy; adverse effects include rashes, vomiting, diarrhea, allergic reactions, bacterial resistance, and societal transmission of resistant pathogens 1, 2
- Prolonged or repetitive courses of antimicrobials or steroids are strongly contraindicated 2
Exception: Topical Decongestants for Acute Symptoms
- Short-term topical decongestants (oxymetazoline or xylometazoline) may be used for acute nasal congestion associated with ETD, but limit to 3 days maximum to avoid rhinitis medicamentosa 2
- These are appropriate only for acute, short-term management, not for OME treatment 2
When to Obtain Hearing Testing
Obtain age-appropriate hearing testing if OME persists for 3 months or longer. 2
- OME causes an average hearing loss of 25 dB HL at the 50th percentile, with approximately 20% of ears exceeding 35 dB HL 2
- Reevaluate every 3-6 months with otologic examination and audiologic assessment until effusion resolves, significant hearing loss is identified, or structural abnormalities develop 2
Surgical Intervention: Tympanostomy Tubes
Tympanostomy tube insertion is the preferred initial surgical procedure for persistent OME lasting 3 months or longer with documented hearing loss or structural changes. 2
Indications for Tympanostomy Tubes
- Bilateral effusions for ≥3 months with mild hearing loss (16-40 dB HL) 2
- Chronic OME with structural changes of the tympanic membrane (retraction, atelectasis) 2
- Type B (flat) tympanogram indicating persistent fluid or negative pressure after 3 months 2
- Tubes provide hearing improvement of 6-12 dB while patent and clear effusion for up to 2 years 2
- High-level evidence shows benefit for hearing and quality of life for up to 9 months 2
Critical Timing
- Do NOT insert tympanostomy tubes before 3 months of documented OME 2
- There is no evidence of benefit before 3 months, and it exposes the patient to unnecessary surgical risks 2
- Tympanostomy tubes have no evidence of beneficial effect on language development 2
Age-Specific Surgical Considerations
Children Under 4 Years
- Recommend tympanostomy tubes alone 2
- Do NOT perform adenoidectomy unless a distinct indication exists other than OME (such as nasal obstruction or chronic adenoiditis) 2
Children 4 Years and Older
- Consider tympanostomy tubes, adenoidectomy, or both 2
- For repeat surgery: Adenoidectomy plus myringotomy (with or without tubes) is recommended unless cleft palate is present 2
- Adenoidectomy reduces the need for ventilation tube re-insertions by approximately 10% and confers a 50% reduction in the need for future operations 2
Special Populations Requiring Earlier or More Aggressive Intervention
At-risk children may receive tympanostomy tubes earlier than the standard 3-month waiting period. 2
High-Risk Groups
- Children with severe visual impairments: They depend on hearing more than children with normal vision; any decrease in hearing may significantly compromise language development 1
- Children with Down syndrome: Require hearing assessments every 6 months starting at birth and otolaryngologic evaluation for recurrent AOM and OME due to poor eustachian tube function 2
- Children with cleft palate: Require management by a multidisciplinary team and continued monitoring throughout childhood, even after palate repair, due to nearly universal occurrence of OME 2
- Children with developmental disabilities: Require closer monitoring as they may lack communication skills to express pain or discomfort 2
- Children with craniofacial syndromes 2
Monitoring for At-Risk Children
- These children should be considered more vulnerable to OME sequelae and may warrant earlier surgical intervention 1, 2
- The severity of OME correlates with lower IQ, hyperactive behavior, and reading defects 2
Allergy Management
For patients with OME secondary to allergic rhinitis, treat the underlying allergies. 2
- Intranasal corticosteroids are first-line treatment for allergic rhinitis itself (not for OME) 2
- Second-generation antihistamines for sneezing and itching associated with allergic rhinitis 2
Post-Treatment Monitoring
- After tympanostomy tube placement, evaluate children within 3 months and then periodically while tubes remain in place 2
- Educate caregivers about tube function duration, follow-up schedule, and how to detect complications 2
- Water precautions may be necessary, particularly for swimming in non-chlorinated water or dunking head during bathing 2
Management of Tube Otorrhea
- For ear infections with tubes in place: Antibiotic ear drops (ofloxacin or ciprofloxacin-dexamethasone) are the treatment of choice, applied twice daily for up to 10 days 2
- Quinolone ear drops have not shown ototoxicity and are preferred over systemic antibiotics 2
- Oral antibiotics are generally unnecessary unless the child is very ill or the infection doesn't respond to ear drops 2
- Do not use antibiotic eardrops frequently or for more than 10 days at a time to avoid yeast infections of the ear canal 2
