What is the treatment for rhinosinusitis in a 2-year-old?

Treatment of Rhinosinusitis in a 2-Year-Old Child

For a 2-year-old with rhinosinusitis, saline nasal irrigation and symptomatic treatment should be the first-line approach, with antibiotics reserved only for cases showing clear signs of bacterial infection or worsening symptoms.

Diagnosis Considerations

Before initiating treatment, it's important to distinguish between different types of rhinosinusitis:

• Viral rhinosinusitis (common cold): Most common, self-limiting
• Post-viral rhinosinusitis: Symptoms persisting beyond 10 days without improvement
• Acute bacterial rhinosinusitis: Characterized by:
  • Persistent symptoms >10 days without improvement
  • Severe symptoms with high fever (≥39°C/102.2°F) for at least 3 consecutive days with purulent discharge
  • Worsening symptoms after initial improvement ("double sickening")

First-Line Treatment

1. Saline Nasal Irrigation/Lavage

   • Helps remove debris and reduce tissue edema 1, 2
   • Can be performed using infant-appropriate saline drops or spray
   • The one pediatric study showed improvement in nasal airflow, quality of life, and symptom scores 1

2. Symptomatic Relief

   • For pain/fever: Acetaminophen or ibuprofen as needed 2
   • Adequate hydration and humidification of the environment

Second-Line Treatment (If Symptoms Persist or Worsen)

1. Intranasal Corticosteroids

   • May be beneficial in reducing mucosal swelling and inflammation 1, 2
   • The European Position Paper on Rhinosinusitis (EPOS) 2020 notes that evidence for their use in children with acute post-viral rhinosinusitis is of very low quality 1
   • Use age-appropriate formulations and doses

2. Antibiotics

   • Only indicated if:
     • Symptoms persist beyond 10 days without improvement
     • Severe symptoms with high fever and purulent discharge
     • Worsening symptoms after initial improvement
   • First-line antibiotic (if needed):
     • Amoxicillin-clavulanate (80 mg/kg/day in three doses) 1
     • Alternative: Cefpodoxime-proxetil (8 mg/kg/day in two doses) 1
     • Duration: 7-10 days typically 1

Treatments to Avoid

1. Antihistamines

   • Not recommended unless there is a clear allergic component 1, 2
   • One study showed no additive effect in post-viral rhinosinusitis 1

2. Oral Decongestants

   • Limited evidence for efficacy in children this young
   • Potential for adverse effects 2

3. Systemic Corticosteroids

   • EPOS 2020 advises against systemic corticosteroids in acute post-viral rhinosinusitis due to potential harm and limited evidence 1

When to Consider Referral

• Presence of alarm symptoms (periorbital edema/erythema, displaced globe, severe headache, visual changes, signs of meningitis) requires immediate referral 1
• Failure to improve after appropriate treatment for 7 days 2
• Recurrent episodes suggesting possible underlying conditions

Important Considerations for Young Children

1. Rhinosinusitis in children is primarily a self-limiting condition

   • Most children "grow out" of recurrent upper respiratory issues by age 8-10 3
   • Conservative management is generally preferred over surgical approaches

2. Anatomical differences in young children

   • Sinuses are not fully developed at age 2
   • Maxillary sinusitis is the most common form and is typically only observed in children aged 3 years or older 1

3. Potential underlying conditions

   • Consider adenoid hypertrophy as a contributing factor 3
   • Evaluate for allergic rhinitis if symptoms are recurrent

Follow-up

• Reassess after 72 hours of treatment 2
• If symptoms worsen at any time or fail to improve after 7 days of appropriate treatment, reevaluation is necessary

Remember that rhinosinusitis in children is primarily a self-limiting condition, and "watchful waiting" with supportive care is often the most appropriate approach 3.
