Acute Sinusitis Management

Introduction to Treatment Options

The American Academy of Otolaryngology-Head and Neck Surgery recommends intranasal corticosteroids as adjunctive therapy in acute sinusitis, which may provide modest benefits, increasing symptom improvement rates from 66% to 73% after 15-21 days (number needed to treat of 14) 1
Intranasal corticosteroids have anti-inflammatory effects, including decreased vascular permeability, inhibition of inflammatory mediators, and reduction of inflammatory cell infiltration 2

Consider intranasal corticosteroids as adjunctive therapy to antibiotics in acute bacterial sinusitis, which may have modest short-term benefit for symptom relief when combined with antibiotics (number needed to treat of 7) 1
Prescription options for intranasal corticosteroids include mometasone, fluticasone, flunisolide, and budesonide, while over-the-counter options include triamcinolone acetonide 1
Analgesics (NSAIDs, acetaminophen) are recommended for pain relief 1
Saline irrigation is recommended for symptomatic relief, with hypertonic saline (3-5%) potentially having superior benefit to isotonic saline 1

Systemic corticosteroids should generally be avoided due to limited evidence of benefit and potential adverse effects, with no benefit over placebo when used as monotherapy 1
Decongestants have unknown effects on acute sinusitis symptoms 1
Guaifenesin (mucolytic) has unknown effects on acute sinusitis symptoms 1
Antihistamines should not be used unless there is a clear allergic component, as their efficacy is questionable 1, 3

A multi-modal approach including intranasal corticosteroids, saline irrigation, and mucolytics/expectorants is recommended for acute sinusitis management 4
Consider extending antibiotic treatment duration to 3-4 weeks, and consider antihistamines only if allergic rhinitis is present 4

Avoid using systemic steroids as monotherapy, overlooking contributing factors like smoking or GERD, and prolonged use of decongestants (limit to 5 days) 4
Avoid using antihistamines in non-allergic patients, and avoid using narcotics for pain management (rarely necessary and should be discouraged) 3, 1
