Management of Sinusitis

Acute Sinusitis Management

The American Academy of Allergy, Asthma, and Immunology recommends amoxicillin as the first-line antibiotic for uncomplicated acute bacterial sinusitis, with a standard course of 10-14 days for acute disease 1, 2
Acute sinusitis typically presents as a persistent upper respiratory tract infection (10-14 days without improvement) or with severe symptoms (high fever and purulent nasal discharge) 1
Symptoms of acute sinusitis include nasal congestion, purulent rhinorrhea, postnasal drainage, facial/dental pain, headache, and cough 1
For patients allergic to or intolerant of amoxicillin, alternatives include cephalosporins, macrolides, and quinolones 3
If no improvement after 3-5 days, switch to a different antibiotic 4

Chronic sinusitis is defined as symptoms lasting longer than 8 weeks, and recurrent sinusitis consists of 3 or more episodes of acute sinusitis per year 1
The American Academy of Allergy, Asthma, and Immunology recommends intranasal corticosteroids as a first-line therapy for chronic sinusitis 2
Daily high-volume saline irrigation is recommended for chronic sinusitis, and for chronic infectious sinusitis, longer duration of antibiotic therapy may be required 2, 5
For patients with nasal polyps, consider a short course of systemic corticosteroids or doxycycline 2

Consider surgical intervention for medically resistant sinusitis, and functional endoscopic sinus surgery may result in significant improvement for localized persistent disease within the ostiomeatal complex 2

Overdiagnosis of sinusitis and unnecessary antibiotic use is common, and appropriate criteria for antibiotic use include symptoms for 10-14 days or severe symptoms including fever with purulent nasal discharge and facial pain 2
Patients should be instructed to complete the full course of antibiotics to prevent relapse 4
Failure to address underlying factors (allergies, anatomical abnormalities) may lead to recurrent or chronic sinusitis 3
