Antibiotic Treatment: For a patient presenting with acute bacterial sinusitis characterized by fever greater than 38°C and purulent nasal discharge, antibiotic therapy should be considered, especially when there are at least three indicative features such as persistent symptoms beyond 10 days, severe localized pain, and clinical deterioration after an initial milder phase . The first-line antibiotic recommended is a narrow-spectrum agent active against common pathogens like Streptococcus pneumoniae and Haemophilus influenzae, such as phenoxymethylpenicillin, or amoxicillin-clavulanate in cases where beta-lactamase-producing organisms are suspected or clinical severity warrants broad coverage . Antibiotic use is not routinely required in uncomplicated sinusitis cases, as the majority resolve spontaneously and indiscriminate prescribing contributes to antimicrobial resistance . In cases with severe symptoms or systemic involvement, adherence to antibiotic stewardship principles is essential to optimize treatment while minimizing resistance emergence .

Adjuvant Management Strategies: Symptomatic treatment is the cornerstone of acute sinusitis management and includes analgesics such as paracetamol or ibuprofen to relieve pain and fever, and nasal saline irrigation to help clear nasal secretions and improve mucociliary clearance . Nasal decongestants, either topical or systemic, may be used short term for nasal congestion relief but should not exceed 7 days to avoid rebound congestion ,,,. Patient education is crucial to inform about the natural course of the illness, expected symptom duration, and safety-netting advice advising when to seek further medical help, such as worsening symptoms or failure to improve after three weeks . Addressing comorbid conditions like allergic rhinitis with antihistamines or intranasal corticosteroids can also reduce the risk of recurrent sinus infections and improve symptom control . Smoking cessation and avoidance of allergens or irritants can further support recovery and reduce exacerbations . For persistent or complicated cases, referral to specialist ENT services may be warranted .

Diagnostic Considerations and Stewardship: The diagnosis of bacterial sinusitis should be clinical, supported by symptom duration and severity, without routine imaging or laboratory tests . C-reactive protein (CRP) testing may aid diagnostic uncertainty but should not replace clinical judgment and must be interpreted cautiously alongside symptoms . Avoiding unnecessary antibiotics in viral sinusitis is vital to reduce antimicrobial resistance, with emphasis on shared decision-making to align patient expectations with evidence-based care .
