Revision as of 00:44, 16 August 2020

Sinusitis lasting for at least 12 weeks
May or may not be infectious

The same bacteria as in acute bacterial sinusitis may be present, especially during acute exacerbations
Other bacteria include Staphylococcus aureus, Gram-negative bacteria, anaerobes, coagulase-negative staphylococci, and Corynebacterium

Risk Factors

Systemic factors: viral infection, allergic inflammation, cystic fibrosis, immune disorders, ciliary dyskinesia, tobacco smoke
Mechanical factors: choanal atresia, deviated septum, nasal polyps, foreign body, tumour, ethmoid bullae
Local factors: facial trauma, swimming and diving, rhinitis medicamentosa, nasal intubation
