Management of acute and chronic sinusitis.

Sinusitis is a common condition for which patients often consult the community pharmacist. It is, however, challenging to differentiate between common forms of sinusitis as they have nearly identical clinical representations. This review article provides an overview of sinusitis, classification, differential diagnosis between viral sinusitis, bacterial sinusitis and chronic rhinosinusitis, therapeutic management, patient education and patient referral guidelines. In addition, the recently updated guidelines on sinusitis published by the American Academy of Otolaryngology-Head and Neck Surgery Foundation (2015), the European position paper on rhinosinusitis and nasal polyps, EPOS 2012 and the Canadian guidelines for acute bacterial rhinosinusitis (2014) will be reviewed.
