Sinusitis (acute)


Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting <4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, by additional malaise and fever. The diagnosis is usually made clinically (on the basis of history and examination, but without radiological or bacteriological investigation). Clinically diagnosed acute sinusitis is less likely to be caused by bacterial infection than acute sinusitis confirmed by radiological or bacteriological investigation.[1] In this review, we have excluded studies in children, in people with symptoms for >4 weeks (chronic sinusitis), and in people with symptoms after facial trauma. We have made it clear in each section whether we are dealing with clinically diagnosed acute sinusitis or acute sinusitis with clinical symptoms that have also been confirmed by bacteriological or radiological investigation, because the effects of treatment may be different in these groups.
