Acute sinusitis is defined as symptomatic inflammation of the nasal cavity and paranasal sinuses lasting less than four weeks. The term "acute sinusitis" is preferred to "sinusitis" since inflammation of the sinuses rarely occurs without concurrent inflammation of the nasal mucosa.In the 3244 patients are registered with acute sinusitis and in the TP 5424 CMR: The absolute incidence of (acute) sinusitis is 5191 (18.8 per 1000 patient years). Regarding an odds ratio of 5.58, having nasal polyps is strongest related to rhinosinusitis compared to the other evaluated comorbidities.
The most common etiology of ARS is a viral infection associated with the common cold. Viral rhinosinusitis is complicated by acute bacterial infection in only 0.5 to 2.0 percent of episodes uncomplicated acute viral rhinosinusitis (AVRS) typically resolves in 7 to 10 days. Acute bacterial rhinosinusitis (ABRS) may also be a self-limited disease. Rarely, patients with untreated bacterial disease may develop serious complications. This topic will address the treatment of acute sinusitis.
Symptomatic therapy is indicated for both acute viral rhinosinusitis (AVRS) and acute bacterial rhinosinusitis (ABRS). Analgesics — Analgesics such as non-steroidal anti-inflammatories and acetaminophen are used for pain relief.Saline irrigation — Mechanical irrigation with buffered, physiologic, or hypertonic saline may reduce the need for pain medication and improve overall patient comfort, particularly in patients with frequent sinus infections. Intranasal glucocorticoids — the theoretic mechanism of action for intranasal glucocorticoids (corticosteroids) is a decrease in mucosal inflammation that allows improved sinus drainage.
