Acute sinusitis is defined as symptomatic inflammation of the nasal cavity and paranasal sinuses lasting less than four weeks. A total of 4044 children with an average age of 8.9 years and a slight male predominance (53.8%) with CRS were identified. Of these children, 0.2% had primary ciliary dyskinesia, 4.1% had cystic fibrosis, 12.3% had an immunologic disorder, and 26.9% had AR.
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.
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. The evidence supporting use of saline irrigation is limited, but indicates possible benefits for symptom relief with minor adverse effects, including nasal burning and irritation. It is important that irrigants be prepared from sterile or bottled water, as there have been reports of amoebic encephalitis due to tap water rinses.
