The role of CT scan in rhinosinusitis by Defby Ulfandy
Sinusitis is rarely life threatening, but the close proximity of the paranasal sinuses to the central nervous system, the multiple fascial plains of the neck, and the associated venous and lymphatic channels can lead to serious complications. An estimated more than 30 million patients in the United States have sinus disease. An estimated 5-10% of Upper respiratory infectios (URIs) in children are related to sinusitis, while up to 10% of URIs in adults are related to sinusitis. Sinusitis is rare in children younger than 1 year because the sinuses are poorly developed before that age. A viral infection associated with the common cold is the most frequent etiology of acute sinusitis. Only a small percentage (as low as 2%) of viral sinusitis cases are complicated by bacterial sinusitis. The challenge is to differentiate a simple URI and allergic rhinitis from sinusitis. Rhinosinusitis is a common condition seen in the United Kingdom and many other countries, also in Indonesia. Presenting symptoms can be varied and often vague.
