Sinusitis is a common disease in childhood and puberty with significant morbidity and the potential for serious complications. There are two types of acute sinusitis: viral and bacterial. Viral sinusitis develops during a cold. Some children with certain predisposing diseases may develop forms of chronic sinusitis, which is usually not of infectious origin. Children and adolescents may have nonspecific symptoms: fever, nasal congestion, nasal secretion. Less common difficulties include bad breath, reduction sense of smell, and periorbital edema. Headaches and facial pain are rare in children. The most common symptoms are headache, tenderness in the facial area and a stuffy nose.
