Sinus Disorders

Sinusitis, also known as a sinus infection or rhinosinusitis, is inflammation of the sinuses resulting in symptoms. Common signs and symptoms include thick nasal mucous, a plugged nose, and pain in the face. Other signs and symptoms may include fever, headaches, poor smell, sore throat, and cough. The cough is often worse at night. Serious complications are rare. It is defined as acute rhinosinusitis (ARS) if it lasts less than 4 weeks and as chronic rhinosinusitis (CRS) if it lasts for more than 12 weeks. It can be due to infection, allergies, air pollution, or structural problems in the nose. Most cases are due to a viral infection. A bacterial infection may be present if symptoms last more than ten days or if a person worsens after starting to improve. Recurrent episodes are more likely in people with asthma, cystic fibrosis, and poor immune function. X-rays are not typically needed unless complications are suspected. In chronic cases confirmatory testing is recommended by either direct visualization or computed tomography.
