What is Chronic sinusitis?

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 can be due to infection, allergies, air pollution, or structural problems in the nose. Most cases are due to a viral infection. --> 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.

Some cases may be prevented by hand washing, avoiding smoking, and immunization. Pain killers such as naproxen, nasal steroids, and nasal irrigation may be used to help with symptoms. --> If after a further seven days there is still no improvement antibiotics may either be recommended or changed. In those in who antibiotics are used, either amoxicillin or amoxicillin/clavulanate is recommended first line. Surgery may occasionally be used in people with chronic disease.

Sinusitis is a common condition. It affects about between 10% and 30% of people each year in the United States and Europe.
