Sinusitis :
Sinuses are air-filled pockets located near the nose that act as a nasal pathway for the airflow; inflammation of these linings covering the sinus is known as sinusitis. This condition is divided into Acute sinusitis (4 weeks) and chronic sinusitis (more than 3 months). This condition is caused by colds or allergies, viral infections, and abnormalities in the nose, which are some of the causes of sinusitis. Headache, fever, cough, and facial pressure are the symptoms of sinusitis. Most people with sinusitis have colds that last long. Usually, for diagnosis, a sample is collected from the nose and cultured to find out the bacteria. An imaging test, nasal endoscopy, and sometimes allergy tests, as well as blood tests, can help in the diagnosis of sinusitis. Treatment involves painkillers, antibiotics, and nose drops, and surgeries are performed in severe cases where sinuses are widened to drain, conditions like deviated septum, polyps, and obstructed sinusitis. Performing surgery can help a better prognosis. If left untreated, this can lead to severe complications like meningitis, abscess, and orbital cellulitis.
