Sinus is air-filled spaces located in the bones of the face and skull, including the frontal, ethmoid, sphenoid, and maxillary sinuses. They are lined with a mucous membrane that produces mucus, which helps trap and eliminate bacteria and other pollutants from the air we breathe.
Sinusitis is a condition that occurs when the sinuses become inflamed and swollen, often due to infection, allergies, or other irritants. Symptoms of sinusitis may include nasal congestion, facial pain or pressure, headaches, fever, and reduced sense of smell.
Treatment for sinusitis depends on the cause and severity of the condition. Mild cases may be managed with over-the-counter decongestants and pain relievers, such as acetaminophen or ibuprofen, to relieve symptoms. In cases caused by bacterial infections, antibiotics may be prescribed to clear the infection.
In addition to medication, self-care measures may be recommended to help relieve symptoms and promote healing. These may include saline nasal irrigation, which involves flushing the sinuses with a saline solution, or using a humidifier to add moisture to the air.
Prevention of sinusitis involves good hygiene practices, such as washing hands frequently and avoiding close contact with people who are sick. Avoiding irritants, such as cigarette smoke and air pollution, and treating underlying medical conditions, such as allergies or immune system disorders, may also help reduce the risk of developing sinusitis.
