The infection of the sinuses (cavities situated inside the skull, which are filled with air), also known as sinusitis is produced by bacteria, fungus and sometimes by pollutants and allergic factors. It can be acute or chronic and can lead to serious complications like the facial bone infection or the exacerbation of respiratory tract conditions, and the extension of infection to the brain and eyes.
There are different types of sinuses: frontal, maxillary, ethmoid, and sphenoid and the symptoms might differ when each one is affected; the symptoms also differ for acute and chronic sinusitis.
