Sinusitis is an acute or chronic inflammation of the sinuses.



The sinuses are cavities located in the skull. There are four pairs of sinuses surrounding the nose and eyes that connect to the nasal cavity through small openings. The sinuses produce mucus which cleans the nose. Sinusitis is an inflammation of the sinuses and is generally caused by an infection such as a cold or the flu that congests and blocks the opening between the sinuses and the nasal cavity. The mucus, trapped, congests the sinuses. This creates a highly conducive environment where viruses and bacteria can thrive and proliferate, leading to sinusitis. One person in 10 suffers from sinusitis each year. Sinusitis does not discriminate, it affects adults and children alike.
