The sinuses are cavities within the skull. They drain into the nose through small holes. Sinusitis means inflammation of the nasal sinuses. Sinusitis is most commonly short-lived, such as after a viral cold. Blockage of the drainage pathways, however, creates an environment that favours the overgrowth of bacteria resulting in long-term (chronic) sinusitis. Hayfever and polyps are the most common reasons for having recurrent or chronic sinus infection.
