Sinusitis comes from the Latin word ‘sinuo’ which means “to bend, wind, curve”, and in Greek its meaning “is to pertain”. In medical English, the suffix means an “inflammation”. According to Med lexicon’s medical dictionary, sinusitis is the “Inflammation of the mucous membrane of any sinus, especially the Para nasal.

Behind the bones of your face there are some hollow spaces, filled with air, which lead to the nose cavity – they are what we know as the sinuses. Your sinuses have the same mucous membrane lining as your nose does. The membrane produces a slimy secretion (mucus), keeping the nasal passages moist. The mucus traps dirt particles and germs.

Alternatively, Sinuses are cavities in the bone around the nose, the cheeks and the eyes. These cavities are lined with membranes that produce mucus and when the sinuses are functioning normally, this mucus serves a protective purpose-it warms and moistens incoming air and filters it for germs. When sinuses can’t drain properly, however, the mucus accumulates and becomes stagnant, making the area ripe for infection.
