Illustration of the ciliated cells of the sinus. These cells drain mucus that traps external particles. In the case of sinusitis, the ciliated cells don't play their irrigation role as efficiently, allowing external particles to proliferate, causing congestion of the mucous membrane, as well as swelling and obstruction of the sinuses.
