Each time you have a cold or an allergic attack the mucosal surfaces of the nose and the adjacent sinuses swell up. Sinus openings are clogged as a result. Due to the ostium (opening) swelling up, discharge of mucus may not occur normally/naturally. We call this inflammation of the sinuses ‘sinusitis’.
The picture on the left shows a healthy sinus. The opening of the chamber that leads to the nasal passage is clear and the walls of the nasal membranes are lined with a thin layer of mucus on the surfaces.
In the picture on the right, the mouth of the chamber is swollen and clogged with mucus. Likewise the sinus walls lining is over swollen and full of mucus. (Sinusitis).
