The sinuses are cavities in the bones around the eye sockets. They are lined with the same tissue as in the nose and all of them communicate into the nasal cavity.
The frontal sinus is in the bones of the forehead, just above the eye. The maxillary sinus, often called the antrum, is in the cheekbone just below the eye.
On either side of, and behind the bridge of the nose, are the ethmoidal and sphenoidal sinuses in small bones which form the nasal side of the eye sockets.
Many people come to the doctor and complain: “It’s my sinus.”
I’m never sure what they really mean by this, whether their symptoms refer to headache, a blocked or running nose, or something else.
Acute infection in the sinus is not uncommon. The maxillary sinus is the one usually affected. Infection may spread upwards from the nose, usually during the course of a cold.
The lining of the sinus becomes swollen and sometimes blocks the small opening leading into the nose. This causes collection of pus and mucus under pressure and it is responsible for the severe pain.
