paranasal sinus, any one of the air cavities in various bones around the nose, such as the frontal sinus in the frontal bone lying deep to the medial part of the superciliary ridge and the maxillary sinus within the maxilla between the orbit, the nasal cavity, and the upper teeth. See also accessory nasal sinuses.
These are called the paranasal sinuses. They lighten the skull and give resonance to the voice. The paranasal sinuses have the same kind of tissue that lines the inside of the nose. The same things that can cause swelling in the nose, allergies or infection, can also affect the sinuses. When the tissue inside the sinuses swells, mucus increases. Over time, air trapped inside swollen sinuses can create painful pressure inside the head. This is a sinus headache.
