Paranasal sinus

Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity.

The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes.

The sinuses are named for the facial bones in which they are located.
