Nose and Paranasal Sinuses

Locations of the paranasal sinuses

Locations of the paranasal sinuses

The paranasal sinuses are four airspaces around the nasal cavity.

This is a diagram of the locations of the four paranasal sinuses. They are named according to the bones within which the sinuses lie: surrounding the nasal cavity (maxillary sinuses), above the eyes (frontal sinuses), between the eyes (ethmoid sinuses), and behind the ethmoid bone (sphenoid sinuses).
