Paranasal Sinus

http://ncicb.nci.nih.gov/xml/owl/EVS/Thesaurus.owl#C12763

One of many small hollow spaces in the bones around the nose. Paranasal sinuses are named after the bones that contain them: frontal (the lower forehead), maxillary (cheekbones), ethmoid (beside the upper nose), and sphenoid (behind the nose). The paranasal sinuses open into the nasal cavity (space inside the nose) and are lined with cells that make mucus to keep the nose from drying out during breathing.

Air-filled extensions of the respiratory part of the nasal cavity into the frontal, ethmoid, sphenoid, and maxillary cranial bones. They vary in size and form in different individuals and are lined by the ciliated mucous membranes of the nasal cavity.

An air-filled cavity adjacent to the nasal cavity lined by a mucous membrane and located in the bones of the skull. There are four paranasal sinuses on each side of the face: ethmoid, frontal, maxillary, and sphenoid sinus. (NCI)
