What Does Ethmoid Sinus Mean?
The ethmoid sinuses are a pair of air pockets located along the ethmoid bone and between the eyes. Within the bone structure of the skull, there are several open cavities referred to as the sinuses. The large, frontal sinuses are located at the center of the face above the eye sockets. Below the eyes on either side of the nose are the maxillary sinuses. Between the eyes on either side of the bone that forms the bridge of the nose are the smaller ethmoid and sphenoid sinuses. These cavities are collectively referred to as the paranasal sinuses.
The ethmoid sinuses are also called ethmoidal air cells.
