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 and sphenoid bone in which they are located. Their role is disputed.
'sieve') is an unpaired bone in the skull that separates the nasal cavity from the brain. It is located at the roof of the nose, between the two orbits. The cubical bone is lightweight due to a spongy construction. The ethmoid bone is one of the bones that make up the orbit of the eye.
The four paired sinuses or air cavities can be referred to as: Ethmoid sinus cavities which are located between the eyes. Frontal sinus cavities which can be found above the eyes (more in the forehead region). Maxillary sinus cavities are located on either side of the nostrils (cheekbone areas). Sphenoid sinuses that are located behind the eyes ...
Frontal sinuses are rarely symmetrical as the septum between them frequently deviates to either side of the midline. [3] [1] The two sinuses also vary in extent compared to one another. [2] Their size of the frontal sinuses is highly variable. [2] Rarely, one or both sinuses is hypoplastic [1] or even absent. [1] [2]
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
The sphenoid sinus is a paired paranasal sinus in the body of the sphenoid bone. It is one pair of the four paired paranasal sinuses. [1] The two sphenoid sinuses are separated from each other by a septum. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus.

The confluence of sinuses shows significant variation. [1] Most commonly, there is a continuous connection between all of the sinuses. [1] [2] A very common variant is the superior sagittal sinus only draining into the right transverse sinus - more rarely, it may also only drain into the left transverse sinus.
