Clinical Relevance: Sinusitis. As the paranasal sinuses are continuous with the nasal cavity, an upper respiratory tract infection can spread to the sinuses. Infection of the sinuses causes inflammation (particularly pain and swelling) of the mucosa, and is known as sinusitis. If more than one sinus is affected, it is called pansinusitis.
Human sinuses are broken into four groups known collectively as the paranasal sinuses. These four groups are: maxillary, frontal, sphenoid and ethmoids. All four are located in the bones of our skulls, but they are also attached to the nose. When one of them becomes infected it can affect more than just the nasal passages. It can cause pain and swelling in the eyes, face, or jaw. For example, the maxillary sinuses; which are located beneath the eyes and also in the facial cheekbones on the side of the nose, can cause jaw pain when they become infected.
