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.
The maxillary sinuses are the largest of the paranasal sinuses. These are located within the areas of the upper jaws, below the eye sockets and behind the cheekbone. The drainage of the mucus from the maxillary sinus is through an opening called the ostium. Any obstruction to the mucus flow from the maxillary sinuses may cause a sinus infection. Amongst the other sinuses, maxillary sinus infection is most common.
