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 and located in the body of the maxilla (upper jaw). It is the sinus that is the most likely to become infected and given its size and close proximity to other key structures on the skull, there is a risk of the infection spreading.
