This condition can result from infections, allergic reactions, anatomical defects of the sinuses and pathologies of the teeth of the upper arch.

Maxillary sinusitis typically causes pain in the cheek region, nasal congestion, purulent rhinorrhea, toothache, and frontal headache. Sometimes, general malaise and fever are also associated.

The diagnosis of maxillary sinusitis is made on the basis of clinical evaluation, endoscopic examination of the middle meatus and computed tomography (CT) of the facial massif.

Decongestants, corticosteroid nasal sprays, and moist heat applications can help relieve symptoms. The treatment of bacterial maxillary sinusitis is based, on the other hand, on antibiotic therapy. Surgery is indicated in case of failure of medical therapy and serves to correct the pathological causes and improve sinus drainage.

, acute or chronic, affecting one or more paranasal sinuses (frontal, maxillary, ethmoid and sphenoid).

The sinuses are cavities inserted into the thickness of the cranial bones, located behind the nose, between and above the eyes (at the level of the forehead and root of the nose) and behind the cheekbones. These structures communicate with the nose through the ostia (small ducts that allow mucus produced by the mucous membrane that lines the sinuses to pass through the nose).

Generally, the paranasal sinus most affected by sinusitis is the maxillary one.

The maxillary sinus is located between the nasal cavity and the oral cavity. For this reason, this area is susceptible to bacterial contamination both by germs from the oral cavity and by the agents that infect the upper airways.
