Maxillary Sinuses

The maxillary sinuses are chambers or cavities located in the maxilla or upper jawbone, just below the eyes. They are connected to the nasal cavity and aid in air exchange, humidifying and warming the inspired air. The mucus in the sinuses also helps trap foreign particles that may enter the nose. Maxillary sinuses are particularly important as they help provide facial symmetry when present of both sides. In addition, sinusitis, or inflammation of the maxillary sinuses, can be caused by infection or allergies and can lead to a range of symptoms including facial pain, headache, nasal congestion, and discolored nasal drainage. Treatment for sinusitis may include antibiotics, nasal sprays, or even surgery depending on the severity of the condition.
