Sinusitis is inflammation of which anatomical region?

Explanation:
Sinusitis denotes inflammation of the sinuses—the air-filled cavities around the nasal passages in the skull (the maxillary, frontal, ethmoid, and sphenoid sinuses). The term “itis” signals inflammation, so when the sinuses become irritated or infected, they swell and the drainage pathways into the nose can become blocked. This leads to symptoms like facial pressure or pain, congestion, and nasal discharge. The other areas listed (lungs, heart, kidneys) are not the sites named by this condition, since inflammation of those organs has different names (for example, inflammation of the lungs or airways is not sinusitis).
