N: 1. “inflammation of the sinuses,” 1896; from “sinus” (“hollow curve or cavity in the body,” early 15c., from Medieval Latin sinus, from Latin sinus “bend, fold, curve, a bent surface; a bay, bight, gulf; a fold in land;” also “fold of the toga about the breast,” hence “bosom,” and figuratively “love, affection, intimacy; interior, inmost part;” of unknown origin) and “-itis” (word-forming element in medicine denoting “diseases characterized by inflammation” -of the specified part-, Modern Latin, from Greek -itis, feminine of adjectival suffix -ites “pertaining to”; Feminine because it was used with an implied nosos “disease,” a feminine noun; especially in arthritis (nosos) “(disease) of the joints”) “inflammation.”
2. Inflammation of a nasal sinus.
3. Inflammation of the lining membrane in any of the hollow areas (sinuses) of the skull around the nose. Sinusitis may be caused by anything that interferes with air flow into the sinuses and the drainage of mucous out of the sinuses. The sinus openings, called ostia, may be obstructed by swelling of the tissue lining the ostia and adjacent nasal passage tissue; for example, from colds, allergies, and tissue irritants (nasal sprays, cocaine, cigarette smoke). Less commonly, sinuses can become obstructed by tumors or growths. Stagnated mucous then provides a perfect environment for bacterial infection. The common symptoms of sinusitis include headache; facial tenderness or pain; fever; cloudy, discolored nasal drainage; a feeling of nasal stuffiness; sore throat; and cough. Acute sinusitis is usually treated with antibiotic therapy. Chronic forms of sinusitis require long courses of antibiotics and may require a sinus drainage procedure.
4. There are several types of sinusitis:

• Acute sinusitis (acute rhinosinusitis) causes the cavities around your nasal passages (sinuses) to become inflamed and swollen. This interferes with drainage and causes mucus to build up.
• With acute sinusitis, it might be difficult to breathe through your nose. The area around your eyes and face might feel swollen, and you might have throbbing facial pain or a headache. Acute sinusitis is mostly caused by the common cold. Unless a bacterial infection develops, most cases resolve within a week to 10 days.
• Chronic sinusitis (chronic rhinosinusitis) is a common condition in which the cavities around nasal passages (sinuses) become inflamed and swollen for at least 12 weeks, despite treatment attempts.
