Sinusitis information from trusted sources:
Sinusitis means your sinuses are infected or inflamed. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain and infection. Sinusitis can be acute, lasting for less than four weeks, or chronic, lasting much longer. Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, pollutants, nasal problems and certain diseases can also cause sinusitis.
Sinusitis refers to inflammation of the sinuses that occurs with a viral, bacterial, or fungal infection. See also: Chronic sinusitis
Sinusitis is inflammation (swelling) of the lining of the sinuses, caused by a viral or bacterial infection.
Sinusitis is an inflammation of the paranasal sinuses. The paranasal sinuses are air-filled cavities in the facial bones that open into the nasal passage through tiny holes called ostia. Sinusitis occurs when the sinuses become inflamed and the ostia become blocked. In acute uncomplicated sinusitis, symptoms last less than one month, and may be treated by a generalist physician. Chronic sinusitis, defined as sinusitis of at least three months' duration, may require the care of an ear, nose, and throat (ENT) specialist. Most doctors believe that chronic sinusitis is a result of a series of past infections rather than a single persistent infection.
Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head. A person with a sinus infection may also have a cough, a fever, bad breath, and nasal congestion with thick nasal secretions. Sinusitis is categorized as acute (sudden onset) or chronic (long term, the most common type).
With chronic sinusitis, the cavities around nasal passages (sinuses) become inflamed and swollen. This interferes with drainage and causes mucus to build up. This common condition is also called chronic rhinosinusitis.
With acute sinusitis, the cavities around your nasal passages (sinuses) become inflamed and swollen. This interferes with drainage and causes mucus to build up. This common condition is also called acute rhinosinusitis.
