The air chambers in the bone behind your cheeks, eyebrows and jaw are called sinuses. They make mucus, a fluid that cleans bacteria and other particles out of the air you breathe. Tiny hairs called cilia (say: “sill-ee-ah”) sweep mucus out of your sinuses so it can drain out through your nose. Return to top What is sinusitis? Sinusitis (say: “sine-you-site-iss”) is the name for a condition in which the lining of your sinuses becomes inflamed. Return to top What causes sinusitis? Anything that causes swelling in your sinuses or keeps the cilia from moving mucus can cause sinusitis. This can occur because of changes in temperature or air pressure. Using decongestant nasal sprays too much, smoking, and swimming or diving can also increase your risk of getting sinusitis. Some people have growths called polyps (say: “pawl-ips”) that block their sinus passages. When sinusitis is caused by a bacterial or viral infection, you get a sinus infection. Sinus infections sometimes occurs after you’ve had a cold. The cold virus attacks the lining of your sinuses, causing them to swell and become narrow. Your body responds to the virus by producing more mucus, but it gets blocked in your swollen sinuses. This built-up mucus makes a good place for bacteria to grow. The bacteria can cause a sinus infection.

Later, when the medicines you've been taking to relieve the symptoms of the common cold are not working and you've now got a terrible headache, you finally drag yourself to the doctor. After listening to your history of symptoms, examining your face and forehead, and perhaps doing a sinus X-ray, the doctor says you have sinusitis. Sinusitis simply means inflammation of the sinuses, but this gives little indication of the misery and pain this condition can cause. Chronic sinusitis, sinusitis that persists for at least 3 weeks, affects an estimated 32 million people in the United States. Americans spend millions of dollars each year for medications that promise relief from their sinus symptoms. Sinuses are hollow air spaces, of which there are many in the human body. When people say, "I'm having a sinus attack," they usually are referring to symptoms in one or more of four pairs of cavities, or spaces, known as

It's usually caused by infection. Our sinuses are the moist air spaces within the bones of the face around the nose. The frontal sinuses are located in the area near the eyebrows; the maxillary sinuses are located inside the cheekbones; the ethmoid sinuses are between the eyes; and the sphenoid sinuses sit behind the ethmoid sinuses. When we're healthy, our sinuses are filled with air, making our facial bones less dense and much lighter in weight.

Sinusitis can affect the nose, eyes, or middle ear, and may be indicated by plentiful, thick, colored nasal drainage, bad-tasting post-nasal drip, cough, head congestion and an accompanying headache. Symptoms may also include a plugged-up nose, a feeling of facial swelling, toothache, constant tiredness, and occasionally, a fever.

Sinuses are a part of the upper respiratory system. Adults and older children have four groups of sinus cavities (maxillary, ethmoid, frontal, and sphenoid) located within the bones surrounding the nose. Very young children have small sinus passages and cavities rather than fully formed sinuses. Under normal daily conditions, the sinuses produce up to 1.5 liters of mucus per day! Allergy, infection, or environmental triggers may increase mucus production or change the characteristics of the mucus in the nose and cause symptoms. Each sinus cavity has an opening into the nose to allow for drainage of this mucus. Therefore, anything that causes swelling in the nose may lead to obstruction or blockage of the sinuses leading to infection and more sinus problems. To work properly, the sinuses need adequate mucus drainage and a functioning immune system to fight off infections and inflammation. What is sinusitis?

Sinusitis A lot of people mistake a particularly bad cold for sinusitis. Many of the symptoms are the same including headache or face pain, a nasty runny nose and nasal congestion. Unlike a cold, some cases of sinusitis are bacterial infections that often require antibiotics. While mild cases of sinusitis may go away without medical intervention, sinusitis also can be serious and can require surgery if left untreated. However, a bad cold won't respond at all to antibiotics. About 31 million people develop sinusitis in the United States each year. Frequently, sinusitis follows an upper respiratory infection or a normal cold. People who have allergies, asthma, physical abnormalities in the nose or sinuses, or a compromised immune system are at a greater risk. What is sinusitis? Sinusitis is an inflammation of the mucous membranes lining the facial sinuses. The inflammation is often caused by a bacterial infection, although viruses and fungi are also implicated. Immunocompromised people can develop bacterial or fungal sinusitis. Some allergic individuals, who are not immunocompromised, can have "allergic fungal sinusitis". Acute sinusitis lasts three to eight weeks. Sinusitis lasting more than eight weeks is considered chronic. The sinuses are air-filled cavities in the skull. Normally, they are lined with a thin layer of mucus that traps dust, germs and other airborne particles. Tiny hairs in the sinuses called cilia sweep the mucus (and whatever is trapped in it) towards openings in the top of the sinuses called ostia. The ostia lead to the back of the throat where mucous slides down to the stomach. This continual process is a normal function of the body.

Sinus symptoms are very common during a cold or flu, but in most of these cases they are due to the effects of the infecting virus and resolve when the infection does. It is important to differentiate between inflamed sinuses associated with cold or flu virus and sinusitis caused by bacteria. With true acute bacterial sinusitis, the signs and symptoms typically have the following course: Nasal congestion and discharge comes first and is typically thick with pus that is yellowish to yellow-green. Pain in the teeth is increased by bending over. Symptoms may vary, however, depending on the sinuses involved. Symptoms continue for 10 days or more after the start of a cold or flu. They worsen after 5 - 7 days, or they return after initial improvement in a cold (called double sickening).

FAGNAN, M.D., Oregon Health Sciences University, Portland, Oregon A patient information handout on caring for acute sinusitis, written by Elizabeth Smoots, M.D. , is provided on page 1805. S inusitis is a common ailment: 16 percent of the U.S. population reports a diagnosis of sinusitis annually, accounting for 16 million office visits. Public interest in sinusitis is exemplified by a 1997 Internet search using Alta Vista, which found 4,960 matches. Furthermore, sinusitis is a costly disorder: about $2 billion is spent annually on medications to treat nasal and sinus problems. The National Ambulatory Medical Care Survey (NAMCS) lists sinusitis as the fifth most common diagnosis for which an antibiotic is prescribed. Sinus Anatomy and Function The function of the paranasal sinuses is not clear, but theories include humidification and warming of inspired air, lightening of the skull, improvement of vocal resonance, absorption of shock to the face or skull, and secretion of mucus to assist with air filtration. The four paranasal sinuses (maxillary, frontal, ethmoid and sphenoid) develop as outpouchings of the nasal mucosa. They remain connected to the nasal cavity via narrow ostia with a lumen diameter of 1 to 3 mm (Figure 1) . The sinuses are lined with mucoperiosteum, which is thinner and less richly supplied with blood vessels and glands than the mucosa of the nasal cavity. Cilia sweep mucus toward the ostia. The ostia of the frontal, maxillary and anterior ethmoid sinuses open into the osteomeatal complex, which lies in the middle meatus lateral to the middle turbinate. The posterior ethmoid and sphenoid sinuses open into the superior meatus and sphenoethmoid recess. The osteomeatal complex is important because the frontal, ethmoid and maxillary sinuses drain through this area.

Sinusitis is categorized as acute (sudden onset) or chronic (long term, the most common type). Anatomy of the sinuses (also called paranasal sinuses): The human skull contains four major pairs of hollow air-filled–cavities called sinuses. These are connected to the space between the nostrils and the nasal passage . Sinuses help insulate the skull, reduce its weight, and allow the voice to resonate within it.
