Sinusitis is a condition which describes inflammation of the lining of the sinus passages caused by bacteria. Your sinuses refers to the air chambers in the bone behind your eyebrows, cheeks and jaw. Normally, mucous cleans the bacteria and other particles that collects in the sinuses. With the help of tiny hairs called cilia, mucous is moved out of sinuses so that it can drain into the nasal passages. However, when you have a cold or allergy attack, your sinuses become inflamed or infected and drainage cannot occur.
There are two types of sinusitis – acute bacterial sinusitis and chronic sinusitis. Acute bacterial sinusitis is an infection of the sinuses caused by bacteria and usually starts with a cold, allergy attack or as a result of environmental irritants. Chronic sinusitis is characterized by frequent bouts of sinusitis which lasts for three months or more.
More than 30 million people in the United States experience sinusitis each year. It affects all age groups, although certain groups are more prone to the condition. These groups include people who suffer from allergies, asthma, have a weak immune system, nose injury, are born with narrow nasal openings or smoke.
If left untreated, sinusitis can become serious and lead to eye infections or meningitis This spread of infection is very rare, as there are a number treatment options available to manage and control sinusitis. |
