Chronic sinusitis

Chronic sinusitis: Introduction

Chronic sinusitis is a long-term ongoing or recurring inflammation of the air-filled spaces that are located within the bones in and around the nose. These spaces are called paranasal sinuses, and when they get infected, they become inflamed. This results in swelling of the mucus membranes that line the sinuses, which causes pain and pressure in and around the eyes and cheekbones.

Chronic sinusitis differs from acute sinusitis in that chronic sinusitis occurs for more than a couple of months or continues to recur while acute sinusitis is short-lived and does not recur. Both chronic sinusitis and acute sinusitis can result from a viral infection, bacterial infection, or rarely, a fungal infection of the sinuses. Risk factors for the development of chronic sinusitis include having nasal polyps, nasal tumors, deviated nasal septum, asthma, and allergies.

An infection occurs when the body's immune system is unable to stop the multiplying of harmful bacteria, viruses or fungi that have been introduced into the sinuses. This results in the inflammation of the sinuses and symptoms, such as facial pain and pressure and thick greenish mucus that is discharged from the nose. Severe complications that affect the brain may also occur. For more details on symptoms and complications, refer to symptoms of chronic sinusitis.

Making a diagnosis of chronic sinusitis begins with taking a thorough medical history, including symptoms, and a physical examination that focuses on the nose and sinuses. Findings include swelling and inflammation of the sinuses and thick greenish nasal mucus. Diagnostic testing may include imaging tests, such as an X-ray or CT, which can confirm a diagnosis and reveal the severity of the condition. A nasal endoscopy may be performed to look at the inside of the nose and sinuses.

If chronic sinusitis is suspected to be caused by allergies, a referral is made to a specialist called an allergist for further diagnosis and treatment of the underlying allergy. It is possible that a diagnosis of chronic sinusitis can be missed or delayed because the symptoms can be mild or be similar to symptoms of conditions and diseases, such as migraine headache or upper respiratory infection. For more information on diseases and conditions that can mimic sinusitis, refer to misdiagnosis of chronic sinusitis.

Treatment of sinusitis varies depending on the cause, severity of symptoms, the presence of complications, a person's medical history. Treatment may include medications and possibly surgery in some cases. For more information on treatment, refer to treatment of chronic sinusitis....more »
