Sinusitis

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of sinusitis.

Alternative Names

Nasal congestion; Rhinosinusitis

Treatment for Chronic Sinusitis

Determining and Treating any Underlying Conditions. A thorough diagnostic work-up should be performed to rule out any underlying conditions, including but not limited to allergies, asthma, any immune problems, gastroesophageal reflux disorder, and structural problems in the nasal passages. If a primary trigger for chronic sinusitis can be identified, it should be treated or controlled if possible.

Initial Treatment of Sinusitis. For treatment of chronic sinusitis itself, some doctors recommend:

• A wide spectrum antibiotic (one that can eliminate a wide range of bacteria) taken for at least 30 days
• Alternatively, an antibiotic that attacks anaerobic pathogens
• A corticosteroid nasal spray --some doctors also recommend oral corticosteroids (such as prednisone) for patients who do not respond to nasal corticosteroids or for those patients who have nasal polyps. Prednisone is also used for patients who have allergic fungal sinusitis.
• Saline nasal washes
• The expectorant guaifenesin with a decongestant taken by mouth
• Antihistamines

If the condition dramatically improves between 1 - 2 months, then the antibiotics are stopped. The patient should continue with both the steroid and saline nasal solutions. If there is no improvement after this time, the surgery may be considered. For some people with chronic sinusitis, however, the condition is not curable, and the goal of treatment is to improve the quality of life.

Antibiotics for Chronic Sinusitis

Chronic sinusitis is often the result of damage to the mucous membrane from a past, untreated acute sinus infection. The aerobic and anaerobic bacteria present in chronic sinusitis are often different from those that cause the acute form. The role of antibiotic treatment for chronic sinusitis is controversial. Special types of antibiotics may be used, and treatment may be needed for a longer time.

Intravenous antibiotic therapy may be required for some patients with chronic sinusitis, particularly those with underlying medical disorders that can worsen the condition. They are typically administered 2 weeks before surgery and continued for about month afterward.

Some studies have reported good results in using antibiotics that are sprayed into the nasal passages using a nebulizer. In one study, patients preferred this method to either oral or intravenous treatments.

Corticosteroids for Chronic Sinusitis

Benefits of Corticosteroid Nasal Sprays. Nasal-spray corticosteroids, most commonly called steroids, are effective drugs for treating allergic rhinitis. They also are proving to be very important in the treatment of chronic sinusitis and are sometimes used for acute sinusitis. Some studies have reported that, when combined with antibiotics, they speed recovery and improve healing rates of sinusitis compared to antibiotics alone. Nasal spray steroids are proving to be safe and have the following benefits:

• They reduce inflammation and mucus production
• They improve night sleep and daytime alertness in patients with perennial allergic rhinitis
• They appear to be beneficial in treating polyps in the nasal passages

Nasal-Spray Brands. Corticosteroids available in nasal spray form include:

• Triamcinolone (Nasacort). Approved for children over age 6.
• Mometasone furoate (Nasonex). Approved for use in patients as young as age 3.
• Fluticasone (Flonase, Flounce). Approved for children over age 4.
• Beclomethasone (Beconase, Vancenase), flunisolide (Nasalide), and budesonide (Rhinocort). Approved for children over age 6.

Side Effects. Corticosteroids are powerful anti-inflammatory drugs. Although oral steroids can have many side effects, the nasal-spray form affects only local areas, and the risk for wide spread side effects is very low unless the drug is used excessively.

• Dryness, burning, stinging in the nasal passage
• Sneezing
• Headaches and nosebleed (these side effects are uncommon but should be reported to your doctor immediately)

Possible Long-Term Complications. Corticosteroids suppress stress hormones, which are known to produce some serious long-term complications in people who take oral steroids. Researchers have found far fewer concerns with nasal administration or inhaled forms, but there may be certain problems.

• Effect on growth. The major concern for children is whether nasal steroids, like other forms of steroids, will adversely affect growth. Studies report either only a temporary and slight (about half an inch) early effect on growth or no effect at all.
• Effect on eyes. Glaucoma is a known side effect of oral steroids. Some ophthalmologists have observed higher pressure in the eye (a sign of glaucoma) in some patients taking nasal steroid sprays. Studies have found no increased risk for cataracts in young people who have taken intranasal steroids. All the conditions resolve after stopping the steroid, although periodic eye examinations are advised.
• Use during pregnancy. Steroids are most likely safe during pregnancy, but pregnant women should discuss all options carefully before taking them.
• Nasal passage injury. Steroid sprays may injure the nasal septum (the bony area that separates the nasal passage) if the spray is directed onto it. This complication is very rare.
• Lower resistance to infection. People with any infectious disease or injury in the nose should not take these drugs until the disease or wound has been treated and cured. People should avoid steroids if they have not been vaccinated or have had chicken pox or measles.
• In some cases, people become insensitive to the effects of corticosteroids and they stop working.

Leukotriene-Antagonists

Leukotriene-antagonists are oral drugs that block leukotrienes, powerful immune system factors that are important in causing airway constriction and mucus production in allergy-related asthma. Leukotriene-antagonists include zafirlukast (Accolate), montelukast (Singulair), (Ziflo), and pranlukast (Ultair, Onon). They may also be useful in certain cases of chronic sinusitis, including sinusitis due to polyps, when allergies are the cause, or in some cases when the cause is unknown.

Antifungals

Scientists are investigating whether antifungal drugs may help treat chronic sinusitis. One such drug, Amphotericin B (SinuNase), is currently in Phase III trials for patients who have had sinus surgery but are still experiencing recurrent sinusitis. Results from previous clinical trials have been mixed.

Managing Sinusitis in Patients with Allergies, Asthma or Both Patients often have various combinations of allergies, sinusitis, and asthma. Treating each condition is important for improving them all. In addition to decongestants, pain relievers, and expectorants, other remedies are available for people who suffer from nonbacterial sinusitis during allergy season. Anti-Inflammatory Drugs. Nasal spray corticosteroids (commonly called steroids) are important for reducing the inflammatory response in the nasal passages and airways. They are important in the treatment of asthma and are now considered to be the most effective measure for preventing allergy attacks. Leukotriene-antagonists are also useful for sinusitis symptoms. Antihistamines. Antihistamine tablets relieve sneezing and itching and can prevent nasal congestion before an allergy attack. Many brands are available by prescription and over the counter. Immunotherapy. Immunotherapy, commonly referred to as "allergy shots", may be considered for patients with severe seasonal allergies that do not respond to treatment. Immunotherapy is the only treatment that affects the cause of allergies. In one year-long study using immunotherapy, over half of young patients participating experienced improvement in overall sinusitis symptoms, and nearly all felt better in general. Immunotherapy also may prevent asthma and the development of new allergies in children. Newer immunotherapeutic approaches using specially designed antibodies and vaccines are also showing promise. All drug treatments have side effects, some very unpleasant and, in rare cases, serious. Patients may need to try different drugs until they find one that relieves symptoms without producing excessively distressing side effects.
