• Acute sinusitis (sinus infection): Viruses or bacteria infect the sinus cavity, causing inflammation. Increased mucus production, nasal congestion, discomfort in the cheeks, forehead or around the eyes and headaches are common symptoms.
• Chronic sinusitis (or chronic rhinosinusitis): More than just a series of infections, chronic sinusitis is a persistent process of inflammation of the sinuses.
• Allergic rhinitis: Allergens like pollen, dust mites, or pet dander cause the defenses in the nose and sinuses to overreact. Mucus, nasal stuffiness, sneezing, and itching result.
• Deviated septum: If the septum that divides the nose deviates too far too one side, airflow can be obstructed.
• Turbinate hypertophy: The ridges on the nasal septum are enlarged, potentially obstructing airflow.
• Nasal polyps: Small growths called polyps sometimes grow in the nasal cavity, in response to inflammation. Asthma, chronic sinus infections, and allergic rhinitis can lead to nasal polyps.

Sinus Tests

• Physical examination: A doctor can look into the nose with a lighted viewer to see the turbinates, which may be swollen. She may press or tap on the face over the sinuses to check for pain.
• Computed tomography (CT scan): A CT scanner uses X-rays and a computer to create detailed images of the sinuses. CT scanning can help diagnose chronic sinusitis.
• Magnetic resonance imaging (MRI): Magnetic waves create highly detailed images of the sinuses. CT and MRI scans may be used together.
• Endoscopy (rhinoscopy): Using a flexible tube with a camera on its end, a doctor can examine the inside of the nose and sinuses.
• Sinus cultures: A mucus sample can be taken from inside the sinuses. This is done with a needle or during endoscopy.
• Skin Test for Allergies: Skin testing for various allergens can help determine if allergies are contributing to sinusitis.
• Sinus X-ray: A plain X-ray may show problems with the bones around the sinuses. A CT scan is superior to plain X-ray films.

First line of defense against sinusitis: Nasal irrigation

One of the simplest, cheapest, and most effective ways to prevent and treat sinus problems is nasal irrigation. Using a homemade solution, you can often relieve sinusitis symptoms, reduce reliance on nasal sprays and antibiotics, and improve your quality of life. At least once a day, follow these steps:

1. Stir ½ teaspoon of non-iodized salt and ½ teaspoon of baking soda into 2 cups of lukewarm distilled or previously boiled water (as recommended by the American Academy of Otolaryngology).
2. Fill a small bulb syringe with the saltwater solution. (If you prefer, you can use a small pitcher called a neti pot to stream the solution through your nose.)
3. Lean over your bathroom or kitchen sink, insert the tip of the syringe just inside one nostril, and gently squeeze the bulb. The water will run back out the nostril (or possibly the opposite nostril) and into the sink. Use at least one full bulb of solution.
4. Repeat the procedure in the other nostril. (If the salt solution stings your nose, use less salt.)
5. Thoroughly rinse (with distilled or cooled boiled water) and dry the bulb syringe or neti pot after each use.

OTHER TREATMENTS:

• Along with Nasal saline spray: Salt water nasal spray breaks up dried mucus and helps to keep the nose moist or
• Nasal washes: rinse mucous from the nasal cavities and sinuses here are other treatments.

• Decongestants: Medications that cause blood vessels in the inner nasal tissue to constrict. As a result, there is less sinus congestion, mucus production and postnasal drip.
• Nasal steroid spray: Regular use of nasal steroids can reduce the symptoms of allergic rhinitis. These medications help relieve tissue swelling and help prevent the regrowth of nasal polyps after sinus surgery.
• Antibiotics: Anti-bacterial oral medicines may be needed to treat bacterial sinusitis.
• Sinus surgery: Surgery can improve or correct some sinus conditions. Usually surgery is used to remove growths or to open an obstruction.
