What Are Nasal Sinuses And Sinusitis

The nasal sinuses are extensions of the nasal cavity, normally filled with air. A man has eight or more of these small cavities in the bones of the forehead and cheeks. The largest sinuses are located in the maxillary bone, a slightly smaller are located in the upper part and on the side of the nasal cavity.

All of these cavities are lined with mucous membranes of the nasal cavity, and the mucus, which is located in the sinuses enters the nose. There are many opinions as to why we have sinuses. It is possible that they contribute to warming the air that passes through the nose and maintain its moisture. Or, perhaps, allow more ringing (reasoning) to vote. Maybe sinuses, normally filled with air, there are just to the skull was as light as possible.

Sinusitis can occur after severe fever or flu or any other infectious disease. During sinusitis pain is felt on the face, forehead or near the eyes, which usually occurs every day at the same time. Sometimes there is a greater secretion of mucus from the nose. The pain is caused by pressure of the mucus that collects in the sinuses, due to inflammation of the mucous membranes, can not normally be poured into the nose.

Sinusitis in the upper-jaw bones can sometimes be due to diseases of the upper teeth. Sinusitis rarely require surgery. And when it comes to operations, its goal is to expand the hole in the nose to allow more outflow of mucus.

Sinusitis can be divided by the duration of the disease: acute, subacute and chronic. Acute sinusitis is every one that lasts less than 4 weeks, subacute duration is 4-12 weeks and chronic lasts from 12 weeks onwards. All three diseases have the same symptoms, and differ only in duration.

Acute sinusitis usually occurs as a result of viral colds, which leads to inflammation and damage to the lining of the sinuses, which can then begin to multiply bacteria that are present. Chronic sinusitis usually develops as a consequence of asthma, allergies to a variety of causes from the environment, non-allergic vasomotor inflammation of the nose, obstruction of the nose and sinus openings because of distorted nasal septum or nasal polyps and facial trauma with fracture of bones.

If you get a sinus infection, several measures can help to ease the symptoms:
– Inhalation the nose – inhaling with the fumes of chamomile or bathing in hot water and inhaling the hot, humid air.
– Use of warm compresses – wet, warm towel over the nose, cheeks and eyes will help reduce the pain.
– Large fluid intake – a lot of fluid allows the dilution of thick mucus in the nose and sinuses and facilitates its ejection.
