Chronic sinusitis, on the other hand, is most likely a result of an airborne allergy to substances like mold, dust and pollen that cause chronic allergic rhinitis nasal inflammation.

The treatment for sinusitis is best determined by its likely cause.

But research is now expanding to examine the role of genetic and immune-system players in the condition, as well as the possible contribution of our microbiome, the host of bacteria and viruses that live in and on our bodies. A number of new biological therapies now being tested in clinical trials have the potential to give physicians the first new treatment options in decades.

    Put simply, chronic sinusitis develops from perpetually inflamed sinuses.

    A number of inflammatory agents, from bacteria to fungi, find their way up the nose and into the membranous pockets embedded within our skulls.

      Beneath the pink sinus tissue are submucosal glands, which resemble clustered grapes and produce two types of secretions: serous and mucus. Serous refers to the watery snot that dribbles from eyes and nostrils on a cold morning; mucus is composed of sticky, glue-like proteins called mucin. Working with microscopic hairs called cilia, mucus helps block harmful substances from passing into the tissue and damaging our bodies. When an irritant makes its way into the nasal passage, be it pollen or particulate matter, mucus engulfs it and cilia oscillate in unison to carry the contents back out of the nose or into the throat for digestion.
