The mucus film, along with any particles of dirt that are breathed in are continuously transported towards the sinuses and throat by very fine hairs. This helps to keep this area free of dust and germs. Having a cold can cause inflammation of the mucous membrane. It suddenly produces much more mucus and swells the nasal passage. This can obstruct the fine connections between the nose and the sinuses. The mucus cannot drain as well or cannot drain at all, which causes it to build up and become the ideal breeding ground for germs that can trigger acute sinusitis.

Usually sinusitis resolves after a few weeks. There are a variety of factors that determine whether sinusitis, called rhinosinusitis, recurs or develops into a chronic disease. These include the body’s own defense system, predisposition to allergies or anatomical conditions: e.g. nasal polyps or a curved nasal septum.

PARI has been focused for decades on all diseases affecting the airways. Clinically-proven inhalation devices support aerosol delivery to the sinuses. Nebulization to the sinus cavities delivers the solutions or medication prescribed by your doctor directly to the sinuses, where they are needed.
