Chronic Sinusitis


An acute sinus infection involves a blocked nose, limited sense of smell, headache and a sore face. Typical symptoms are a sense of pressure in the areas affected and mucus running down the back of the throat. Usually acute sinusitis resolves after about two to three weeks. If symptoms persist for longer than twelve consecutive weeks1, this is referred to as chronic sinusitis. Women are more often affected than men.2

Talk to your doctor


By explaining the symptoms in detail, your doctor will be able to provide a targeted treatment plan for your chronic sinusitis. They can also tell you what you can do to actively help. In the discussion, your doctor will try to identify the possible causes for the disease and rule out certain causes.

Possible causes


The most common causes of acute sinusitis are colds and flu. The development of a chronic sinusitis depends on various factors. It can be exacerbated by allergic rhinitis, for example. Dental problems may also contribute by allowing pathogens in the upper jaw to enter the nearby sinuses.3

Pre-existing conditions and impaired immune system


Existing respiratory diseases such as COPD, asthma and cystic fibrosis can encourage the development of chronic sinusitis. The same applies to impaired immune defenses, germs or nasal polyps. Medication intolerances are another possible cause. Individual anatomical differences can also encourage the development of chronic sinusitis: these include nasal polyps, large nasal conchae or a curved nasal septum. They have a chronic impact on the ventilation of the sinuses and the flow of mucus and may block drainage from the sinuses and cause a sinus infection.

Therapy Options

Regular nasal rinsing with isotonic salt solutions may help to ease symptoms. PARI offers a comprehensive range of medical devices and inhalation devices for the care and therapy of the upper airways.
