The purpose of cilia in the sinus cavities is to sweep mucous out of the cavities.
Mucous in turn is produced in order to protect the human body from pollutants we breathed in daily.
Cilia are also found in the lungs; trachea and throat.
Contamination from pollutants; is lodged to the mucous and this mucous is expelled by the cilia.
Within the facial bones and surrounding the nose area are the sinus cavities which are literally moist air spaces.
When mucous collects in these sinus cavities due to inhaling external pollutants; they will drain into the nasal passage; and should these cavities become inflamed they are unable to drain normally.
You will become congested and infection will set in.
Once there is an infection in the cavities it will cause considerable swelling in the sinus passages and will prevent the cilia from moving the built up mucous and hence will cause sinusitis.
This mucous which now cannot be expelled through the nose will drip down the back of the throat - post nasal drip - and into the lungs causing an infection.
If you are a smoker you are at far more risk contracting infections of the sinus cavities; as it has been proved that smoking causes the cilia to perform at a very low peak.
This make it almost impossible for the body to clear the mucous out and you end up with severe coughs and other lung diseases.
The cilia when looked at under a microscope have tail like projections which extend themselves from a cell body.
A number of human diseases will develop when the cilia are malfunctioning; as well as infections going into the brain; causing severe illnesses.
If your immune system is down; chances are that your cilia are not functioning correctly; as the cilia are weak and are unable to clear all the debris from the sinus cavities while normal functioning cilia would clear the irritating matter out.
With this congestion you probably will experience bad breath as well.
The medical fraternity state that if the cilia are functioning properly; patients would not experience sinus attacks.
So when you have a sinus attack you will be aware of what is taking place inside the sinus cavity and avoid taking any medication that would harm the cilia.
Keep your cilia healthy and the cilia will keep you healthy.
