Let's clarify what happens during a nasal irrigation cycle to the four pairs of sinuses – frontal, sphenoid, ethmoid, and maxillary; and to the nasal turbinates, the structures that expand and contract throughout the day creating periods of increased and decreased nasal congestion. 

As you may know, the primary way that nasal irrigation works is by mechanically flushing, cleansing, and moisturizing the nasal cavity with saline.  This removes irritants such as allergens, micro-organisms, environmental pollutants, and dried mucus, and it helps keep the turbinates from drying out, expanding, and causing congestion as a result.

With respect to the sinuses, nasal irrigation’s key benefit is to keep the tiny channels (ostia) that connect the sinuses to the nasal cavity open and unblocked, thus allowing the sinuses to drain properly into the nasal cavity.  The nasal turbinates sit near these ostia, and if they become swollen from allergens, pollutants, or dryness, the turbinates can block the ostia, thus contributing to sinus disease. Nasal rinsing removes irritants around the turbinates and keeps them moisturized, and as a result, they become less swollen, which both relieves congestion and helps keep the ostia unblocked and open. This is essential to good nasal health because it: 
1. Helps the sinuses maintain their natural drainage process.  The sinuses are lined with mucosa (also called the mucous membrane) which secrete mucus. This mucus is transported through the sinuses and nose by cilia, microscopic hairs that grow on the mucosal surface and move and push the mucus along. A healthy nasal-sinus system is one in which the mucus created in the sinuses can drain into the nasal cavity from which it ultimately travels into the stomach. This regular cycle of continuous mucus creation and drainage is essential to maintaining healthy cilia. Furthermore, mucus traps the various noxious materials that can cause sinus infections. Therefore, healthy cilia, proper drainage, and healthy nose and sinus membranes are essential to good nasal health.  

2.  Helps prevent the sinuses from becoming blocked and thus vulnerable to infection.  When the sinus cavities are blocked and cannot drain properly, they can become sealed and isolated – efficient incubators in which viruses and bacteria can colonize and thrive.  The blockage creates perfect conditions for the growth of microorganisms that cause infections.  
Please note: Medical studies show no clinical evidence that saline from nasal irrigation devices of any type consistently enters and rinses inside the sinus cavities.

But the important point is that it doesn’t matter. 
What matters for maintaining good sinus health is that the tiny drain channels connecting the sinuses to the nasal cavity remain open – so the mucus that the sinuses are constantly manufacturing can drain into the nasal cavity and do its job of trapping and evacuating what should not be there. The good news is that there is significant clinical evidence that the tiny openings (ostia) connecting the sinuses to the nasal cavity are rinsed clean by nasal irrigation – and this is one of nasal irrigation’s greatest benefits. 
Howard Levine, MD, a distinguished nasal sinus physician and RhinoSystem's Medical Director, believes that due to Naväge using suction, and to the saline being pulled rather than pushed, the areas in the nose and adjacent to the ostia are more effectively cleansed and mucus is more effectively drawn out of the sinuses as the saline rushes past their openings into the nasal cavity. This would be an improvement over devices that use positive pressure to push the rinse through the past the entrances, as do, for example, the neti pot and squeeze bottle.  In fact, Dr. Levine believes it is possible that positive pressure devices could actually force material into the sinuses. 

As you can understand from the above explanation, the key benefit of nasal irrigation as a preventive practice is to significantly improve and enhance the body's ability to maintain its own sinus cleansing and drainage system – naturally, without drugs. This becomes especially important for individuals with smaller than average channel openings, because it is easier for those smaller openings to become blocked preventing the sinuses from draining.  As a result, improved nasal health is directly related to removing stagnant irritants in the nose and around the sinus drainage channels.  The regular use of nasal irrigation mechanically removes those irritants, in the same way that improved oral health is directly related to the regular brushing and flossing that removes particles from the teeth and gums.
