[Nasal irrigation in case of rhinosinusitis].

Nasal irrigation has proven in several recently published articles its clinical effectiveness and its neglectable rate of side effects even in children and during pregnancy. In most guidelines for the treatment of various nasal pathological conditions nasal irrigation is recommended as stand alone or as additional therapy. Although no common treatment protocol exists, a isotonic (0.9 %) or slightly hypertonic solution (3 - 5 %) is suggested because of its positive influence upon mucociliary clearance. Buffered solutions bring a more pleasant feeling during rinsing, which explains also the beneficial effect of natural brine solutions. In children, nasal irrigation can save antibiotics and reduce decongestant to nil. Important is the hygienic application in order not to introduce additional pathogenic germs into the nasal system.
