Clinical Question:
Is nasal saline irrigation (NSI) helpful for rhinosinusitis?

Nasal saline irrigation does not improve acute rhinosinusitis (example “colds”). It can improve allergic and chronic rhinosinusitis^ improving symptoms -30 percent and improving quality of life with rhinosinusitis at least 10 percent for one in two patients. Isotonic is as good as hypertonic and rinses are better than sprays (but with more adverse events).
