Xylitol Nasal Flushes Helps Prevent Chronic Sinusitis

Over the years, there has been much about how beneficial a safe food additive called xylitolis in preventing infections. This naturally-occurring plant-based sugar substitute apparently has all sorts of anti-bacterial as well as anti-fungal properties. Given these properties, daily xylitol gum chewingor xylitol nasal sprayuse has been shown to help prevent recurrent acute ear infections and sinus infections... safe for use even in infants.

How may this occur? Toronto researchers figured out that xylitol inhibits the adherence of germs (burkholderia in the study) to airway linings thereby helping to prevent recurrent infections.

Another beneficial practice found to be helpful in preventing sinus infections are saline flushes to the nose. For those who don't realize the difference, saline flushes are different from saline nasal sprays in the volume of irrigation performed (think garden hose versus squirt bottle). Nasopurenasal flushes is being shown in the picture above (there are many different stylesbut all basically do the same thing).

Now what if we combine saline flushes with xylitol for those who suffer from particularly difficult chronic sinus infections???

Stanford University researchers conducted a small study (20 subjects) to see whether xylitol flushes (rather than nasal spray) to nose works even better than plain saline flushes to the nose. In spite of its small size, it was a prospective, randomized, double-blinded, controlled crossover pilot study.

What they found, at least in the short term, is that xylitol nasal irrigations resulted in greater improvement of chronic rhinosinusitis symptoms as compared to saline irrigations.
