Improved outcomes after low-concentration hypochlorous acid nasal irrigation in pediatric chronic sinusitis

Abstract

Objectives/HypothesisWe aimed to evaluate the effectiveness of low-concentration hypochlorous acid (HOCl) nasal irrigation compared to isotonic normal saline for pediatric chronic rhinosinusitis. Study DesignThis was a randomized, prospective, active-controlled study. MethodsThis study investigated the effectiveness of 4 weeks of low-concentration hypochlorous irrigation by analyzing five categorized subjective symptoms and x-ray findings in pediatric patients with rhinosinusitis. Thirty-seven patients were enrolled, and 26 patients successfully completed the study. ResultsTotal symptom scores significantly improved with both HOCl and normal saline nasal irrigation, but there was no difference between the two groups. X-ray scores also improved in both groups; improvement was much greater in the HOCl group than the placebo group. ConclusionsNasal irrigation with HOCl is an effective adjuvant treatment compared to isotonic normal saline for pediatric sinusitis. Level of Evidence1b Laryngoscope, 126:791-795, 2016
