de Gabory L, et al. - Researchers compared the effectiveness of a mineral-rich solution vs normal saline solution (0.9% NaCl) following endoscopic complete bilateral ethmoidectomy. They conducted a prospective, multicenter, randomized, controlled, open-label trial in subjects suffering from steroid-resistant sinonasal polyposis. Endoscopic scores and QoL after sinus surgery for patients over 60, those with an initially poor QoL and higher symptom score, and smokers are influenced by the composition of a nasal irrigation solution. Compared to the saline solution, less epistaxis was reported with the mineral solution.
