Pistacia Lentiscus Oil Nasal Spray With Reduced-Dose Mometasone in Chronic Rhinosinusitis

Brief Summary

Chronic rhinosinusitis (CRS) is a persistent inflammatory disease of the nose and sinuses. Medical treatment is mainly based on topical therapies aimed at controlling mucosal inflammation and improving naso-sinus clearance, including intranasal corticosteroids and nasal saline irrigations. This interventional, prospective, single-arm, single-sequence, two-period study aims to evaluate the maintenance of clinical control of chronic rhinosinusitis during dose reduction of mometasone and introduction of Bactorinol® nasal spray, in order to evaluate the possible compensatory role of the medical device compared with the full dose of mometasone. Participants will receive mometasone furoate nasal spray 2 puffs daily during the first 12 weeks, followed by 12 weeks of mometasone furoate nasal spray 1 puff daily combined with Bactorinol® nasal spray 3 puffs per nostril twice daily. Clinical outcomes will be compared between the two treatment periods.
