Background: Montelukast is used in the treatment of allergic rhinitis and asthma. It has been used as adjuvant therapy in patients with chronic rhinosinusitis (CRS), but its effectiveness has not been evaluated. This study evaluates the efficacy of adjuvant leukotriene receptor antagonism in CRS and subtypes. Methods: Retrospective review of collected data at a tertiary-referral institution. We identified all patients who were prescribed montelukast postoperatively and had a lapse in therapy for at least 1 month (n = 50), so that the patients themselves serve as their own control group. Twenty-item Sino-Nasal Outcomes Test (SNOT-20) scores and Lund-Kennedy endoscopy scores were obtained for each patient. Scores were compared with and without montelukast using Wilcoxon signed rank test. The analysis was controlled for changes in other medications. Results: Fifty-two therapy lapses were identified in 50 patients. Twenty-seven patients had eosinophilic CRS with polyps (eCRSwNP), 8 had Samter's triad (ST), and 15 had allergic fungal sinusitis (AFS). Overall mean follow-up was 46.5 months. Overall, SNOT-20 scores and endoscopy scores were significantly lower with montelukast (p < 0.005 for both). On subgroup analysis, SNOT-20 scores were significantly improved for patients with eCRSwNP and AFS (p < 0.001 and p = 0.001, respectively). Endoscopy scores were significantly improved for patients with eCRSwNP (p = 0.044). Outcomes approached, but did not reach, significance for patients with ST (p = 0.123 for SNOT-20 and p = 0.146 for endoscopy). There was also significant improvements in patients with asthma. Conclusion: The addition of montelukast as postoperative therapy may be beneficial for patients with eCRSwNP and AFS.
