Background: Nasal septal deviation (NSD) is one of the most prevalent upper airway diseases causing airway obstruction, and it can negatively impact patients' quality of life (QoL)., Objective: The aim of this study was to determine the risk of anxiety and depression mood disorders in patients with NSD., Methods: A systematic review and meta-analysis was performed according to the PRISMA statement. An electronic search was performed on PubMed/MEDLINE, Scopus and Google Scholar. Raw affect size data were pooled comparing standardized between group mean differences., Results: A total of 625 patients (males: 53 %, n = 280/525) with a mean age of 32.4 years (n = 375, 95 % CI: 25.3-39.4) were included. The pooled standardized mean differences (SMD) for the prevalence of the anxiety disorder was 1.17 (n = 625, 95 % CI: 0.34-2.0). The pooled SMD for the prevalence of the depression disorder was 0.30 (n = 490, 95 % CI: 0.12-0.48)., Conclusion: Prevalence of anxiety and depression mood disorders is higher in patients with NSD compared to controls. These diseases should be investigated and considered during the diagnostic and therapeutic process to improve the QoL of patients with NSD., Competing Interests: Declaration of competing interest All other authors have no conflict of interest to disclose., (Copyright © 2022 Elsevier Inc.
