Abstract
STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is a multilevel problematic disease. Major septal deviation (SD) can lead to severe nasal congestion, which, in turn, can lead to sleep apnea. Although SD seems to be related to OSA, very few studies have quantitatively examined this relationship. In this study, we investigate this using a 9-year large-scale cohort study. METHODS: The SD group was selected out of 1 million individuals randomly extracted by the National Health Insurance Service. The non-SD group was obtained through propensity score matching considering several variables. The primary end point was OSA diagnosis. RESULTS: The study (SD) group included 11,238 individuals and the non-SD group (control group) included 22,476 persons. The overall hazard ratio for OSA in the SD group was 4.39 (95% confidence interval [CI]: 3.56-5.42). In subgroup analysis, the hazard ratio for OSA of male individuals was 3.77 (95% CI: 2.83-5.03), high economic status was 1.27 (95% CI: 1.05-1.56), metropolitan area was 1.31 (95% CI: 1.07-1.62), young age was 0.79 (95% CI: 0.64-0.98), hypertension was 1.00 (95% CI: 0.37-2.7), and diabetes mellitus was 2.44 (95% CI: 1.15-5.21). In the SD group, the hazard ratio for OSA after septoplasty was 0.71 (95% CI: 0.54-0.94). CONCLUSIONS: From long-term follow-up, the prevalence of OSA was 4.39 times higher in the SD group compared with the control group. This phenomenon was more pronounced with increasing body mass index and decreased significantly after septoplasty. CITATION: Yeom SW, Chung SK, Lee EJ, et al.
