We hypothesized that although prevalent in the general population, nasal septal deviations differ structurally between OSA and non\u2010OSA patients. This study evaluated nasal septal deviation morphology in OSA versus non\u2010OSA patients using computed tomography (CT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We consecutively enrolled 128 adult patients undergoing septoplasty for nasal obstruction between April and September 2019. Seven with trauma\/surgery history were excluded. Polysomnography was performed preoperatively for those with significant sleep complaints. Using identical preoperative sinus CTs routines, we measured anterior, superior, and posterior deviation angles, comparing OSA and non\u2010OSA groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We studied 121 septoplasty patients (37 females, 84 males, mean age 45.73\u2009\u00b1\u20091.29\u2009years), with 34 OSA and 87 non\u2010OSA. Anterior deviation angle was significantly greater in OSA (mean 9.1\u2009\u00b1\u20090.7\u00b0) versus non\u2010OSA (mean 6.5\u2009\u00b1\u20090.5\u00b0) groups (p\u2009=\u20090.001). However, no significant superior or posterior deviation differences existed between groups (p\u2009=\u20090.266 and 0.231, respectively). Multiple logistic regression showed anterior deviation as the only significant independent OSA predictive factor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Among the nasal septal deviations, only the anterior deviation was associated with the presence of OSA.
