This study evaluated the associations of NSD severity and continuous nasal septal deviation angle (NSDA) with computed tomography (CT)-derived nasal morphometric parameters. Methods: This retrospective cross-sectional study included 150 adults, with 50 in each NSD severity category. HC3-robust analysis of covariance adjusted for age, sex, and deviation side was applied across nine morphometric outcomes with false discovery rate (FDR) correction. Secondary models treated NSDA as a continuous exposure. Reliability was assessed in a severity-balanced 50-case subset. Results: Adjusted group effects were significant for the frontal facial angle (FFA), the internasal angle (INA), both nasal bone length-to-nose length (NBL\/NL) ratios, and root-based nose length (R-NL; FDR-adjusted p = 0.008\u20130.049). Severe deviation was associated with a lower INA and lower ratios than mild deviation, and with greater R-NL and FFA than moderate deviation. Continuous models confirmed a lower INA, lower ratios, and lower suture-based nasal bone length, and greater R-NL, per 5\u00b0 higher NSDA. Decomposition indicated that the lower suture-based ratio was driven mainly by lower nasal-bone length, whereas the lower root-based ratio was driven mainly by greater nose length. Interobserver intraclass correlation coefficients were 0.870\u20130.970. Conclusion: Greater NSD severity was associated with lower NBL\/NL ratios and INA and greater R-NL in this severity-balanced cohort. These findings characterize anatomical covariation in nasal proportion and geometry; their value for surgical decision-making requires prospective evaluation.<\/jats:p>","DOI":"10.1159\/orl\/aegag012","type":"journal-article","created":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T16:01:49Z","timestamp":1792425709000},"source":"Crossref","is-referenced-by-count":0,"title":["Nasal Morphometric Differences Associated with Septal Deviation Severity on Computed Tomography: A Cross-Sectional Anatomical Study"],"prefix":"10.1159","author":[{"given":"Hilal Melis","family":"Altintas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00f6zde","family":"Cing\u00f6z","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tug\u00e7e","family":"Akin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Hira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"K\u00f6ksal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Berin","family":"Tugtag Demir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,10,16]]},"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/orl\/aegag012","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T16:01:50Z","timestamp":1792425710000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/orl\/aegag012"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/orl\/aegag012","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,16]]}}}
