The few studies investigating the relationship between nasal septum deviation (NSD) and maxillary development, using different assessment methods and the age of subjects, reported contradicting results. The association between NSD and transverse maxillary parameters was analyzed using 141 preorthodontic full-skull cone-beam computed tomography scans (mean age, 27.4 ± 9.01 years). Six maxillary, 2 nasal, and 3 dentoalveolar landmarks were measured. The intraclass correlation coefficient was used to assess intrarater and interrater reliability. The correlation between NSD and transverse maxillary parameters was analyzed using the Pearson correlation coefficient. Each transverse maxillary parameter was compared among 3 groups of different degrees of severity using the analysis of variance test. Transverse maxillary parameters were also compared between the more and less deviated nasal septum sides using the independent t test. A correlation between deviated septal width and palatal arch depth (r = 0.2, P
