 note = {We examined vomer morphology using 3-dimensional (3D) analysis and investigated the influence of the surrounding sutures (clefts) and maxilla on nasal septum (vomer) morphology. We evaluated 60 patients who visited our institution. Patients underwent lateral cephalometry and cone-beam computed tomography (CBCT) upon initial examination. Patients with no significant differences in cranial growth were selected and divided into 3 groups of 20: the bilateral cleft lip and palate (BCLP), unilateral cleft lip and palate (UCLP), and non-cleft (Control) groups. We investigated vomer and facial morphologies by using 2-dimensional (2D) cephalometry and we also determined vomer morphology by using 3D cephalometry. Results were analyzed using Bonferroni multiple comparison, logistic regression analysis, and factor analysis. Vomer morphology was significantly different between the 3 groups. Sagitally, the vomer shape was a narrow quadrilateral that tapered at one end in the BCLP group, trapezoidal in the Control group, and intermediate, like a parallelogram, in the UCLP group. The vomer width was significantly greater in the BCLP group. (P <0.05). A significant difference was only found in the posterior vomer width between the UCLP and Control groups. The vomer volume was significantly larger in the BCLP group. The volume in the UCLP group was larger than in the Control group, but this was not significant. Factor analysis revealed that vomer morphology could be clearly distinguished between the 3 groups. Cleft-associated differences in the vicinity of the vomer–maxilla (palatine bone) fusion may influence vomer formation and may cause the differences observed in vomer morphology between the 3 groups. This suggests that cleft and maxillary morphologies may affect nasal septum morphology.},
