“…This suggests that the vomer in the UCLP group has an intermediate morphology between those in the BCLP and Control groups. The short upper dental arch length reported by Ye et al 13 supports this.…”

: We examined vomer morphology using 3-dimensional 3D analysis and investigated the in uence 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 signi cant 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 signi cantly 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 signi cantly greater in the BCLP group. P 0.05 . A signi cant difference was only found in the posterior vomer width between the UCLP and Control groups. The vomer volume was signi cantly larger in the BCLP group. The volume in the UCLP group was larger than in the Control group, but this was not signi cant. Factor analysis revealed that vomer morphology could be clearly distinguished between the 3 groups. Cleft-associated differences in the vicinity of the vomermaxilla palatine bone fusion may in uence 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.

“…rotated clockwise and the anterior part collapsed according to the fitting curve of the dental arch; the overall dental arch showed a ''V'' shape. Ye et al 19 reported a similar conclusion by measuring the dental cast CT. We also found that the UCLP patients have a more constrictive arch width than patients in the GIII group. However, the differences of the maxillary dental widths between the GIII and GN groups were not statistically significant.…”

This study is to investigate the anatomical features of maxillae in unilateral cleft lip and palate (UCLP) patients with maxillary retrusion. Additionally, the dissimilarities of retruded maxillae between the UCLP patients and the skeletal class III patients were compared. Craniofacial measurements were carried out among 32 UCLP adult patients with maxillary retrusion (GC), 24 adult patients in class III (SNA < 80°, ANB < 0°) patients (GIII), and 32 normal controls (GN). The authors measured the width and length of the maxillae, as well as their relative positions to the coronal plane passing through basion. The independent sample group t test was performed, and P < 0.05 was regarded as statistically significant. In the GC group, the anterior and posterior maxillary length (A1-P3M⊥CP and P3M-P6M⊥CP) and overall maxillary length (A1-P6M⊥CP) at the dental level, the interdental widths of the maxillae, the maxillary volume (GM), and the volume consisting of maxilla and maxillary sinus (GT) significantly reduced compared with the GN group (P < 0.05). The distances from the points on the maxillae to the coronal plane (A1⊥CP, P3M⊥CP, and P6M⊥CP) in the GC and GIII groups were smaller than those in the GN group (P < 0.05). In summary, for the UCLP patients, the decreased prominence of maxillary complex could be mainly caused by the shortened maxillary length; meanwhile, posterior position of the maxillary body may have some influence on the maxillary protrusion. While for the class III patients, maxillary retrusion was resulted from malposition and malmorphology on an equal basis.

“…In previous studies, by dental cast measurement we have found that although patients with unilateral cleft lip and palate (UCLP) have an imminent palatal tissue shortage, surgical cleft palate repair is the main cause of transverse constriction of maxillary arch (Ye et al, 2010(Ye et al, , 2012. In this study, we tried to reveal the influence of cleft palate malformation itself and operation on maxillary sagittal and vertical development, by lateral cephalometric analysis.…”

A Comparative Study on Dental-Arch Morphology in Adult Unoperated and Operated Cleft Palate Patients

Abstract: The influence of cleft palate on the development of maxillary arch is limited to the vicinity of the cleft in the anterior region only. Palatoplasty is the main cause resulting in the constriction of maxillary arch, while inhibiting the sagittal development of the anterior arch.
