“…Our evaluation of mandibular asymmetry indicated that the mandible was not affected in UCCLP, as more significant asymmetries were detected in the Class I control group. These results accord with previous findings (7,28).…”

“…A three-dimensional study of adults revealed no distinctive midfacial hard-or soft-tissue asymmetries between the affected and unaffected sides in individuals with nonsyndromic unilateral cleft lip and palate (7). However, some researchers found greater asymmetry in CLP patients than in controls, particularly in the midface (27).…”

“…Computed tomography was used to evaluate facial asymmetry and sagittal and vertical facial morphology; however, these studies were uncontrolled and restricted to a small number of CLP patients (7,10,11). The differences in the three-dimensional (sagittal, horizontal and vertical planes) growth characteristics of CLP patients and Class I individuals are a matter of controversy.…”

Three-dimensional craniofacial morphology in unilateral cleft lip and palate

Craniofacial morphology and asymmetrywere compared before, during, and after puberty within and between patients with unilateral complete cleft lip and palate (UCCLP) and a non-cleft group. In the UCCLP group, the posterior cranial base and total cranial base were significantly shorter at all skeletal periods, the maxilla was significantly retruded and posteriorly rotated, and the mandible was significantly smaller and inferoposteriorly rotated. The angle between the nasal and mandibular plane and lower anterior facial height were significantly higher, and upper posterior facial height and total posterior height were significantly lower, in the UCCLP group. Except for an increase in the nasal cavity, no significant differences were detected in facial width. For all measurements, asymmetry on the horizontal plane was more significant than that on the vertical plane. Asymmetries in the UCCLP group were mostly detected during puberty. The UCCLP group had no distinctive mandibular asymmetry, as compared with the Class I group. In UCCLP patients, the cranial base, maxilla, and mandible were affected on the sagittal plane during all growth periods. However, horizontal asymmetries were mostly detected before and during puberty. Vertical asymmetries were less severe, and there was no distinctive mandibular asymmetry as compared with the Class I group. (J Oral Sci 56, 165-172, 2014)

“…Beside that, deformity of the nasal rim, including flattening of the nostril of the affected side, is observed. This is a result of the presence of scarring [3,4]. The asymmetry is also observed in hard tissues and refers mainly to the dentoalveolar region that is retruded and rotated backwards at the affected side [3][4][5].…”

The Nasolabial Angle Among Patients with Total Cleft Lip and Palate

Background. Nasolabial angle is the angle that is measured between points columella, subnasale and labiale superius. The reference values vary from 90 to 120 degrees (the mean value is 109.8 degrees). In some disorders, nasolabial angle might change. This influences the facial profile. One of such deformities are clefts. The nasolabial angle might be decreased in cleft patients due to deformation of the nose and upper lip that might be caused by the reconstructive surgical procedures performed. Objectives. The aim of the study was to compare the nasolabial angle between the groups of patients with total clefts of the lip, alveolar bone and palate and healthy individuals. Material and Methods. The cephalometric X-rays of 118 patients with clefts (73 boys and 45 girls) and 101 healthy individuals (32 boys and 69 girls) were taken into account to measure nasolabial angle and compared. Results. In patients with cleft deformities, the nasolabial angle values were smaller than in healthy individuals. Among the patients with clefts, the ones with a bilateral type of deformity are characterized by the highest mean values of nasolabial angle. The angle is smaller in groups of girls when compared to boys. Conclusions. Nasolabial angle in patients with total clefts of lip, alveolar bone and palate is statistically smaller than in healthy individuals. This might be a result of either the deformation of the upper lip or (more probably) the nose. The orthodontic treatment should be individualized (Adv Clin Exp Med 2015, 24, 3, 481-485).

Nasal airway and septal variation in unilateral and bilateral cleft lip and palate

et al. 2014

View full text Add to dashboard Cite

Cleft lip and palate (CLP) affects the dentoalveolar and nasolabial facial regions. Internal and external nasal dysmorphology may persist in individuals born with CLP despite surgical interventions. 7-18 year old individuals born with unilateral and bilateral CLP (n 5 50) were retrospectively assessed using cone beam computed tomography. Anterior, middle, and posterior nasal airway volumes were measured on each facial side. Septal deviation was measured at the anterior and posterior nasal spine, and the midpoint between these two locations. Data were evaluated using principal components analysis (PCA), multivariate analysis of variance (MAN-OVA), and post-hoc ANOVA tests. PCA results show partial separation in high dimensional space along PC1 (48.5% variance) based on age groups and partial separation along PC2 (29.8% variance) based on CLP type and septal deviation patterns. MANOVA results indicate that age (P 5 0.007) and CLP type (P 0.001) significantly affect nasal airway volume and septal deviation. ANOVA results indicate that anterior nasal volume is significantly affected by age (P 0.001), whereas septal deviation patterns are significantly affected by CLP type (P 0.001). Age and CLP type affect nasal airway volume and septal deviation patterns. Nasal airway volumes tend to be reduced on the clefted sides of the face relative to non-clefted sides of the face. Nasal airway volumes tend to strongly increase with age, whereas septal deviation values tend to increase only slightly with age. These results suggest that functional nasal breathing may be impaired in individuals born with the unilateral and bilateral CLP deformity. Clin. Anat. 00:000-000,
