Objective: The purpose of this study was to assess the ability of shape parameters of nasal morphology to predict esthetics in individuals with complete unilateral cleft lip and palate (CUCLP). Methods: This retrospective study involved 28 patients with repaired CUCLP. Nostril morphology was analyzed using nose casts and a video-imaging technique. Calculated shape parameters included area, perimeter, centroid, angle of the principal axis, major and minor moments of area, anisometry, bulkiness, lateral offset, and three-dimensional internostril angles. Esthetics was assessed using a panel of six orthodontists who rated nasal esthetics from frontal, lateral, basal, and three-quarters view slides and from nose casts. Correlations between esthetics and the shape parameters were completed using the entire group as well as using two statistically determined subsets: those with the best and those with the worst esthetics. Results: Nasal esthetics was related to only the perimeter and bulkiness parameter ratios. Symmetry of the perimeters between the right and left nostrils positively correlated with better esthetics using the entire sample group while symmetry of bulkiness between the right and left nostrils positively correlated with better esthetics using both the entire sample group and the best and worst subsets. Conclusions: Only perimeter and bulkiness showed positive correlations with nasal esthetics. The group of parameters used to assess nostril morphology had neither significant correlation with—nor predictive power for—esthetics. Thus, an assessment of the entire nasal surface topography in three dimensions needs to be completed and assessed with respect to predictability of nasal esthetics.

The purpose of the present study was to describe facial asymmetry in three dimensions in individuals with an operated complete unilateral cleft lip and palate (UCLP) and in individuals without craniofacial anomalies (controls). Three-dimensional coordinates for 16 bilateral and 10 midsagittal facial landmarks were determined for the UCLP group (N=49) and the control group (N=80) by means of stereophotogrammetry. The total asymmetry was measured and resolved for transverse, vertical, and sagittal components. It can be concluded that all three components are Important in studies on facial asymmetry. Individuals with UCLP show more facial asymmetry in the vertical direction than controls. They demonstrate more facial asymmetry in the region related to the cleft than controls. And, males in general demonstrate more asymmetry of the nose than females.

Studies on facial left-right dominance in individuals without craniofacial anomalies have demonstrated controversial results. This is probably due to the frequent use of two-dimensional methods, yet left-right dominance consists of transverse, vertical, and sagittal components. The aim of the present study was to describe three-dimensionally facial left-right dominance in individuals with an operated complete unilateral cleft lip and palate on the left side (LUCLP), on the right side (RUCLP), and in individuals without craniofacial anomalies (controls). Using stereophotogrammetry, three-dimensional coordinates for 16 bilateral and 10 midsagittal facial landmarks were determined for the LUCLP group (N=32), the RUCLP group (N=17), and the control group (N=80). Left-right dominance was measured in three directions. Individuals without craniofacial anomalies showed a facial left sided dominance in the transverse direction, a facial right sided dominance in the sagittal direction, and no particular dominated side in the vertical direction. Individuals with a unilateral cleft lip and palate demonstrated a facial dominance of the nonaffected side in the vertical direction as well as in the sagittal direction, with no particular side dominant in the transverse direction. Generally, there was more variation in left-right dominance within the face in the vertical and sagittal directions.

Aim: To demonstrate three-dimensional virtual modeling of a cleft lip and palate patient. Methodology: Traditional two-dimensional treatment planning modalities are often inadequate. Developing technology has enabled the virtual modeling of cleft lip and palate patients. Mimics software was used to demonstrate how to construct such a model. Conclusion: We are now able to model cleft lip and palate patients in three dimensions. How to cite this article: Karadede İ, Adıgüzel Ö, Özer T, Bilgiç F, Özhal İzol R.

Objective: To analyse the morphological presentation of orofacial clefts, gender, syndromes and systemic anomalies associated with them. Design: This was an epidemiological study performed in the patients who were registered for cleft lip and palate surgeries in our centre. The data was evaluated both retrospectively as well as prospectively. Patients/ Participants: The patients registered from November 2006 to April 2021 were studied. Out of 5276 patients, data of 5004 cases were analysed, rest 272 patients were excluded due to lack of information. Statistical analysis and Chi square test were applied. Results: Cleft deformities were more common in males than females. Cleft lip with palate was the commonest phenotype (52.2%). It was followed by isolated cleft lip (22.9%), isolated cleft palate (22.1%), rare clefts (1.62%) and syndromic clefts (1.18%). Unilateral variants were more frequent than bilateral. In unilateral, left side was more common than the right side. Among bilateral, most of the cases had premaxillary protrusion. In the present study, 3.46% of all the patients had associated anomalies affecting their other organs. Less common cleft phenotypes like microform cleft lip and submucous cleft palate ± bifid uvula showed frequency of 0.62% and 0.64% respectively. Conclusion: Thorough examination of cleft deformity should be done as it may appear as an isolated deformity or part of a syndrome and have associated systemic anomalies. This may help us to deliver comprehensive care to the patients and can prevent potential operative complications.

Objective To supply quantitative information about the facial soft tissues of adult operated patients with cleft lip and palate (CLP). Design, Setting, and Patients The three-dimensional coordinates of soft tissue facial landmarks were obtained using an electromagnetic digitizer in 18 Caucasian patients with CLP (11 males and 7 females aged 19 to 27 years) and 162 healthy controls (73 females and 89 males aged 18 to 30 years). From the landmarks, 15 facial dimensions and two angles were calculated. Data were compared with those collected in healthy individuals by computing z-scores. Two summary anthropometric measurements for quantifying craniofacial variations were assessed in both the patients and reference subjects: the mean z-score (an index of overall facial size), and its SD, called the craniofacial variability index (an index of facial harmony). Results In treated patients with CLP, facial size was somewhat smaller than in normal individuals, but in all occasions the mean z-score fell inside the normal interval (mean ± 2 SD). Almost all patients had a craniofacial variability index larger than the normal interval, indicating a global disharmonious appearance. Overall, in patients pronasale, subnasale, and pogonion were more posterior, the nose was shorter and larger, the face was narrower, and the soft tissue profile and upper lip were flatter than in the reference population. Conclusions The facial soft tissue structures of adult operated patients with CLP differed from those of normal controls of the same age, sex, and ethnic group. In this patient group, surgical corrections of CLP failed to provide a completely harmonious appearance, even if the deviations from the reference were limited. Further analyses of larger groups of patients are needed.
