“…In particular, our finding of a smaller nasal and maxillary width in the ipsilateral side of the parents contrasted with an increased nasal and maxillary width found in Suzuki A et al (1991) 6 , Raghavan R et al (1994) 7 , AL Emran SE et al (1999) 11 , and Yoon YJ et al (2003) 13 . This could be due to morphogenetically distinct study sample as compared to other geographic areas and ethnic grouping.…”

Background and Objectives : It has been suggested previously that increased width of midfacial structure is associated with the development of palatal clefting. One of the most important heritable characteristics predisposing towards the development of orofacial clefting in an embryo is craniofacial morphology. The aim of the study was to compare nasomaxillary width of parents of children with unilateral complete cleft lip alveolus and palate with parents of noncleft children.

“…The corresponding analytical approach is based on the construction of some composite synthetic traits from the original raw measurements. Although not widely practiced, this approach has been implemented in several quantitative genetic studies of head-size-and head-shape-related traits (Suzuki and Takahama 1991;Carels et al 2001;Ermakov et al 2005).…”

The substantial involvement of genetic factors in the determination of head-size and head-shape traits has been firmly established. However, there has been a lack of agreement on a number of specific issues concerning the pattern of inheritance of craniofacial features. In this study we examined some of these issues in a large, ethnically homogeneous sample of Indian pedigrees. The data included 1,263 individuals belonging to 373 nuclear families. Eleven raw head-size traits and two synthetic phenotypes, interpreted as horizontal and vertical head-size components (HOC and VEC, respectively), were used in the analysis. To establish the pattern of inheritance of head traits, we carried out univariate and bivariate analyses. Maximum heritability estimates ranged from 0.41 to 0.83 for the studied head-size phenotypes. The portion of the total residual variance attributable to putative additive genetic factors was 68.3% and 70.3% for HOC and VEC, respectively, and common familial factor effects were found to be nonsignificant. The extent of genetic influences did not differ significantly with respect to sex or between HOC and VEC. The results of bivariate variance decomposition analysis strongly suggest the existence of common genetic factors simultaneously affecting HOC and VEC; 41.8% of the two traits' total residual variance was attributable to the effect of these common genetic factors.

In the context of orthodontic treatment planning, the decisions to be made are often affected by the assumption of future growth patterns, especially the direction of mandibular rotation. Using longitudinally available lateral cephalograms from the Belfast Growth Study, it was examined whether, on the basis of the cephalometric variables at the ages of 7, 9 and 11, the direction of mandibular rotation can be predicted in the respective subsequent 4-year intervals. For statistical analysis of this problem, logistic regression models were applied to describe and quantify the influence of potential explanatory variables on the direction of mandibular rotation (dependent variable). In addition, graphical methods taken from the field of medical diagnostics were applied for prediction and for determination of predictive accuracy. The use of logistic regression models revealed no relations between the explanatory variables SN-MeGo and S-Go/N-Me and the subsequent mandibular growth pattern. Only the upper and lower parts of the gonial angle showed a minor predictive impact. A graphical evaluation of their prognostic impact by means of "receiver operating characteristics" (ROC) curves, complemented by determination of the areas under the curves, confirmed the relations discovered. Nevertheless the prognostic limits of the lateral cephalogram emerged clearly for all variables investigated.
