Evaluation of Parental Nasomaxillary Asymmetry as a Risk Factor for Development of Palatal Clefts in their Offsprings.

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.
