Objective: The purpose of this study was to evaluate the transverse craniofacial form in families with nonsyndromic cleft lip and palate (NSCLP). It was hypothesized that affected as well as noncleft NSCLP family members are characterized by a common array of craniofacial features that differ from the general population. Design: This was a prospective cross-sectional investigation that included affected children with NSCLP and their noncleft parents and siblings. Patients, Participants: A total of 114 subjects (14 affected girls, 17 affected girls, 15 unaffected male siblings, 10 unaffected female siblings, 29 unaffected biological mothers, and 29 unaffected biological fathers) were included. Subject records comprised of posteroanterior cephalometric radiographs obtained from all 114 subjects. Main Outcome Measures: The width of midfacial structures, including the orbit and nose, was increased in NSCLP families, compared with published norms. Interestingly, the face was disproportionally wider in relation to total facial height. The transverse craniofacial form of children with or without clefts significantly correlated with that of their parents. Mothers displayed strong correlation with their affected and unaffected sons, whereas fathers correlated to their daughters, suggesting a possible sex-linked developmental influence. Conclusion: Better understanding of the genetic inheritance of craniofacial features associated with cleft lip and palate may ultimately contribute to the development of cleft risk assessment methods.
