Abstract
The lateral roentgencephalograms of 29 children with repaired complete bilateral clefls or the lip and palate (BCLP) were compared with those of an equal number of non—cleft children matched for age (Lt-0.9 yr.) and sex. Of 21 spatial, angular, and linear measurements used to evaluate craniofacial skeletal morphology, 11 showed significant differences between the groups. Usingfactor analysis, covarz'ation between variables was reduced to a set of six factors: I cranial bare; II mandible; III palate; IV lower face; V nasomaxillary-p/zaryngeal complex; VI clivus. The six-factor solution accounts for 91.7 percent of the variance. Factors II, III, and V provide the best discrimination between BCLP and noncleft individuals.
