Cleft Palate J. 1980 Jul;17(3):234-44.
The lateral roentgencephalograms of 29 children with repaired complete bilateral clefts of the lip and palate (BCLP) were compared with those of an equal number of non-cleft children matched for age (+/- 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. Using factor analysis, covariation between variables was reduced to a set of six factors: I cranial base; II mandible; III palate; IV lower face; V nasomaxillary-pharyngeal 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.
对29例双侧唇腭裂（BCLP）修复术后儿童的侧位头颅X线片与年龄（±0.9岁）和性别匹配的同等数量非腭裂儿童的侧位头颅X线片进行了比较。在用于评估颅面骨骼形态的21项空间、角度和线性测量中，11项显示两组之间存在显著差异。通过因子分析，变量之间的协变量被简化为一组六个因子：I颅底；II下颌骨；III腭部；IV下面部；V鼻上颌-咽复合体；VI斜坡。六因子解解释了91.7%的方差。因子II、III和V在BCLP个体和非腭裂个体之间提供了最佳区分。
