Methods: 326 subjects (including 168 Caucasians and 158 African-Americans) from a genetic epidemiological family study were studied. Standardized lateral cephalograms and facial photograms were taken for each subject. Six traditional cephalometric measurements and 8 photographic measurements were used.Descriptive statics for all measurements were computing using the Statistical Pacakages for Social Science(SPSS8.0). Results: Most photographic measurements demonstrated moderate correlation with cephalometric measurements. Some of them showed a good correlation. In the African-American group, the coefficients of mandibular length and anterior facial height between cephalometric and photographiic analysis were 0.676 and 0.690 repectively, the coefficient of skeletal and facial height was up to 0.521. Conclusions: 1. Cephalogram and facial photogram measure different aspects of craniofacial morphology and can not be interchanged. 2. Anterior facial height and mandibular length can be estimated with standard facial photogram. 3. Our results suggests that photographic analysis can be used as a valuable tool in clinical practice as well as genetic epidemiological studies.
