[Parameters of the facial bones in the fetus. Anthropology and medico-legal application for the determination of the fetal age].

From 93 skulls and 23 foeto-skeletals we give a glimpse of the rhythme of the human foetuse's facial bones growth and the main variations for facial measurements rating during foetal period. The best correlation between foetal age and facial measurements was obtained with facial height (correlation coefficient: 0.96). Evolution of cranio-facial rating, during foetal stages shows essentially: the increase of the height/width facial rating, the same rhythme of growth for frontal and facial width, the rapidly growth of biparietal diameter up to 30 amenorrhea weeks comparatively to the facial and frontal growth in width.
