[Tridimensional vestibular study of important aspects of the human frontal region during growth]. / Etude vestibulaire tridimensionnelle des points remarquables de la région frontale humaine au cours de la croissance.

The frontal bone, during its growth, has been analysed in the three dimensions of space, oriented by the vestibular axes of reference by the means of the coordinates of its noteworthy points, its notable linear measures and the distance of its elements relatively to the center of the axes. Its variability has also been explained by the construction of equiprobable ellipses of tolerance. These ellipses show the part due to growth and the part due to variation, the latter being more pronounced on the level of the dome of the skull than on the level of the basis.
