Roentgenographic cranial-base and calvarial measurements of north Indian children from birth to two years of age.

In order to establish norms for dimensions of the skull in North Indian children, lateral skull films of 166 apparently healthy, normocephalic children between birth and two years of age were studied. Using bony reference points, measurements were made of cranial-base length and calvarial height. It appears that there is definite proportionality between growth of ventral and posterior cranial-base, calvarium and ventral base, and anterior and posterior calvarium, at all ages and for both sexes. Deviation in these proportions may suggest abnormality in a corresponding area of the cranium.
