[Radiological considerations of cranio-facial volumetry in the newborn (author's transl)].

The authors have reported that the wide range of sizes of the normal skull, make difficult the assessment of macrocephaly and microcephaly of mild degree. For this fact they studied and applied a simple method based on the measurement of the cranial capacity and facial volume and on their relationship; they have calculated the "cranio-facial ratio" (CFR), in 42 normal newborns (21 females and 21 males), whose range is sufficiently delimited, consenting a more precise judgement in pathological field.
