Cranial circumference of premature children.

Because there is only a little published information regarding the cranial circumference a t birth of premature infants, measurements have been performed in infants in order to elucidate this question. The largest circular fronto-occipital circumference has been measured at the point where the circular fronto-occipital circumference is greatest. All the measurements were made with the same tape measure. All measurements were on healthy infants, since infants, for instance those with cyanosis, convulsions, harelip, cleft palate and mongolism were excluded, as were infants of diabetic mothers. In addition the cranial circumference of a number of older children admitted to the Paediatric Department of Rigshospitalet was measured, and in this survey only those cases showing disturbances of growth or mental function (including oligophrenia) were omitted.
