Determination of Anterior Fontanelle Size among Apparently Healthy Term Newborns in North Central Nigeria.

Background: Anterior fontanelles (AFs) of healthy newborn infants vary widely in size, this being a function of race, geographical location, gender, birth weight, mode of delivery and gestation. Abnormal variations in AF size portend a serious pathology of the cranium or intracranial structures. The established reference value for normal AF size is, therefore, an essential diagnostic tool.
