Alternative The infant can be lying prone or supine with the skull again viewed from above.

Remarks An alternative method for determining fontanelle size is to calculate the area of the fontanelle (AC BX)/2 in square millimeters (Fig. 7.25). An usually small anterior fontanelle may be caused by craniosyn-ostosis involving the coronal and/or sagittal sutures. Males have a slightly larger anterior fontanelle than females for the first six months of life.

Pitfalls Occasionally, in a young child, the sagittal suture is widely patent and communicates with the posterior fontanelle, making definition of the landmarks more difficult. The anterior fontanelle may extend anteriorly into an open metopic suture.
