A more detailed neurosonographic evaluation is done in additional coronal and sagittal planes, visualised ideally with transvaginal ultrasound through the anterior fontanelle. Place the vacuum cup on the occiput of the fetal cranium toward the anterior fontanelle. 1] The anterior fontanelle is the unossified area of the skull situated at the junction of the frontal, coronal, and sagittal sutures.
13,15 Normal Fontanel POSTERIOR FONTANEL At birth, the average size of the posteriorfontanel is 0.5 cm in white infants and 0.7 cmin black infants. 16 The fontanel usually is com-pletely closed by two months of age.10 ANTERIOR FONTANEL The key feature of a normal anterior fontanelis variation.On the first day of an infantâs life,the normal fontanel ranges from 0.6 cm to3.6 cm, with a mean of 2.1 cm. 17 Black infantshave larger fontanels (1.4 cm to 4.7 cm).6 The fontanel usually is com-pletely closed by two months of age. 10 ANTERIOR FONTANEL The key feature of a normal anterior fontanelis variation. On the first day of an infantâs life,the normal fontanel ranges from 0.6 cm to3.6 cm, with a mean of 2.1 cm.
