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.
The diagnosis of an abnormal fontanel requires an understanding of the wide variation of normal. At birth, an infant has six fontanels. The anterior fontanel is the largest and most important for clinical evaluation. The average size of the anterior fontanel is 2.1 cm, and the median time of closure is 13.8 months.NTERIOR FONTANEL. The key feature of a normal anterior fontanel is variation. On the first day of an infant's life, the normal fontanel ranges from 0.6 cm to 3.6 cm, with a mean of 2.1 cm.
