The spaces between a typical baby's skull bones are filled with flexible material and called sutures. The anterior fontanelle normally closes by 18 months of age, but there is a wide range of normality; the posterior fontanelle should be closed by 2 months of age and may already be closed in the neonatal period.

The fontanelles include: Anterior fontanelle (also called soft spot). Healthline Media does not provide medical advice, diagnosis, or treatment. The largest fontanel is at the front (anterior). This helps the newborn infant to learn to respond to many forms of external stimuli. If meningitis is suspected, a lumbar puncture should be performed to evaluate the cerebrospinal fluid for Gram stain, protein, glucose, cell count, and culture. There are four major sutures: the metopic, coronal, sagittal, and lambdoid. An unusual head shape may be due to craniosynostosis, premature closure of the sutures of the skull, or may represent a deformational process, caused by unusual forces acting on the otherwise normal skull. If any of the sutures close too early (fuse prematurely), there may be no growth in that area. Cranial malformations, although uncommon, compromise not only function but also the mental well-being of the person.

Liked what you read just now? In addition, CT scanning helps in evaluating the brain for structural abnormalities (e.g., hydrocephalus, agenesis of the corpus callosum) and in excluding other causes of asymmetric vault growth (e.g., brain hemiatrophy, chronic subdural hematoma).3 Three-dimensional surface reconstruction using CT scanning can help the surgeon to accurately delineate the craniofacial deformity and plan surgical reconstruction.27, The major complications associated with uncorrected craniosynostosis include increased intracranial pressure, asymmetry of the face, and malocclusion. The clinical features include misshapen skull caused by coronal suture synostosis, wide-set eyes, mid-face hypoplasia, choanal stenosis, and shallow orbits. Surgical staples can be an effective way to close wounds from surgery, to promote healing, and to help limit scarring. Inspect the face for symmetry. .

This is the junction where the2 frontal and2 parietal bones meet. Abnormal brain development that results in microcephaly also can cause a small anterior fontanel or early fontanel closure. In general, small babies and very large babies are at greater risk for problems. An infant born at term has nearly 40 percent of his or her adult brain volume, and this increases to 80 percent by three years of age. Pulsations of the fontanelles reflect the pulse. The objective of coronal synostosis is to increase the anteroposterior dimensions of the calvaria. It's always a big hit with everyoneespecially my family! The result is a symmetrically shaped head.
