Protect your child from an accidental trauma to the head by placing bumper pads in the crib, properly installing car seats, and eliminating unstable objects from the childs environment.

Craniosynostosis occurs when one or more of the fibrous joints between the bones of a baby's skull (cranial sutures) close prematurely (fuse), before the brain is fully formed. The spaces between a typical baby's skull bones are filled with flexible material and called sutures. It actually implies overriding of skull bones at suture lines, which is felt as a ridge of bone when examined by passing fingers over the cranium. Assessment of fontanelles is an important part of the six week check. This makes the bony plates overlap at the sutures and creates a small ridge. Surgical staples can be an effective way to close wounds from surgery, to promote healing, and to help limit scarring. This allows the bone to enlarge evenly as the brain grows and the skull expands. These changes aid delivery through the birth canal and usually resolve after three to five days. Many patients have a family history of abnormal head shape.

This introduction is not intended to be comprehensive, but is instead designed to cover the main components of the newborn examination. Sutures allow the bones to move during the birth process. Additionally, findings such as overriding sutures (as are frequently seen in benign positional plagiocephaly) can also be well demonstrated on US by visualizing the echogenic calvarial plates overlapping one another at the location of sutures (Fig. The frontal bone flattens, the occipital bone is pulled outward, and the parietal bones override. This content is owned by the AAFP. The etiology of nonsyndromic craniosynostosis is unknown, and the condition is sporadic in most instances. - Also read "Effect of Vacuum Assisted LSCS (Caesarean Section) Delivery on the Baby", Have a Question?

The cranial fontanelles and sutures have several benign variations, including most cases of "early" or "late" closure of the anterior fontanelle, bathrocephaly, overriding sutures, and benign metopic ridging. The fontanel sometimes can be open but difficult to detect during a physical examination. In the photo above, the lingual frenulum under the tongue is restricting tongue elevation when the baby cries. Even so, birth traumas do occur. Cephalohematoma (sub-periosteal bleed) is occasionally noted. Isolated sagittal synostosis is the most common type of craniosynostosis. The most common disorders are meningitis, encephalitis, hydrocephalus, hypoxic-ischemic injury, trauma, and intracranial hemorrhage.20 Table 320 lists the differential diagnoses for a bulging fontanel.

Nucleotide alterations causing amino-acid substitutions at the FGFR2 gene on chromosome 10 lead to the Crouzon phenotype. Search the site! The head of an infant born by caesarean section or from a breech presentation do not undergo moulding and is characterized by its roundness. The normal movement of the fetal head through the birth canal produces a marked molding of the very soft fetal skull and scalp edema. These changes. The infant in the photo above has unusually prominent ribs as a result of intercostal retractions, a sign of respiratory distress. Dermoid tumors of the scalp are the most frequent lesions presenting over the anterior fontanel and also may be found over the posterior fontanel.29,30 They usually are slow-growing and nontender, and they are twice as common among girls. Effects on newborn health need to be observed closely: Extremes of mothers age; too young or too old. These excellent articles were published in the American Family Physician in 2002. Pay it forward! Closure of the coronal sutures leads to brachycephaly, in which the head is short in the antero-posterior diameter and wider laterally. This is used when time and length are a factor. The result is a symmetrically shaped head. The anterior fontanelle is located at the junction of the sagittal and coronal sutures, is usually 1.5 to 2.5 inches (4 to 6 cm) in diameter, and appears diamond-shaped. In select cases, such as newborns with multiple hemangiomas or heart failure, the anterior fontanel is auscultated to detect a bruit, which can indicate an arteriovenous malformation.10 Palpation of the fontanel in the upright position may reveal a normal, slight pulsation. The fontanelles include: Anterior fontanelle (also called soft spot). Craniosynostosis and symmetric syndactyly of the extremities are hallmarks of this syndrome. This is the junction where the2 frontal and2 parietal bones meet. Neonates are very sensitive to external stimuli during the first week of life. Is it common for bony ridges to be felt at skull suture lines if the investigations are normal? The skull may be molded, especially if the labor was prolonged and the head was engaged for a long period. The word fontanel is derived from the Latin fonticulus and the Old French fontaine, meaning a little fountain or spring.13 The normal fontanel varies widely in shape and time of closure.
