Insights
Craniosynostosis is a rare birth defect where skull sutures fuse early, potentially harming brain development. Deformational plagiocephaly, a common condition, causes head shape changes but does not impact brain function.
Area of Science:
- Pediatric Surgery
- Developmental Biology
- Craniofacial Medicine
Background:
- Craniosynostosis is a congenital condition involving premature fusion of cranial sutures, often evident at birth.
- Deformational plagiocephaly, a more common condition, typically appears by two months of age and involves flattening of the head.
- While deformational plagiocephaly is cosmetic, craniosynostosis poses risks to brain growth and development.
Observation:
- Craniosynostosis presents as a rare, congenital deformity with premature suture fusion.
- Deformational plagiocephaly is a common condition causing head asymmetry by two months of age.
- Infants with irregularly shaped heads require evaluation by a craniofacial surgeon.
Findings:
- Craniosynostosis can impede brain growth and development, making it a serious condition.
- Deformational plagiocephaly, though common, does not affect cognitive function.
- Early identification of these conditions is crucial for appropriate management.
Implications:
- Prompt medical evaluation is essential for infants with concerning head shapes.
- Understanding the distinctions between craniosynostosis and deformational plagiocephaly guides treatment decisions.
- This overview offers insights into the signs and updated treatments for these pediatric head shape abnormalities.
Abstract:
Craniosynostosis, a congenital deformity in which one or more of the sutures between the bones of the cranial vault fuse prematurely, is a relatively rare condition that is usually obvious just after birth. Deformational plagiocephaly is much more common and usually becomes apparent by 2 months of age. Although the head of a baby with deformational plagiocephaly may appear flat on one side, deformational plagiocephaly does not affect brain function. Craniosynostosis, however, may impair brain growth and development and, thus, is far more serious. Babies with irregularly shaped heads that are concerning should be evaluated by a craniofacial surgeon. This article provides an overview of the physical signs of craniosynostosis and deformational plagiocephaly as well as an update on treatment.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
