Intracranial hypertension occurs in children with single-suture craniosynostosis. This finding suggests monitoring intracranial pressure is important for timely intervention and parental counseling in these cases.
Area of Science:
- Pediatric Neurosurgery
- Craniofacial Surgery
- Developmental Biology
Background:
- Traditionally, surgical correction for single-suture craniosynostosis focused on cosmetic outcomes.
- Intracranial hypertension is recognized in complex craniosynostosis but less studied in single-suture forms.
Purpose of the Study:
- To investigate the incidence of intracranial hypertension in children with single-suture craniosynostosis.
- To assess the relationship between suture involvement and intracranial pressure levels.
Main Methods:
- Retrospective study involving 74 children with single-suture craniosynostosis.
- Overnight subdural intracranial pressure monitoring was performed.
- Analysis of pressure readings based on the specific suture involved (coronal, sagittal, metopic).
Main Results:
- 17% of children had elevated intracranial pressure, 38% had borderline levels, and 45% had normal levels.
- Elevated intracranial pressure was more frequent in midline suture involvement (sagittal or metopic) compared to coronal suture fusion.
- Specific suture involvement: 37 coronal, 25 sagittal, 12 metopic.
Conclusions:
- Intracranial hypertension is a significant concern in a notable proportion of children with single-suture craniosynostosis.
- Intracranial pressure monitoring should be considered during the initial assessment of these patients.
- This approach facilitates timely intervention and informed parental counseling.

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,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
