Insights
Three-dimensional computed tomography (3D CT) effectively diagnoses craniosynostosis in children. This imaging technique also identifies associated osseous defects in the cranial vault, aiding in surgical planning.
Area of Science:
- Medical Imaging
- Pediatric Surgery
- Radiology
Background:
- Craniosynostosis, the premature fusion of cranial sutures, affects infant skull development.
- Accurate diagnosis and characterization of bony abnormalities are crucial for effective management.
- Three-dimensional computed tomography (3D CT) offers advanced visualization of complex skeletal structures.
Purpose of the Study:
- To evaluate the diagnostic utility of 3D CT in identifying craniosynostosis in pediatric patients.
- To correlate cranial deformities with the presence of osseous defects in the cranial vault.
- To assess the reliability of 3D CT in detecting these abnormalities.
Main Methods:
- One hundred and two children with suspected craniosynostosis underwent spiral CT with 3D reconstruction.
- Shaded Surface Display (SSD) and Volume Rendering (VR) algorithms were used for 3D visualization.
- Osseous defects were evaluated and correlated with craniosynostosis type and cranial vault shape.
Main Results:
- 3D CT successfully diagnosed craniosynostosis in all evaluated patients.
- All patients presented with combined forms of craniosynostosis.
- Osseous defects were identified in 56 patients, with specific findings noted for scaphocephaly, plagiocephaly, and trigonocephaly.
Conclusions:
- 3D CT is a safe and reliable method for diagnosing craniosynostosis in children.
- The technique effectively identifies associated osseous defects in the cranial vault.
- 3D CT aids in comprehensive assessment for surgical planning in pediatric craniosynostosis cases.
Abstract:
This study assessed the value of three-dimensional CT (3D CT) in the diagnosis of craniosynostosis, and correlated the cranial deformity with the presence of osseous defects in cranial vault's bones. One hundred and two children (55♀ and 47♂) with a clinical suspicion of craniosynostosis, underwent spiral computed tomography with 3D reconstruction using the shaded surface display (SSD) and volume rendering (VR) algorithms. We evaluated the presence of osseous defects in cranial bones in correlation with the type of craniosynostosis and the shape of the cranial vault. 3D CT allowed the evaluation of craniosynostosis in all patients. All patients had combined forms of craniosynostosis. Osseous defects in the bones of cranial vault were found in 56 patients of whom nine had scaphocephaly, eight plagiocephaly and one trigonocephaly. CT of the skull with three-dimensional reconstruction can safely and reliably identify craniosynostoses in children and could be used for the identification of osseous defects in the cranial vault.

01:22Sutures 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...
01:27Cranial 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...
01:14Cranial 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,...

The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
