Cranioplasty for craniosynostosis may restrict cranial growth, leading to reduced intracranial volume (ICV) long-term. This study found significant ICV reduction in metopic synostosis patients and some sagittal synostosis patients post-surgery.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Craniofacial Surgery
Background:
- Craniosynostosis involves premature closure of cranial sutures, necessitating cranioplasty to correct deformities and manage intracranial pressure.
- While cranioplasty offers benefits, its impact on long-term cranial skeletal growth requires further investigation.
Purpose of the Study:
- To evaluate the long-term effect of cranioplasty on intracranial volume (ICV) in patients with isolated metopic or sagittal synostosis.
- To compare ICV changes between different surgical techniques and a control group.
Main Methods:
- Retrospective case-control study of 185 patients with metopic or sagittal synostosis undergoing cranioplasty (2002-2012).
- Computed tomography (CT) scans pre- and post-operatively (3 years) used for ICV measurement via MATLAB.
- Comparison with 414 age- and sex-matched controls.
Main Results:
- Statistically significant reduction in ICV observed in metopic synostosis patients post-surgery.
- Significant ICV difference noted in sagittal synostosis patients treated with Pi-plasty, but not with strip craniotomy and springs.
- 185 patients included pre-op, 160 post-op, compared to 414 controls.
Conclusions:
- Extensive cranioplasties for craniosynostosis can result in minor but significant long-term growth restriction.
- Reduced ICV is a notable outcome following surgical correction of metopic and sagittal synostosis.

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...
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...
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,...
