Posterior distraction osteogenesis successfully expanded the occiput in syndromic craniosynostosis patients, reducing intracranial pressure (ICP) and improving head shape. This technique offers a reliable method for posterior calvarial expansion in infants and children.
Area of Science:
- Craniofacial Surgery
- Pediatric Neurosurgery
- Distraction Osteogenesis
Background:
- Posterior occipital advancement treats raised intracranial pressure (ICP) in syndromic craniosynostosis.
- Distraction osteogenesis is increasingly used for craniofacial reconstruction.
- Its application in the posterior calvarium is relatively recent.
Observation:
- A retrospective review of 10 syndromic craniosynostosis patients undergoing posterior distraction (2007-2010).
- Mean patient age was 18.1 months, with the youngest being 3 months.
- Mean calvarial advancement achieved was 19.7 mm.
Findings:
- Successful clinical and radiological calvarial expansion in all 10 patients.
- Observed reduction in turricephaly and improved cephalic index.
- Resolution of raised intracranial pressure (ICP) was noted post-procedure.
Implications:
- Posterior distraction osteogenesis is a safe and effective technique for occipital expansion in syndromic craniosynostosis.
- Customized surgical techniques enhance patient-specific outcomes.
- This method increases the reliability of expansion in the posterior calvarium.

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...
01:14Cranial 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,...
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...
