Insights
Cranial expansion surgery can successfully treat craniocephalic disproportion in children. This neurosurgical intervention resolved symptoms of raised intracranial pressure and restored cerebrospinal fluid (CSF) pathways in all evaluated cases.
Area of Science:
- Neurosurgery
- Pediatric Neurosurgery
- Craniofacial Surgery
Background:
- Craniocephalic disproportion presents complex treatment challenges, particularly when associated with conditions like slit ventricle syndrome.
- The optimal surgical approach for craniocephalic disproportion remains uncertain, necessitating evaluation of existing treatment modalities.
Observation:
- This study reviewed the outcomes of four pediatric patients who underwent cranial expansion surgery over a five-year period.
- Patient ages at surgery ranged from 16 months to 6 years.
- Surgical procedures included bilateral parietal expansions and posterior cranial vault expansion, with one patient also requiring craniocervical junction decompression.
Findings:
- All four patients experienced resolution of symptoms related to increased intracranial pressure following cranial expansion.
- Radiological assessments confirmed the re-establishment of normal cerebrospinal fluid (CSF) pathways post-operatively.
- The study included diverse etiologies, such as slit ventricle syndrome and non-syndromic craniosynostosis, with one case of vitamin D-resistant rickets.
Implications:
- Cranial expansion surgery demonstrates efficacy in selected pediatric cases of craniocephalic disproportion.
- These findings support cranial expansion as a viable neurosurgical option for managing complex craniofacial abnormalities.
- Further research into patient selection and long-term outcomes is warranted for this rare condition.
Abstract:
The appropriate treatment for craniocephalic disproportion, such as caused by slit ventricle syndrome, is uncertain. We have reviewed the treatment and outcomes of 4 children who underwent cranial expansion over a period of 5 years. The ages at cranial expansion were 16 months, 3 years 6 months and 2 at 6 years. Two children had slit ventricle syndrome and were treated with bilateral parietal expansions. Two children had non-syndromic craniosynostosis, one of these having vitamin D-resistant rickets. The latter 2 were treated with posterior cranial vault expansion, and one also had a craniocervical junction decompression performed. Post-operatively, symptoms of raised intracranial pressure resolved in all cases, and there was radiological evidence of re-establishment of normal CSF pathways. Although a rare condition, cranial expansion operations can be successful in appropriately selected cases of craniocephalic disproportion.

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...
