Insights
This study tracked cranial vault growth in children after surgery for sagittal craniosynostosis. While initial results improved head shape, long-term analysis showed a slight, clinically insignificant shift towards dolichocephalic growth.
Area of Science:
- Pediatric Neurosurgery
- Craniofacial Surgery
- Anthropometry
Background:
- Sagittal craniosynostosis correction techniques lack consensus on optimal surgical timing and procedures.
- Long-term anthropometric analysis is crucial for understanding cranial vault growth patterns post-intervention.
Purpose of the Study:
- To collect serial anthropometric data in children undergoing total cranial vault remodeling for sagittal craniosynostosis.
- To evaluate the long-term cranial vault growth pattern and shape changes over a 5-year follow-up period.
Main Methods:
- A 5-year follow-up study involving 29 Swiss children (8-10 months at surgery) with sagittal craniosynostosis.
- Standardized anthropometric measurements (head circumference, cranial length, breadth, cephalic index) were taken pre- and post-operatively at regular intervals.
- Data were converted to z scores for comparison with healthy controls.
Main Results:
- All patients demonstrated immediate improvement in cranial vault shape post-surgery.
- Significant long-term differences in cranial growth patterns were observed.
- A tendency towards dolichocephalic skull growth was noted, but deemed clinically irrelevant.
Conclusions:
- Total cranial vault remodeling effectively corrects sagittal craniosynostosis shape in the short term.
- While long-term growth patterns show some deviation, they are clinically insignificant, supporting the procedure's efficacy.
Abstract:
Various techniques for the correction of sagittal craniosynostosis have been described in the literature. Nevertheless, there is a lack of consensus regarding surgical procedure and timing, although a long-term anthropometric analysis may shed light on this controversy. The aim of the current study was to collect serial anthropometric data of children before and after total cranial vault remodeling and to evaluate cranial vault growth pattern. Twenty-nine Swiss children with a surgical age between 8 and 10 months were included in this 5-year follow-up. Anthropologic data of sex- and age-matched healthy Swiss children served as a control. A standardized time protocol (before, after, 6 wk after surgery, 6 mo after surgery, and then annually until the age of six) for anthropometric skull measurements (head circumference, cranial length, breadth, and cephalic index) was used. Data were converted into the z score for standardized intercenter comparison. Postoperatively, all patients showed a marked benefit in cranial vault shape. Significant differences in long-term cranial growth pattern could be seen and a relapse into a dolichocephal skull growth. Both observations were rated as clinically irrelevant.

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...
