Purpose:
While previous studies have focused on qualitative assessments of surgical outcomes, limited research exists on quantitative analysis of intracranial and intraorbital volume changes following surgical correction. This study assesses preoperative and postoperative changes in intracranial and intraorbital volumes in children undergoing craniosynostosis correction surgery.
Methods:
A retrospective observational imaging study analyzed CT scans of 103 children who underwent craniosynostosis surgery between January 2009 and June 2022. Of these, 44 patients had both preoperative and postoperative CT scans suitable for volumetric assessment. Volumetric analysis was conducted using the Brainlab Elements Planning software, measuring intracranial and intraorbital volumes.
Results:
In patients who underwent cranial vault remodeling with orbital advancement, there was a significant increase in intracranial volume (3.85%) and bilateral orbital volumes (right: 8.74%, left: 7.31%; p < 0.001).
Conclusion:
A quantitative volumetric analysis demonstrated significant improvements in both intracranial and orbital volumes following craniosynostosis surgery with orbital advancement.
