3D stereophotogrammetric analysis of operative effects after broad median craniectomy in premature sagittal craniosynostosis.

ABSTRACT

INTRODUCTION: There is ongoing discussion on the diagnostic methods, the need of surgical treatment, and the surgical strategies for premature craniosynostosis. MATERIALS AND METHODS: This study examined the operative procedure of a standardized broad median craniectomy, active tilting of the forehead, and bitemporal greenstick fracturing in children with premature sagittal craniosynostosis. To objectively analyze the direct surgical results, we used a 3D stereophotogrammetry scanner, as previously described. RESULTS: A 3D analysis showed a significant increase in the width, cranial index (CI), head and coronal circumferences, intracranial volume, and cranial base width after surgery. Head length was the only parameter that demonstrated a significant decrease postoperatively. Asymmetry and the 30° diagonal difference showed no significant changes. CONCLUSION: 3D stereophotogrammetry is a reliable and valuable tool with no side effects. It demonstrated that the extended surgical procedure achieves good postoperative results with a reduced length and increased width and, therefore, an improved CI. Additionally, the total intracranial volume was significantly increased after surgery.
