3-Dimensional CT for preoperative measurement and postoperative assessment in craniosynostosis / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the significance of 3-dimensional (3-D) CT for preoperative measurement and postoperative assessment in craniosynostosis.</p><p><b>METHODS</b>17 cases with craniosynostosis underwent 3-D CT reconstruction. The 3-D images were used to perform cephalometry. The cases included brachycephalic, caphocephalia, plagiocephaly. The CVAI must be measured for plagiocephaly. Measurement results were compared before and after operation in 9 cases.</p><p><b>RESULTS</b>The bone segments were advanced 1.5 - 3 cm in brachycephalic, retruded 2 - 4 cm in scaphocephalic, moved back and forth about 2 cm in plagiocephaly.</p><p><b>CONCLUSIONS</b>Preoperative 3-D CT reconstruction and measurement can be used to design the advancement distance of bone flap and orbito-frontal bone bridge, as well as to estimate the treatment results before operation.</p>
