PURPOSE
To evaluate the development of the sphenooccipital sychondrosis as seen on high-resolution thin-section CT scans.
METHODS
We retrospectively reviewed the records of 253 patients, ages 1 to 77 years old, who had had thin-section CT examination of the skull base.
RESULTS
An ossification center appeared midline in the patients who were 8 to 13 years old. Six of 12 girls showed additional symmetric ossification centers on either side of the midline; however, this pattern was not seen in boys. No sphenooccipital synchondrosis persisted in any patient past the age of 13 years.
CONCLUSION
High-resolution CT scans of the skull base can show a pattern of progressive ossification of the sphenooccipital synchondrosis, which can be readily recognized and predicted.
目的
评估在高分辨率薄层CT扫描上观察到的蝶枕软骨结合的发育情况。
方法
我们回顾性分析了253例年龄在1至77岁之间接受过颅底薄层CT检查患者的记录。
结果
在8至13岁的患者中，一个骨化中心出现在中线位置。12名女孩中有6名在中线两侧出现了额外的对称骨化中心；然而，男孩中未观察到这种模式。13岁以后的任何患者中均未发现蝶枕软骨结合持续存在。
结论
颅底的高分辨率CT扫描可以显示蝶枕软骨结合的渐进性骨化模式，这种模式易于识别和预测。
