Abstract

PURPOSE

The formation of pterygoalar (Pa) and pterygospinous (Ps) bars are controversial whether they are secondary ossifications with aging or phylogenetic remnant. Therefore we aimed to evaluate the presence of Pa and Ps bars in children on routine cranial computed tomography images.

METHODS

We retrospectively analyzed the cranial computed tomography images of 500 children under the age of 18. Besides the 0.5 mm axial images, maximum intensity projection and 3D reconstructions were also used. The existence of incomplete or complete Pa and Ps bars were investigated.

RESULTS

Incomplete and complete Pa bar was detected in 4.6% and 2.2% of the cases, respectively. Incomplete Ps bar was seen in 13.6% of the cases and complete was in 6%. In total, per 1000 sides, 12 (2.4%) complete and 27 (5.4%) incomplete Pa bars were detected. In the same way, 35 (7%) complete and 88 (17.6%) incomplete Ps bars were seen. The smallest age ossification detected was 5 months old. Additionally, the prevalence of Pa and Ps bars between the under and over 10 years old age groups were statistically significant. Aging increased the prevalence.

CONCLUSION

Considering our results, it seems that the ossification of Pa and Ps ligaments may not be solely related with aging.

摘要

目的

翼腭（Pa）和翼棘（Ps）弓的形成是有争议的，它们是随着年龄增长而形成的二次骨化，还是系统发生的残余物。因此，我们旨在评估在常规头颅 CT 图像中儿童是否存在 Pa 和 Ps 弓。

方法

我们回顾性分析了 500 名年龄在 18 岁以下的儿童的头颅 CT 图像。除了 0.5mm 轴位图像外，还使用了最大密度投影和 3D 重建。研究了不完全或完全 Pa 和 Ps 弓的存在情况。

结果

不完全和完全 Pa 弓分别在 4.6%和 2.2%的病例中检测到。不完全 Ps 弓在 13.6%的病例中可见，完全 Ps 弓在 6%的病例中可见。总的来说，每 1000 例中有 12 例（2.4%）完全和 27 例（5.4%）不完全 Pa 弓。同样，有 35 例（7%）完全和 88 例（17.6%）不完全 Ps 弓。检测到的最小年龄骨化是 5 个月大。此外，10 岁以下和 10 岁以上年龄组 Pa 和 Ps 弓的患病率有统计学意义。随着年龄的增长，患病率增加。
