这项研究建立了高加索儿童的规范性轨道生长数据,揭示了加速发育的关键时期. 了解这些模式对于识别面异常至关重要.
科学领域:
- 头骨面部的发展
- 儿科放射学 儿科放射学
- 人类测量学 人类测量学.
背景情况:
- 轨道生长对于面发育至关重要,异常常常会影响这个过程.
- 建立规范性轨道生长数据对于区分正常与病态发育至关重要.
- 有限的规范性数据存在于高加索儿科人口.
研究的目的:
- 在健康的高加索儿童群体中确定轨道间距离.
- 为儿童的轨道测量提供规范性数据.
主要方法:
- 追溯分析了466个来自高加索3个月至10岁儿童的面CT扫描.
- 测量包括神经眼平面的骨内间轨道距离 (IOD) 和骨侧轨道距离 (LOD).
- 使用曼-惠特尼测试进行统计分析,以比较年龄和性别群体.
主要成果:
- 平均IOD从3个月的18.76毫米增加到10年后的22.79毫米.
- IOD和LOD的显著增加发生在前两年,并在7-8岁之间.
- IOD/LOD比率保持不变,这表明轨道成长具有同度性.
结论:
- 该研究为高加索儿童提供了基本的规范性轨道测量数据.
- 确定了两个加速轨道生长的关键时期.
- 这些数据有助于对面发育和潜在异常的临床评估.

Midrange
Simply put, the midrange is half of the data set’s range. Similar to the mean, the midrange is sensitive to the extreme values and hence the prospective outliers. However, unlike the mean, the midrange is not sensitive to all the values of the data set that lie in the middle. Thus, it is prone to outliers and...
Range Rule of Thumb to Interpret Standard Deviation
For instance, the range rule of thumb can be used to find the tallest and the shortest student in a class, given the mean student height and standard deviation. If the mean student height is 1.6 m and the standard deviation, s is 0.05 m, the height of...
