概括
一个改进的Sunnybrook面部分级系统显示出高可重现性和数学有效性,用于评估单边面部的动态不对称性. 这种工具对大多数面部表情有效,有助于临床评估.
科学领域:
- 医学成像和生物力学
- 面部复苏和整形外科手术
背景情况:
- 桑尼布鲁克面部分级系统被广泛用于评估面部,尽管其有效性的已知局限性.
- 单边面部的动态面部不对称性需要客观和可重复的评估方法.
研究的目的:
- 修改和数学验证Sunnybrook面部分级系统,用于评估单边面部的动态不对称性.
- 为了比较面部不对称的客观,数学推导的测量与主观的临床等级.
主要方法:
- 一个修改后的Sunnybrook面部分级系统被开发出来,具有增强的描述参数.
- 三维视频分析和先进的几何形态测量量了16名患者和对照组的面部不对称性,在6种表情上进行了量化.
- 七名评估人员使用修改后的指数对面不对称进行了分级,并评估了观察者之间的和观察者内部的可靠性.
主要成果:
- 修改后的桑尼布鲁克指数显示了观察者之间和观察者内部的高可重复性 (r = -0.8).
- 在临床成绩和对休息的数学测量,最大微笑,唇包和眉毛升高之间发现了显著的正相关性.
- 对脸膨胀和强烈闭眼表情的相关性很差.
结论:
- 修改后的桑尼布鲁克分级指数是一种可复制和数学上有效的工具,用于评估大多数表情中的单边面部.
- 由于与客观指标的相关性较差,该系统的实用性在分级脸膨胀和强迫闭眼时有限.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
