便携式立体摄影仪 (PSP) 显示了可接受的准确性和精确性,用于口唇裂 (CLP) 面部分析. 这项技术可以帮助为CLP患者进行3D手术规划.
科学领域:
- 面外科手术 面外科手术
- 医学成像医学成像
- 整形手术 整形手术 整形手术
背景情况:
- 立体摄影测量为整形手术规划提供了潜力.
- 在唇裂患者中需要验证立体摄影仪 (Stereophotogrammetry).
研究的目的:
- 评估便携式立体相像测量系统 (PSP) 的准确性和精度.
- 评估PSP用于面部分析,特别是在患有CLP的患者中.
主要方法:
- 横截面研究,将PSP测量与数字尺测量进行比较.
- 通过测量偏差评估的精度 (<1.0毫米非常好,1.0-2.0毫米好,2.0-3.0毫米中等,>3.0毫米不满意).
- 使用平均绝对偏差 (MAD) 和平均相对误差 (MRE) 评估精度.
主要成果:
- 精度:6/15次测量非常好,2次测量很好,3次测量中等,4次测量不满意 (Al-Al,Sti-Me,Me-C,UR1s).
- 精度:86.7%的测量结果显示出极好的MAD.
- 在53.3%的测量中,MRE表示精确度很好或很好.
结论:
- PSP在CLP患者的面部分析中表现出可接受的准确性和精度.
- 可以将PSP集成到CLP治疗的3D规划工作流程中.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
