The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

科学领域:

  • 人体解剖学 解剖学 解剖学
  • 医疗成像医学成像
  • 儿科 儿科 儿科

背景情况:

  • 状腺骨异常可能会损害口功能,如食,吞和呼吸.
  • 有限的研究存在于罗宾序列 (RS) 中的状骨解剖异常.
  • 之前的观察表明RS患者的状腺较少矿化和体积较小.

研究的目的:

  • 为了比较正常的状骨形态与被诊断为孤立罗宾序列的儿童的形态.
  • 量化描述RS患者和对照人群之间的状骨形状差异.

主要方法:

  • 从RS儿童和未受影响的对照儿童的CT扫描中生成了状骨的三维 (3D) 重建.
  • 使用主要组件分析 (PCA) 创建了状骨形状的3D形态模型.
  • 部分最小正方形 - 区分分析 (PLS-DA) 和MANOVA被用来分析和比较状体形状变化.

主要成果:

  • 这项研究分析了23名RS儿童和46名年龄相匹配的对照.
  • 与对照组相比,RS组中状骨的体积较小,大角的横向分歧较大 (MANOVA,p<0.001).
  • 从PLS-DA模型中发现的第一个形状变量与观察到的群体间差异 (斯皮尔曼R=-0.56,p<0.001) 之间存在显著的相关性.

结论:

  • 3D形态模型提供了一个详细的,定量描述正常的舌骨形态.
  • 这些模型有效地检测出孤立RS患者和对照患者之间状骨的显著形态差异.
  • 这些发现强调了与罗宾序列相关的明显的舌骨变异.
