概括
这项研究表明,双边面显微症 (CFM) 主要涉及向后倾斜的下巴线和明显的下巴衰退. 在CFM患者的面部不对称性往往偏向更严重的受影响侧面.
科学领域:
- 面外科手术 面外科手术
- 儿科牙科 儿科牙科
- 医学成像医学成像
背景情况:
- 面显微症 (CFM) 是一种常见的先天性异常,但由于面部不对称,双边病例的评估具有挑战性.
- 传统的脑膜测量在准确测量双边CFM中的不对称性方面存在局限性.
- 三维 (3D) 头脑测量分析提供了一种更精确的方法来表征面形态.
研究的目的:
- 描述双边CFM儿童的面形态.
- 使用3D头脑测量分析进行双边CFM中面部结构的详细评估.
- 确定与双边CFM相关的关键形态特征.
主要方法:
- 对8名双边CFM患者和10名对照人群进行了回顾性3D头脑测量分析.
- 建立了一个使用法兰克福水平平面 (FHP),中平面 (MSP) 和Nasion垂直平面 (CP) 的坐标系统.
- 评估了大,下,下巴和闭口参数,使用15个线性和角度测量;根据Pruzansky-Kaban分类分层分组.
主要成果:
- 双边CFM患者表现出小腿骨高度和下体长度减少 (p < 0.001).
- 观察到一个明显的后后倾斜的闭合平面 (p < 0.001) 和明显的下巴回退 (p < 0.001).
- 发现了显著的侧面下巴偏差 (p < 0.05),以及下巴位置,闭合平面和下尺寸之间的相关性.
结论:
- 双边CFM的特点是后侧倾斜的闭合平面和显著的下逆转.
- 面部不对称性,包括闭合平面和下巴偏差,始终有利于更受影响的侧面.
- 两侧轻微的下干扰导致面部不对称性不那么严重.

01:27Cranial Bones: Lateral View
2.6K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
7.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
