概括
在IIA型面显微症 (CFM) 中,体单元表现出不充分的生长,是主要的下变形中心. 受影响的半下在生长过程中也会在后面旋转.
科学领域:
- 头骨面部的发展
- 儿科的整形手术.
- 骨生物学 骨生物学
背景情况:
- 面显微症 (CFM) 在下生长中提出了复杂的挑战.
- 了解IIA型CFM下部的自然发育对于治疗计划至关重要.
研究的目的:
- 分析IIA型CFM儿童下结构和自然生长.
- 用功能单元分析识别下变形的主要部位.
主要方法:
- 分析了8名未经手术的儿童的CT数据,这些儿童患有单边IIA型CFM.
- 功能单位分析评估了尺寸差异,年增长和角度测量.
- 数据涵盖了26年的生长间隔.
主要成果:
- 在受影响的侧面,心状,冠状和身体单位较小 (63%,79%,90%).
- 带状单元的生长显著放缓 (大约1. 60%的未受影响的一面).
- 受影响的身体单元的向后旋转角度在研究期间增加.
结论:
- 冠状体单位被确定为IIA型CFM的中下变形.
- 不够的状体生长和后半旋转有助于空间差异.

01:22Sutures of the Skull
6.4K
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...

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...
