概括
这项研究在轨道爆破骨折中绘制了相对于轨下边缘 (IM) 的后边缘 (PL). 结果显示,在切片L5处,PL距离IM峰值,有助于手术规划.
科学领域:
- 眼科医生 眼科 眼科
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
背景情况:
- 后端 (PL) 在轨道床重建中对后部植入物支至关重要.
- 轨道地板爆裂骨折需要精确的解剖学理解,以进行有效的手术修复.
- 绘制PL和光孔的地图对于预防手术内并发症至关重要.
研究的目的:
- 描述一项用于绘制地图后边缘 (PL) 与轨道下边缘 (IM) 相关的技术.
- 为了确定光孔相对于PL的位置.
- 为了创建一个参考地图,帮助轨道地板重建.
主要方法:
- 分析了67个面部计算机断层扫描 (FCT) 扫描的病人与轨道床爆裂骨折.
- 利用了Osirix软件和基于冠状轨道划分为七个斜面切片 (L1-L7) 的标准化测量技术.
- 测量了PL与IM之间的距离,并确定了光学孔的位置.
主要成果:
- 在切片L5 (中位数:30.1毫米) 观察到PL与IM的距离最大.
- 距离从PL到IM的距离在中位数上升到L5,然后下降 (提供L1-L7中位数距离).
- 光孔与IM的中位距离在L7处为43.7毫米,表明其接近中位轨道底部.
结论:
- 与IM和光孔相对应的PL的参考地图被生成.
- 从IM到PL的距离遵循一个特定的模式,在L5.5达到峰值.
- 证实了光孔与中枢轨道底部的PL的接近,这对于外科计划和剖析至关重要.

01:14Cranial Bones: Superior and Posterior View
2.3K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
2.3K
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...

01:17Accessory Structures of the Eye
1.6K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
