概括
在神经外科手术期间切断的自由边缘 (FET) 对神经构成风险. 这项研究确定了FET切割的安全区域,以最大限度地减少三角膜神经 (CN IV) 和眼运动神经 (CN III) 的损伤.
科学领域:
- 神经外科 神经外科
- 神经解剖学是一个神经解剖学.
- 手术解剖学手术解剖学
背景情况:
- 的自由边缘 (FET) 可能需要切割特定的神经外科方法,包括洞穴鼻和动脉瘤.
- 没有先前的解剖学研究准确地定义了三角膜神经 (CN IV),眼运动神经 (CN III) 和FET之间的关系,以建立安全的手术走廊.
研究的目的:
- 在解剖学上研究三角膜神经 (CN IV),眼运动神经 (CN III) 和的自由边缘 (FET) 之间的关系.
- 在神经外科手术过程中确定FET切割的安全区域,以最大限度地降低神经损伤的风险.
主要方法:
- 使用数字微刻度器对十个装的人体标本 (20个侧面) 进行形态测量分析.
- 测量包括三角膜神经 (TP) 和眼运动孔 (OP) 之间的距离,CN IV的入腔段和无神经的FET.
- 此外,还测量了沿CN III从OP到CN III/CN IV交叉点的距离以及耳角.
主要成果:
- 三角膜神经 (CN IV) 始终被发现在FET的深层.
- 在55%的病例中观察到FET的无神经段 (<2毫米),其中20%小于1毫米.
- 从眼运动孔 (OP) 到CN III/CN IV交叉点的平均距离为10.17毫米.
结论:
- 这项研究证实了三神经 (CN IV) 的入口腔段的存在.
- 切割FET带有最小的CN IV损伤风险,当切割距离眼运动孔 (OP) 后面不到2毫米或超过10毫米时.
- 另一种选择是,在FET的交叉点后面的截面和石脊的虚拟延伸也被认为是一个更安全的选择.

Body Planes
Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
