颈部臂丛神经入路的解剖学研究

目的研究颈部臂丛神经入路的解剖特点,探讨臂丛神经的显露方法,使其显露更加简便、安全和充分。方法取甲醛溶液固定的成人尸体标本21具,解剖观察颈筋膜浅层与颈神经浅丛的位置关系,解剖观察颈后三角颈筋膜浅、深层之间的脂肪层的结构、内容,颈筋膜深层的质地及其与臂丛神经的解剖关系。取甲醛溶液固定的成人尸体标本21具,制成颈部连续断层标本,观察不同断面颈后三角颈筋膜浅层深面蜂窝组织的边界、内容、与臂丛神经的解剖关系。结果在颈中部及其以下,颈后三角的颈筋膜浅、深两层之间的脂肪层界限清晰完整,其内无重要结构,颈筋膜深层质地致密,臂丛神经紧位于其深面。结论利用颈筋膜与臂丛神经解剖关系,可使颈部臂丛神经的显露更简便、安全。

Anatomical Exploration with Respect to the Exposition of Brachial Plexus in Neck Area

Objective To investigate the anatomic features in the approach to the brachial plexus in neck,make the exposure of brachial plexus more convenient and safer.Methods Necks of twenty-one embalmed adult cadavers were dissected to observe the location relationship between superficial layer of cervical fascia and superficial cervical plexus,the structure of the fat layer between the superficial layer and deep layer of cervical fascia,and the texture of deep layer of cervical fascia and the location relationship ...
