[目的]揭示颈筋膜与臂丛神经的解剖关系,增进臂丛神经显露的安全和简捷。[方法]取福尔马林处理的成人尸体标本21具,解剖观察颈筋膜浅层与颈神经浅丛的位置关系,解剖观察颈筋膜浅层、深层之间的脂肪层的结构,颈筋膜深层的质地及其与臂丛神经的解剖关系。[结果]在颈中部及其以下的颈筋膜浅、深两层之间的脂肪层中无颈神经浅支,在此脂肪层中除颈横动脉和肩胛舌骨肌无重要结构,颈筋膜深层质地致密,臂丛神经紧位于其深面。[结论]利用颈筋膜深层紧位于臂丛神经浅面、致密清晰,其浅面脂肪内无重要结构的特点,可使颈部臂丛神经的显露更简捷、安全。
[Objective] To reveal the anatomic relationship between cervical fascia and brachial plexus and to improve the safety and simplicity of the brachial plexus. [Methods] The 21 adult adult cadavers treated with formalin were dissected to observe the relationship between the superficial cervical fascia and the superficial cervical nerve. The structure of the fatty layer between the superficial and inferior cervical fascia was dissected. Deep fascia texture and its anatomic relationship with brachial plexus. [Result] There was no superficial branch of cervical nerve in the fat layer between the superficial and deep cervical fascia in the middle of the neck and below. In this fat layer, there was no important structure except the transverse carotid artery and the scapular hyoid muscle. Deep membrane dense texture, brachial plexus in its deep surface. [Conclusion] The deep cervical fascia is located in the superficial surface of the brachial plexus, dense and clear, and has no important structure in the superficial fat. It can make the exposed cervical brachial plexus nerve more simple and safe.
