临床常用肌瓣肌内神经分布的研究

Distribution of the intramuscular nerves of commonly used muscle flaps

目的:研究临床常用肌瓣的肌内神经走行及分布,为临床提供解剖学基础。方法:在5具新鲜成人尸体标本上,完整取下展肌、背阔肌、股薄肌、腹直肌、胸小肌以及缝匠肌,观察测量肌外神经来源,并采用改良Sihler’s肌内神经染色法观察肌内神经的分支分布。结果:经Sihler’s染色后的肌肉标本,大体形态保持完整,呈透明或半透明、淡蓝色,肌内神经分支被染成蓝紫色,其在肌肉内的分布及走行清晰可见。结论:(1)根据染色结果可将肌肉分为不同的肌亚部;(2)结果对临床外科手术具有重要的指导意义。

Objective： To study the distribution of the intramuscular nerves of commonly used muscle flaps, and provide anatomic basis for clinic application. Methods： Abductor hallucis, latissimus dorsi, gracilis, rectus abdominis, pectoralis minor and sartorius were removed completely from 5 fresh adult cadavers. The origins of extra-muscular nerves of every muscle were followed, and then, the course and distribution of intramuscular nerves were studied by modified Sihler＇s technique. Results：Muscles treated with Sihler＇ staining kept their appearance completely, with a light blue color and transparent or semitransparent texture. The branches ofintra-muscle nerves were clearly visible in treated muscles with blue-purple color. Conclusions： （1） Subdivision of muscles can be performed under Sihler＇s staining. （2）The staining results is valuable for guiding plastic operation correctly.
