摘要
目的探讨喉返神经解剖学特征在食管癌根治手术中的应用意义。方法选取40具福尔马林固定的成人尸体标本,解剖并暴露双侧喉返神经及其相关分支,观测其走行、各部分横径以及与解剖标志的距离。结果喉返神经在气管食管沟内走行方式变异较大,主要有垂直上行(56.25%)和外下向内上斜行(38.75%);左右两侧走行方式差异有统计学意义(P<0.01)。40例共80侧喉返神经解剖结果显示,喉返神经呈树枝状68侧(85.0%),12侧(15.0%)喉返神经的分支与分支或分支与交感神经间存在吻合呈袢状。左侧喉返神经起点处横径较右侧粗(P<0.05),喉返神经各部与周围毗邻解剖标志的距离各不相同。结论食管癌根治术中喉返神经损伤是最常见的并发症,喉返神经解剖变异复杂,了解其解剖学特点在食管癌根治术中具有重要的临床意义。
Objective To explore the laryngeal neuroanatomy application significance in radical operation of esophageal cancer.Methods 40formalin-fixed adult cadavers were dissected.The laryngeal nerve and its related branches were exposed.Their courses,each part diameter and distance recurrent laryngeal nerve ministries to adjacent anatomical landmarks were observed.Results RLN in the tracheoesophageal groove traveling way varied greatly,vertical upward（56.25%）and on the outer lower inward oblique（38.75%）.Traveling way of left and right sides were significantly different（P〈0.01）.it showed that 68cases（85.0%）RL were dendritic and 12cases（15.0%）was loop shape.The diameter at the start of left side RLN was diameter than the right side（P〈0.05）,the distance around the RLN and adjacent anatomical landmarks ministries was different.Conclusion Recurrent laryngeal nerve injury is the most common complication in the treatment of esophageal carcinoma.the anatomical variations of RLN is complicated.It is important to understand its anatomy.
