颈前部手术的应用解剖及临床意义

目的:为颈前部手术提供相关血管、神经的形态学依据。方法:在16具(32侧)成人头颈部标本上解剖观测颈前部血管和神经的走行及分布。结果:甲状腺左叶平均长度为(49.5±8.2)mm,右叶平均长度为(50.1±7.8)mm,有锥形叶者7例,占44%;16例中有1例甲状腺最下动脉,甲状腺最下动脉出现率为6%;甲状腺上动脉与喉上神经伴行,甲状腺下动脉与喉返神经相交叉。喉上动脉入喉处在甲状软骨上角的前下方左侧为(13.91±2.83)mm,右侧为(14.96±2.56)mm,两侧比较差异有统计学意义(t=2.985,P<0.01);喉上神经喉内支入喉处在甲状软骨上角前下方左侧为(11.80±3.42)mm,右侧为(12.24±2.68)mm;喉下神经在甲状软骨下角后下方入喉,距离甲状软骨下角左侧(5.38±1.56)mm,右侧(5.69±1.77)mm,两侧差异有统计学意义(t=2.438,P<0.05)。结论:本研究对颈前部手术有一定临床参考意义。
