摘要
为甲状腺手术中结扎甲状腺上动脉时防止喉上神经损伤提供形态学依据 ,对 86例甲状腺上动脉和喉上神经的发出、走行、分支、分布和两者的伴行关系进行了解剖观测 ,结果发现 ,(1)甲状腺上动脉 84 88%起自颈外动脉 ,起始处外径为 2 2± 0 8(1 1~ 3 4)mm ,起始点至甲状腺上极的长度为 (3 1± 1 3)cm .(2 )喉上神经均起自迷走神经下神经节 ,起始处横径为 (2 0± 0 4)mm ,在舌骨大角处分为内支和外支 ,外支在甲状腺上极上方 (0 9± 0 4)cm处与甲状腺上动脉分离 .(3)在上、中段甲状腺上动脉与喉上神经密切伴行 ,在下段上部分离 ,喉上神经外支入环甲肌点在平甲状腺上极处相距 (7± 3)mm .可见 ,施甲状腺手术结扎甲状腺上动脉宜在甲状腺侧叶上极或在甲状腺实质内进行 。
In order to offer a morphological basis for preventing any injury to laryngeal nerve during the ligation on thyroid artery in thyroid operation,the origin,way,branch,distribution and their accompanying relationship between thyroid artery and laryngeal nerve were anatomical observed.The result showed that(1)the 84.88% of thyroid artery started from extemal carotid artery diameter of begining part was 2 2±0 8(1 1~3 4)mm,its lenth from starting part to thyroid was (3 1±1 3)cm.(2)the laryngeal nerve started from lower ganglion inferius and its diameter of starting part was(2 0±0 4)mm.Its internal and external branch separated at the plaes of greater horn of hyoid bone and its external branch separated from thyroid artery at the part of (0 9±0 4)cm from the pole of thyroid.(3)In the above and middle part of thyroid,the thyroid artaery was close concomitant to the laryngeal nerve and separated at its lower part.The inserting part of laryngeal nerve to cricothyroid muscle was at the point of (7±3) mm from the pole of the thyroid.
