Objective To study the anatomical relationship between the recurrent laryngeal nerve ( RLN) and the inferior thyroid artery, to investigate the prophylactic measures on how to avoid iatrogenic injures while exposing the RLN during thyroid operation. 目的观察喉返神经与甲状腺下动脉的关系,探讨避免因显露而造成喉返神经医源性损伤的预防措施。
It is observed that abnormal passage of the right recurrent laryngeal nerve caused, by the retro-esophageal right subclavian artery is 1%. 由于右锁骨下动脉食管后位而引起的右喉返神经经过异常者占1%。
It was found that in 1 side of a larynx the superior laryngeal artery came from superior thyroid artery and divided into 2 branches before going into laryngeal cavity. 有1具右侧喉上动脉起源于甲状腺上动脉后,在入喉前分为2支入喉。
