甲状腺毗邻关系复杂。为探索与甲状腺切除手术有关的甲状腺局部解剖的特点，我们对３２例成人尸体的甲状腺毗邻关系进行了解剖观察和测量。从甲状腺的形状、大小，甲状腺上动脉与喉上神经走行关系，甲状腺下动脉与喉返神经的走行关系，甲状旁腺的形态及分布，报告了观察的结果。总结了１０点对甲状腺次全切除有启迪意义的局部解剖特点，并提出了手术的危险区、安全区、变异区和易损伤区的概念 Thyroid adjacent to the complex relationship. To explore the characteristics of thyroid gland dissection associated with thyroidectomy, we performed anatomical observations and measurements of the thyroid adjacent relationship in 32 adult cadavers. From the thyroid shape, size, the thyroid artery and the laryngeal nerve walking relationship, the thyroid artery and the recurrent laryngeal nerve relationship, the morphology and distribution of parathyroid, reported the results. This paper summarizes the enlightening local anatomic features of subtotal thyroidectomy at 10 o’clock and puts forward the concept of dangerous, safe, variant and vulnerable areas of surgery
