【摘要】：解剖２０３例喉上神经内、外支．并对喉上神经的内、外支与舌骨大角平面、甲状腺上动脉、甲状腺侧叶上极、入喉处与甲状软骨上缘的距离，喉外支与喉上神经三角的关系进行了研究．喉上神经外支比内支小，，沿胸骨甲状肌和甲状腺上动脉深面，喉外支位于甲状腺上动脉内侧占８４．２％（１７１例），喉外支位于甲状腺上动脉后方占１３．７％（２８侧），穿咽下缩肌绕甲状腺下方达环甲肌并支配该肌．提出舌骨大角平面、甲状腺上动脉、甲状软骨上切迹、甲状腺侧叶上极、喉上神经三角是识别喉上神经外支的简便、可靠、实用的解剖学标志和提出手术中避免损伤喉上神经内、外支方法．
[Abstract]:The internal and external branches of the superior laryngeal nerve were dissected in 203 cases, and the distance between the internal and external branches of the superior laryngeal nerve and the greater angle plane of the hyoid bone, the superior thyroid artery, the superior pole of the lateral lobe of the thyroid gland, and the superior edge of the thyroid cartilage into the larynx. The relationship between the external laryngeal branch and the triangle of the superior laryngeal nerve was studied. The external branch of the superior laryngeal nerve was smaller than the internal branch, along the deep surface of the sternum thyroid muscle and the superior thyroid artery. The external laryngeal branch was located on the medial side of the superior thyroid artery in 171 cases. The external laryngeal branch was located behind the superior thyroid artery in 13.728 sides. The superior incisors of thyroid cartilage, the superior pole of the lateral lobe of the thyroid gland and the triangle of the superior laryngeal nerve are simple, reliable and practical anatomical markers for identifying the external branch of the superior laryngeal nerve and the method of avoiding the injury of the internal and external branches of the superior laryngeal nerve during operation is put forward.
