本研究旨在阐明膈神经的行程及其与颈部解剖标志的相关性。我们检查了17具尸体（30侧）。在每一个中，膈神经从颈部的外侧解剖，并确定其在乳突和锁骨的胸骨和肩峰端形成的三角形内的位置。膈神经在后三角的起始点与颈丛皮肤白变在胸锁乳突肌后缘中部的起始点相似。在锁骨上三角，膈神经在Erb点附近穿过前斜角肌的前缘，其中浅点在锁骨和胸锁乳突肌后缘的上级2-3 cm处。膈神经起于后三角近神经点处，然后下行至锁骨上三角内的前斜角肌前表面。在颈淋巴清扫术中，有必要注意Erb点下方的锁骨上三角。
The present study sought to clarify the course of the phrenic nerve and its correlation with anatomical landmarks in the neck region. We examined 17 cadavers (30 sides). In each, the phrenic nerves was dissected from the lateral side of the neck, and its position within the triangle formed by the mastoid process and sternal and acromial ends of the clavicle was determined. The point where the phrenic nerve arises in the posterior triangle was found to be similar to the point where the cutaneous blanches of the cervical plexus emerge at the middle of the posterior border of the sternocleidomastoid muscle. In the supraclavian triangle, the phrenic nerve crosses the anterior border of the anterior scalene muscle near Erb’s point where the superficial point is 2-3 cm superior from the clavicle and posterior border of the sternocleidomastoid muscle. The phrenic nerve arises in the posterior triangle near the nerve point, then descends to the anterior surface of the anterior scalene muscle in the supraclavian triangle. It is necessary to be aware of the supraclavian triangle below Erb’s point during neck dissection procedures.
