We aimed to localize the pharyngeal branches of the pharyngeal plexus to preclude postoperative complications such as dysphagia resulting from injury to those branches. Cranial nerves IX and X and the sympathetic trunk were dissected on 10 sides in the necks of embalmed adult cadavers of European descent to identify the pharyngeal branches so that anatomical landmarks could be identified and injury thereby avoided. In all sides, the pharyngeal branches originated from the glossopharyngeal and vagus nerves and the superior cervical ganglion and entered the posterior pharyngeal wall at the C2-C4 levels within 10 mm medial to the greater horn of the hyoid bone. All pharyngeal branches were anterior to the alar fascia. Based on our anatomical study, vagus nerve branches to the pharyngeal muscles enter at the C3/C4 vertebral levels. Such knowledge might help decrease or allow surgeons to predict which patients are more likely to develop dysphagia after cervical spine surgery.
我们旨在定位咽丛的咽支，以避免因损伤这些分支而导致术后吞咽困难等并发症。我们解剖了 10 具欧洲裔防腐成人尸体的颈部的颅神经 IX 和 X 以及交感干，以识别咽支，从而确定解剖学标志并避免损伤。在所有的侧支中，咽支起源于舌咽神经和迷走神经以及颈上神经节，并在舌骨大角内侧 10mm 处 C2-C4 水平进入后咽壁。所有咽支均位于翼筋膜前方。基于我们的解剖学研究，迷走神经分支至咽肌的进入部位在 C3/C4 椎体水平。这些知识可能有助于减少或让外科医生预测哪些患者在颈椎手术后更容易发生吞咽困难。
