The pharyngeal plexus is an essential anatomical structure, but the contributions from the glossopharyngeal and vagus nerves and the superior cervical ganglion that give rise to the pharyngeal plexus are not fully understood. The pharyngeal plexus is likely to be encountered during various anterior cervical surgical procedures of the neck such as anterior cervical discectomy and fusion. Therefore, a detailed understanding of its anatomy is essential for the surgeon who operates in and around this region. Although the pharyngeal plexus is an anatomical structure that is widely mentioned in literature and anatomy books, detailed descriptions of its structural nuances are scarce; therefore, we provide a comprehensive review that encompasses all the available data from this critical structure. We conducted a narrative review of the current literature using databases like PubMed, Embase, Ovid, and Cochrane. Information was gathered regarding the pharyngeal plexus to improve our understanding of its anatomy to elucidate its involvement in postoperative spine surgery complications such as dysphagia. The neural contributions of the cranial nerves IX, X, and superior sympathetic ganglion intertwine to form the pharyngeal plexus that can be injured during ACDF procedures. Factors like surgical retraction time, postoperative hematoma, surgical hardware materials, and profiles and smoking are related to postoperative dysphagia onset. Thorough anatomical knowledge and lateral approaches to ACDF are the best preventing measures.

咽丛：解剖学回顾，以更好地了解术后吞咽困难。

咽丛是必不可少的解剖结构，但舌咽和迷走神经以及上颈神经节引起咽丛的贡献尚不完全清楚。在各种颈椎前路颈椎前路手术和融合术中，可能会遇到咽丛。因此，对于在该区域及其周围进行手术的外科医生，对其解剖结构的详细了解至关重要。尽管咽丛是一种在解剖学和解剖学书籍中被广泛提及的解剖结构，但对其结构细微差别的详细描述却很少。因此，我们提供了涵盖该关键结构中所有可用数据的全面评估。我们使用PubMed，Embase，Ovid和Cochrane等数据库对当前文献进行了叙述性回顾。收集了有关咽丛的信息，以增进我们对咽丛的解剖的了解，以阐明其参与术后脊柱外科手术并发症（例如吞咽困难）的情况。颅神经IX，X和上交感神经节的神经贡献交织在一起，形成咽丛，在ACDF手术中可能会受伤。诸如手术回缩时间，术后血肿，手术硬件材料，轮廓和吸烟等因素与术后吞咽困难发作有关。全面的解剖知识和ACDF的侧入法是最好的预防措施。收集了有关咽丛的信息，以增进我们对咽丛的解剖的了解，以阐明其参与术后脊柱外科手术并发症（例如吞咽困难）的情况。颅神经IX，X和上交感神经节的神经贡献交织在一起，形成咽丛，在ACDF手术中可能会受伤。诸如手术回缩时间，术后血肿，手术硬件材料，轮廓和吸烟等因素与术后吞咽困难发作有关。全面的解剖知识和ACDF的侧入法是最好的预防措施。收集了有关咽丛的信息，以增进我们对咽丛的解剖的了解，以阐明其参与术后脊柱外科手术并发症（例如吞咽困难）的情况。颅神经IX，X和上交感神经节的神经贡献交织在一起，形成咽丛，在ACDF手术中可能会受伤。诸如手术回缩时间，术后血肿，手术硬件材料，轮廓和吸烟等因素与术后吞咽困难发作有关。全面的解剖知识和ACDF的侧入法是最好的预防措施。交感神经节和上交感神经节交织在一起，形成咽丛，在ACDF手术中可能会受伤。诸如手术回缩时间，术后血肿，手术硬件材料，轮廓和吸烟等因素与术后吞咽困难发作有关。全面的解剖知识和ACDF的侧入法是最好的预防措施。交感神经节和上交感神经节交织在一起，形成咽丛，在ACDF手术中可能会受伤。诸如手术回缩时间，术后血肿，手术硬件材料，轮廓和吸烟等因素与术后吞咽困难发作有关。全面的解剖知识和ACDF的侧入法是最好的预防措施。
