Since the introduction of transcutaneous-transcricoidal needle approaches, electromyography (EMG) of the posterior cricoarytenoid muscle (PCA) became easier to perform and teach. Among the Neurolaryngology working group of the European Laryngological Society, several centers have adopted PCA EMG as part of their routine EMG workup in vocal fold immobility collectively gathering long-term experience. The purpose is to give an update and an extension to already existing guidelines on laryngeal EMG with specific regard to PCA EMG.
Consensus of all co-authors is based on continuous exchange of ideas and on joint laryngeal EMG workshop experiences over at least 7 years. A Delphi method of consensus development was used, i.e., the manuscript was circulated among the co-authors until full agreement was achieved.
Step-by-step instructions on how to perform and interpret PCA EMG are provided.
Further research should include the establishment of normal values for PCA and thyroarytenoid muscle (TA) EMG as well as studies on the nature of some unusual activation pattern commonly seen in chronically lesioned PCA.
自从引入经皮经声门针技术以来，后环杓肌（PCA）的肌电图（EMG）变得更容易进行和教学。在欧洲喉科学会的神经喉科工作组中，有几个中心已经将 PCA EMG 作为其声带固定性常规 EMG 检查的一部分，共同积累了长期的经验。目的是更新和扩展已经存在的关于喉肌电图的指南，特别是关于 PCA EMG 的指南。
所有共同作者的共识是基于不断的思想交流和至少 7 年的联合喉肌电图研讨会经验。采用德尔菲共识发展方法，即手稿在共同作者之间传阅，直到达成完全一致。
提供了关于如何进行和解释 PCA EMG 的逐步说明。
进一步的研究应包括建立 PCA 和甲状旁腺肌（TA）EMG 的正常值，以及对一些在慢性损伤的 PCA 中常见的不寻常激活模式的性质的研究。
