A technique is described for intraoperative electrophysiologic monitoring of laryngeal muscles. This technique has been used to identify the laryngeal nerves during surgery for recurrent tumors of the thyroid gland, when direct visualization of the nerves is difficult or impossible. Laryngeal muscle electrical activity is monitored with endoscopically placed wire-hook electrodes inserted into the vocal folds bilaterally. Neurotonic discharges are detected when the recurrent laryngeal nerves are manipulated during surgical dissection. Precise localization of the recurrent nerves is possible using a hand-held bipolar stimulator.
本文描述了一种用于术中喉肌电生理监测的技术。该技术已被用于在甲状腺复发性肿瘤手术中难以或无法直接观察到神经时识别喉神经。通过双侧经内镜插入声带的线钩电极监测喉肌电活动。在手术解剖过程中操作喉返神经时可检测到神经紧张性放电。使用手持双极刺激器可实现喉返神经的精确定位。
