摘　　要：目的探讨实时监测技术对预防喉返神经损伤的意义及应用价值。方法对55例再次甲状腺手术患者在全麻手术中使用喉返神经探测仪进行实时喉返神经监测(IONM),术中分离显露喉返神经,并以神经刺激探针探测证实喉返神经在甲状腺后段行程及功能状态以保护其免受损伤,评估患者术后喉返神经损伤和声带功能恢复情况。结果共探测喉返神经107条,均成功显露。4例术前已证实有单侧声带麻痹的患者,术中探查该侧喉返神经证实3例被离断,另有1例被结扎,经松解后喉返神经肌电信号恢复,术后声带功能恢复。2例(3.64%)完整显露喉返神经的病例,手术结束前肌电信号消失,术后出现暂时性声带麻痹,均于2个月内恢复。结论使用喉返神经探测仪利于显露和保护喉返神经,有助于发现导致喉返神经损伤的原因并能较好地预测术后声带功能恢复的情况,减少医源性喉返神经损伤发生率,值得在再次甲状腺手术中推广。： Objective To assess the usage and value of monitoring the recurrent laryngeal nerve（RLN） during thyroid surgery by real-time laryngeal electromyography. Methods Fifty-five patients were under general anesthesia and thyroid reoperation. NIM-ResponseTM electromyographic （EMG） monitor system was used for assistance of dissection, exposure and protection of the RLN during the surgical procedures. Results There were 107 RLNs exposed during the surgeries in all 55 patients. The unilateral RLN injured in 4 patients were also explored, among them 3 injuries were caused by transection, and 1 by ligation, which was detected precisely and released, the EMG recovered intraoperation and the vocal cord function recovered postoperation. The EMG of two successfully revealed RLN disappeared during surgical procedures, temporary vocal cord paralysis occurred and recovered in two months, the temporary palsy rate was 3.64%（2/55）. Conclusions EMG monitor system is sensitive and accurate for explosing and preserving the RLN during thyroid reoperation. It is valuable for detecting the injury causes of RLN and predicting the postoperative function of vocal cord. This system deserves general utilization for thyroid surgery, especially for reoperation.
