To determine the clinical evaluation role of laryngeal electromyography (LEMG) and laryngeal somatosensory evoked potential (LSEP) in the recurrent laryngeal nerve paralysis by anterior elective cervical surgery.
LEMG and LSEP were determined in 18 patients with recurrent laryngeal nerve paralysis by anterior elective cervical surgery at the 1st, 2nd and 4th week after operation. The comparison between the normal control (18 health adults) and the results of LEMG and LSEP were analyzed.
The latency prolonged and the amplitude decreased of LSEP in all patients as compared with the control group. Furthermore, reinneration potential increased gradually in all patients at the 1st, 2nd and 4th week after operation (P<0.05). The results of LEMG showed increase of denervation potential. The higher the amplitude of LSEP and LEMG, the better the prognosis of the recurrent laryngeal nerve paralysis.
LEMG and LSEP might evaluate regenerate the degree of recurrent laryngeal nerve injury caused by anterior elective cervical surgery and predict the prognosis of the recurrent laryngeal nerve paralysis.
探讨喉肌电图（LEMG）及喉体感诱发电位（LSEP）在择期颈前路手术致喉返神经麻痹中的临床评估作用。
对18例择期颈前路手术致喉返神经麻痹患者分别于术后第1、2、4周行LEMG及LSEP检测，并分析其与18例健康成人正常对照结果的差异。
与对照组相比，所有患者LSEP潜伏期延长、波幅降低。此外，术后第1、2、4周所有患者的再支配电位逐渐升高（P<0.05）。LEMG结果显示失神经电位增加。LSEP和LEMG波幅越高，喉返神经麻痹预后越好。
LEMG及LSEP可评估择期颈前路手术致喉返神经损伤的再生程度，并预测喉返神经麻痹的预后。
