Intraoperative facial nerve monitoring is performed by electromyographic recording of motor action potentials generated by facial nerve stimulation or mechanical damage of the facial nerve, and helps the surgeon to localize the course of this nerve, reduce the possibility of its injury during surgery, and assure its anatomical and functional integrity. We report our experience on the intraoperative facial nerve monitoring in 35 patients, ten of which belong to absolute indications for monitoring, and to relative indications the remaining cases. In every case, we used the Nerve Integrity Monitor (NIM-2), manufactured by Xomed. Assessment of facial nerve integrity degree is performed pre- and postoperatively using the House-Brackmann classification. We only found in two cases (5.7%) some degree of palsy in the late postoperative period. No correlation was found between the recorded intraoperative response and the functional results in the early postoperative period.
术中面神经监测通过对面神经刺激或面神经机械损伤所产生的运动动作电位进行肌电图记录来完成,有助于外科医生确定该神经的走行,降低手术期间其损伤的可能性,并确保其解剖和功能完整性。我们报告了35例患者术中面神经监测的经验,其中10例属于监测的绝对适应证,其余病例属于相对适应证。在每例患者中,我们使用了由Xomed公司生产的神经完整性监测仪(NIM-2)。使用House-Brackmann分级在术前和术后对面神经完整性程度进行评估。我们仅在2例(5.7%)患者中发现术后晚期有一定程度的面瘫。术后早期记录的术中反应与功能结果之间未发现相关性。
