Intraoperative cranial motor nerve monitoring has improved the preservation of cranial nerve function during cerebellopontine angle and skull base surgery. Further improvements are needed to provide greater selectivity and sensitivity during intraoperative motor nerve stimulation. Use of bipolar stimulator probes has been recommended by previous investigators. The authors hypothesized that a coaxial bipolar stimulator design might provide important advantages over existing designs. This study compared the results of bipolar and monopolar stimulation using a coaxial stimulator probe in a rat model and during neurotologic procedures. The coaxial bipolar probe was superior in selectivity, thereby permitting useful multichannel monitoring. The coaxial design may also offer advantages over previous bipolar stimulator designs.
术中颅神经运动监测已改善了桥小脑角和颅底手术中颅神经功能的保留。需要进一步改进以在术中运动神经刺激期间提供更高的选择性和敏感性。先前的研究者推荐使用双极刺激探针。作者推测，同轴双极刺激器设计可能比现有设计具有重要优势。本研究在大鼠模型和神经耳科学手术过程中，比较了使用同轴刺激器探针进行双极和单极刺激的结果。同轴双极探针在选择性方面更具优势，从而允许进行有用的多通道监测。与先前的双极刺激器设计相比，同轴设计也可能具有优势。
