This study was designed to determine the optimal sites for the active electrode in a nerve conduction study of each branch of the facial nerve. Twenty healthy male and female volunteers between 20 and 40 years old were investigated. Our criteria for the optimal site of the active electrode were initial negative deflection and maximal amplitude of the response and the most synchronized response. Optimal sites were found to be as follows: 1. Frontalis (temporal branch): a point midway between the hairline and the eyebrow along a line passing vertically through the pupil. 2. Orbicularis oculi (zygomatic branch): the medial quarter between the medial and lateral canthus. 3. Nasalis (buccal branch): muscle belly. 4. Triangularis (mandibular branch): 15 mm lateral and 25 mm below the corner of the mouth. 5. Orbicularis oris (zygomatic, mandibular and buccal branches): 2 mm below the lower lip midway between the midline and the corner of the mouth.
本研究旨在确定面神经各分支神经传导研究中活性电极的最佳位置。对20名年龄在20至40岁之间的健康男性和女性志愿者进行了调查。我们确定活性电极最佳位置的标准是初始负向偏转、反应的最大振幅以及最同步的反应。发现最佳位置如下：1. 额肌（颞支）：沿垂直穿过瞳孔的线，在发际线和眉毛之间的中点。2. 眼轮匝肌（颧支）：内眦和外眦之间的内侧四分之一处。3. 鼻肌（颊支）：肌腹。4. 三角肌（下颌支）：口角外侧15毫米且口角下方25毫米处。5. 口轮匝肌（颧支、下颌支和颊支）：下唇下方、中线与口角之间中点处2毫米处。
