We studied the sympathetic skin responses (SSRs) in the face with magnetic stimulation of the neck, in 10 normal healthy subjects. The SSRs were recorded with surface electrodes placed on the forehead, the lower eyelid, the apex nasi, two points of cheek (one is near the ear, and another is near the mouth), the upper lip, and the lower jaw. Reproducible SSRs were obtained easily at the forehead and the upper lip compared to the other parts of the face. The SSRs on the forehead and upper lip were constantly evoked after drinking of hot water. Mean latencies are 0.98 +/- 0.22 sec. (mean +/- 1SD) at the forehead, and 0.89 +/- 0.12 sec. (mean +/- 1SD) at the upper lip. In the cervical sympathetic pathway, one part of postganglionic fibers runs along the internal carotid artery to innervate the eyelids and forehead, whereas another part runs along the external carotid artery to innervate other parts of the face. It suggests that the forehead and the upper lip are representative parts of those different innervations SSRs in the forehead and the upper lip could be useful for evaluating the sympathetic function of the face in various diseases.
我们对10名正常健康受试者进行了研究，通过磁刺激颈部来观察面部的交感神经皮肤反应（SSRs）。使用表面电极记录前额、下眼睑、鼻尖、脸颊两点（一点靠近耳部，另一点靠近口角）、上唇和下颌的SSRs。与面部其他部位相比，在前额和上唇很容易获得可重复的SSRs。饮用热水后，前额和上唇的SSRs会持续诱发。前额的平均潜伏期为0.98±0.22秒（平均值±1标准差），上唇为0.89±0.12秒（平均值±1标准差）。在颈交感神经通路中，一部分节后纤维沿颈内动脉走行，支配眼睑和前额，而另一部分沿颈外动脉走行，支配面部其他部位。这表明前额和上唇是这些不同神经支配的代表性部位，前额和上唇的SSRs可能有助于评估各种疾病中面部的交感神经功能。
