A new technique in aesthetic plastic surgery called Percutaneous Selective Radio-frequency Neuroablation (PSRN) is proposed. Radio-frequency energy is applied via the percutaneous route to interrupt selected terminal fibers of the facial nerve in order to modify the facial dynamics. An easy-to-construct electronic system is used to perform both three-dimensional perioperative location (by means of electrical stimulation) and percutaneous electrofulguration of the target nerve. PSRN was found useful in ameliorating noticeable forehead and frown wrinkles caused by muscular hyperactivity as well as in achieving a more balanced face in cases of unilateral postrhytidectomy facial paralysis of the temporal branch of the facial nerve. Twenty-one patients underwent PSRN with encouraging results. In this report, the electrophysiological bases, technique, animal experiments, and initial clinical experience of PSRN are presented.
一种名为经皮选择性射频神经消融术（PSRN）的美容整形新技术被提出。通过经皮途径施加射频能量，以中断面神经的选定终末纤维，从而改变面部动态。使用一个易于构建的电子系统来进行三维围手术期定位（通过电刺激）以及对目标神经进行经皮电灼。发现PSRN在改善因肌肉活动过度引起的明显额头纹和皱眉纹方面有用，并且在面神经颞支单侧除皱术后面部麻痹的病例中，有助于实现面部更平衡。21例患者接受了PSRN，结果令人鼓舞。在本报告中，介绍了PSRN的电生理基础、技术、动物实验和初步临床经验。
