移植神经植入术整复面瘫畸形的临床研究

CLINIC STUDY IN PLASTIC FACIAL PALSY BY NERVE GRAFTING AND IMPLANTATION

本文是在系列的实验研究基础上,已充分证明神经植入术运动终板再生。初步应用于临床,矫正面神经损伤面瘫畸形的病例。经过4例临床的初步观察和肌肉电生理功能测定,均呈现出较为满意的效果。本组病例显示在术后3～6个月,面部表情功能有所恢复。肌电图研究证明神经肌肉传导速度和肌电位也得以恢复。手术方法是在手术显微镜下,将移植的耳大神经或腓肠神经同患侧或健侧的面神经颊支相吻合,另一末端分为束组植入到颧大肌、眼轮匝肌、上唇方肌。本文认为,移植神经植入术整复某些由创伤所致的面瘫畸形有较大的临床应用价值。

The purpose of this study is to demonstrate the results of 4 cases of facial paralysis by nerve implantation. This is a primary report. In this series of patients, the minic function has improved by nerve implantations after 3 to 6 months. The EMG studies to be shown impovement of conduction with time. Under operative microscope, facial buccal branch and a nerve grafting is anastomosed, with nerve ends splitted into facicules were implanted into damaged facial mimic muscle, which nerve grafting implanted into muscle zygomatic major, or orbicularis oculi muscle, or quadratus labii superioris muscle by cross facial nerve grafting anastomosed with buccal branch of unparalyzed side.
