晚期面神经麻痹修复过程中表情肌与颞肌电生理力学指标的对比研究
Comparative study on electrophysiological mechanic indexes of mimetic muscle and temporalis in reparative process of facial paralysis at advanced stage
摘要
Abstract
BACKGROUND: The shortcoming of excessive strong muscular strength may be produced when the complex tissue valve of temporalis epicranial aponeurosis is used to repair facial paralysis at advanced stage. We made a comparative study on electrophysiological mechanic indexes of mimetic muscle and temporalis in the hope that expressional asymmetry after operation can be avoided.OBJECTIVE: To determine the interference pattern(IP) of temporalis and mimetic muscle by electromyography(EMG) and screen functional index for transferring temporal musculofascial flap in advanced facial paralysis.DESIGN: An open trial.SETTING: Department of Cineplastic Surgery and Anatomy Teaching & Research Section, Nanfang Hospital affiliated to Southern Medical University.PARTICIPANTS: Eighteen healthy young volunteers from year 2000 students of the Military Academy were chosen in this experiment.METHODS: Based on the principle of EMG, IPs of muscle bundle of temporalis and mimetic muscle were determined.MAIN OUTCOME MEASURES: Turns and amplitude of corresponding muscle bundle and their ratio(T/A) were recorded and compared.RESULTS: Muscular strength of the three muscle bundles that could be utilized by temporalis was 1.5 to 4 times as that of corresponding mimetic muscle bundle. The difference was significant.CONCLUSION: Temporalis can be divided into three bundles to substitute mimetic muscle in the repair of facial paralysis at advanced stage, and muscular strength is relatively stronger.关键词
