自Esslea和Fiseh将神经肌电图技术介绍至耳鼻咽喉科领域后,目前,已成为一种常用来评定面瘫患者神经退行性改变的方法。但是,对其准确性众说不一。为了研究最佳导联(OLP)和标准导联(SLP)两种记录方法伴随的变异参数并确定和减少造成这类误差的相关因素,作者采用该项方法检查25名正常人的面神经功能。在确定检查误差过程中,通过监视所示波形及大小调整记录电极在鼻唇沟的安放位置直至获得最大的标准双相波形、检验SLP法的误差和确定造成误差的因素(包括记录电极的大小、皮肤电阻、刺激强度等)。实验步骤:采集资料,择用ITV和BV误差值反映各种记录方法的变异参数,经student配对t值检验以确定其统计学意义。结果表明,OLP法准确性最高,平均ITV误差为17.8％;如不根据
Since Esslea and Fiseh introduced neuromuscular electromyography into the field of otolaryngology, at present, it has become a commonly used method for assessing neurodegenerative changes in patients with facial paralysis. However, its accuracy varies. In order to study the variation parameters associated with both OLP and SLP recording methods and to identify and reduce the associated factors responsible for these errors, the authors used this method to examine the facial nerve function of 25 normal subjects. To determine the error in the inspection, monitor the waveform and size of the recording electrode in the nasolabial sulcus until the largest standard biphasic waveform is obtained. Verify the SLP error and determine the cause of the error (including the size of the recording electrode Skin resistance, stimulus intensity, etc.). Experimental steps: collecting data, select the error value of ITV and BV to reflect the variation parameters of various recording methods, and test the student’s t-value to determine the statistical significance. The results show that the OLP method has the highest accuracy with an average ITV error of 17.8%, if not based on it
