The novel midline electroneurography (ENoG) method may have advantages over the standard method in terms of ease of electrode setting, and the ENoG value may be a useful prognostic factor.
We compared ENoG performed in patients with facial palsy using two different methods--the new midline method and standard method--in terms of the amplitudes of the compound muscle action potentials(CMAPs) and relationship between the ENoG value and clinical course.
A total of 64 patients with facial palsy were enrolled. CMAPs were recorded using the midline method, in which the recording electrodes were placed on the mental protuberance and philtrum over the orbicularis oris muscle, and the standard method, in which the recording electrodes were set close to the nasolabial fold. Percutaneous electrical stimulation was applied to the main trunk of the facial nerve.The amplitudes of the CMAPs and the relationship between the ENoG value and the period to full recovery from the facial palsy were compared.
The midline method had larger CMAP amplitudes on both sides and a stronger negative correlation in the relationship between the ENoG value and period to full recovery from palsy than the standard method statistically.
新型中线神经电图（ENoG）方法在电极设置的简便性方面可能优于标准方法，且ENoG值可能是一个有用的预后因素。
我们比较了采用两种不同方法（新的中线方法和标准方法）对面瘫患者进行ENoG检查时，复合肌肉动作电位（CMAP）的波幅以及ENoG值与临床病程之间的关系。
共纳入64例面瘫患者。使用中线方法（将记录电极置于口轮匝肌上方的颏隆凸和人中处）和标准方法（将记录电极置于靠近鼻唇沟处）记录CMAP。对面神经主干进行经皮电刺激。比较CMAP的波幅以及ENoG值与面瘫完全恢复所需时间之间的关系。
与标准方法相比，中线方法两侧的CMAP波幅更大，且ENoG值与面瘫完全恢复所需时间之间的关系在统计学上具有更强的负相关性。
