Abstract

Objective

The aims of this study were to investigate the electrophysiological features of hemifacial spasm (HFS) and post-facial paralysis synkinesis (PFPS) that contribute to differential diagnosis.

Methods

This study was designed as a retrospective analysis, focusing on 132 patients diagnosed with HFS and 78 patients with PFPS between May and October 2023. Patient data were collected from existing medical records. The study aimed to analyze pre-existing electrophysiological data, including abnormal muscle response (AMR) and facial synkinesis, focusing on parameters such as AMR latency, amplitude, and duration.

Results

In the HFS group, AMR could be induced in all patients, with synkinesis present in 31.8 %. In the PFPS group, AMR and synkinesis were induced in 79.5 % and 100 % of patients, respectively. Compared with the PFPS group, the HFS group had a shorter AMR latency and higher amplitude (P < 0.05). The duration of the AMR did not significantly differ between the two groups (P > 0.05). Synkinesis in the HFS group was typically accompanied or followed by an involuntary spasm episode, but not every eye closure or pouting led to synkinesis. In contrast, synkinesis in the PFPS group occurred with every voluntary movement and was synchronized with these movements.

Conclusions

Patients with HFS and PFPS may exhibit similar clinical symptoms. Neurophysiological tests, particularly electromyography, provide valuable information for the differential diagnosis of HFS and PFPS.

神经生理监测在面肌痉挛与面瘫后联动性鉴别中的应用。

目的：探讨面肌痉挛（HFS）和面瘫后联动性（PFPS）的电生理特征对鉴别诊断的价值。方法：本研究采用回顾性分析的方法，研究对象为2023年5 - 10月诊断为HFS的132例患者和PFPS的78例患者。从现有的医疗记录中收集患者数据。该研究旨在分析预先存在的电生理数据，包括异常肌肉反应（AMR）和面部联动性，重点关注AMR潜伏期、振幅和持续时间等参数。结果：HFS组所有患者均可诱发AMR，其中伴动率为31.8%。在PFPS组中，79.5%的患者产生AMR， 100%的患者产生联动性。与PFPS组相比，HFS组AMR潜伏期更短，振幅更高（P < 0.05）。两组间AMR持续时间差异无统计学意义（P < 0.05）。HFS组的联动通常伴随着或随后出现不自主痉挛发作，但并非每次闭眼或噘嘴都会导致联动。相比之下，PFPS组的协同运动发生在每次自主运动中，并与这些运动同步。结论：HFS和PFPS患者可能表现出相似的临床症状。神经生理学测试，特别是肌电图，为HFS和PFPS的鉴别诊断提供了有价值的信息。

期刊介绍： Neurophysiologie Clinique / Clinical Neurophysiology (NCCN) is the official organ of the French Society of Clinical Neurophysiology (SNCLF). This journal is published 6 times a year, and is aimed at an international readership, with articles written in English. These can take the form of original research papers, comprehensive review articles, viewpoints, short communications, technical notes, editorials or letters to the Editor. The theme is the neurophysiological investigation of central or peripheral nervous system or muscle in healthy humans or patients. The journal focuses on key areas of clinical neurophysiology: electro- or magneto-encephalography, evoked potentials of all modalities, electroneuromyography, sleep, pain, posture, balance, motor control, autonomic nervous system, cognition, invasive and non-invasive neuromodulation, signal processing, bio-engineering, functional imaging.
