Electrodiagnostic (EDX) assessment is one of the most important aspects in the evaluation of the two most common disorders of the facial nerve: facial palsy and hemifacial spasm. Facial palsy is usually an acute disorder that resolves in a few weeks but, in a number of cases, leads to a postparalytic facial syndrome featuring muscle synkinesis, myokymia, and involuntary mass contractions of muscles on the affected side. Hemifacial spasm is usually a chronic disorder characterized by paroxysms of involuntary, clonic, and synchronous twitching of all facial muscles on the affected side. EDX studies provide information on lesion location and severity, pathophysiology underlying the two disorders, and differential diagnosis between syndromes presenting with abnormal facial muscle activity. This monograph is intended to describe the most relevant EDX findings in the two disorders and the most appropriate timing for the examinations in order to provide useful information for prognosis and therapeutic decision-making.
电诊断（EDX）评估是评估面神经两种最常见疾病——面瘫和半面痉挛的最重要方面之一。面瘫通常是一种急性疾病，几周内即可痊愈，但在许多情况下，会导致麻痹后面部综合征，其特征为肌肉联带运动、肌束震颤以及患侧肌肉的不自主团块收缩。半面痉挛通常是一种慢性疾病，其特征是患侧所有面部肌肉出现阵发性、不自主、阵挛性和同步抽搐。EDX研究提供了有关病变位置和严重程度、这两种疾病的病理生理学以及表现为面部肌肉活动异常的综合征之间的鉴别诊断等信息。本专著旨在描述这两种疾病中最相关的EDX检查结果以及最合适的检查时机，以便为预后和治疗决策提供有用信息。
