A Study on the Correlation Between Electrical Excitability and the Prognosis of Peripheral Facial Paralysis
Clarifying the degree of facial nerve injury in peripheral facial paralysis(PFP)is crucial for predicting prognosis and selecting treatment plans.Electrophysiological tests have been widely used for prognostic inference of PFP.As one of the methods of electrophysiological tests,nerve excitability test(NET)is more easily accepted by patients compared to electroneurography(ENoG)and electromyography(EMG).When treating PFP with electroacupuncture(EA),observing the contraction amplitude of facial muscle group with varying current frequency based on electrical excitability can also provide a reliable prognostic evaluation.The EA excitability and NET are collectively referred to as electrical excitability.The principles of both tests are similar,as they detect facial nerve damage in PFP through electrical excitability and infer the prognosis of the disease.However,there is limited research on electrical excitability and it has not yet been widely used in clinical practice.This article collects and organizes relevant literature in the past 20 years,comprehensively reviewing studies on the correlation between electrical excitability and the prognosis of PFP from the aspects of understanding of electrical excitability,EA excitability,NET,etc.,in order to improve the clinical attention to electrical excitability and provide important references for clinical research and application.
