ABSTRACT
The clinical evaluation methods of facial paralysis can be divided into functional evaluation scales,neuro-electrophysiologi-cal tests and computer evaluation systems.The commonly used function evaluation scales include House-Brackmann Grading Scale(HB-GS),Burres-Fisch Facial Nerve Scoring System,Nottingham System,Sunnybrook facial grading System(SFGS),Degree of Facial Nerve Paralysis Hierarchical Scale,Facial Disability Index(FDI)and Facial Clinimetric Evaluation(FaCE)Scale,etc.Neuro-electrophysiological tests mainly consist of facial electromyography (EMG), electroneurography (ENoG), blink reflex (BR), and neural excitatory test (NET), etc.The computer evaluation system based on the sensor is mainly divided into the computer evaluation system based on infrared thermal image technology and the computer evaluation system based on biomedicine image recognition.This article briefly summarized the existing methods of facial paralysis evaluation in terms of sensitivity,stability,accuracy,ease of operation and economics.
